Production Crew
How to use this document. The production lead should review Section A before show
start and brief any crew member who may interact with the ThunderBank. Keep the laminated
Production Crew Emergency Card visible near the unit and the
Fire Department Quick Reference Card ready to hand off on arrival. No signed acknowledgement is
required — the fact that this document is provided and posted is the record of due diligence.
1. What this unit is
The ThunderBank is a mobile lithium battery energy storage system (BESS) housed in a truck box. It stores
270 kWh of LiFePO4 (lithium iron phosphate) at 48 V DC nominal and delivers up to 90 kVA of
208 V 3-phase AC power to the fleet ("ThunderBolts").
Charge sources (four independent paths):
3-phase shore — up to 275 A per leg at 208 V (camlocks on the front-right exterior)
Single-phase trickle chargers — two 50 A single-phase inputs (one hot leg each)
Truck engine-driven alternator — provides DC charging while the truck engine is running. Switch
is located left of the steering wheel in the cab. If the switch's indicator light is illuminated, the
alternator has faulted; leave the switch OFF until Lightnin clears the fault.
Rooftop solar — ~2,900 W of solar panels feed DC into the bank via an onboard
MPPT charge controller. The onboard PV isolation breakers live on the right wall at the front,
beneath the MPPT, in a shielded breaker box (inside the truck box; not field-accessible).
Customer-added external solar (optional) — three additional external PV inputs are
available so a customer can connect supplemental solar panels. The breakers are located
directly above the plug-ins, by the fire extinguisher on the rear bumper, and must be
turned OFF before connecting or disconnecting solar panels.
Power outputs beyond the ThunderBolt feed:
AC Output Panel — "Waterfall" panel of camlock plug-ins. Each row has Ground (green),
Neutral (white), Leg 1 (red), Leg 2 (blue), Leg 3 (black) to provide 3-phase 208 V power.
Level 2 EV charger — stored in a black jockey box on the front right of the truck box. The
customer deploys and plugs it in to charge an electric vehicle from the bank's AC output.
Hazards to be aware of: high-voltage AC at connection points, stored electrical energy in the
batteries, and standard vehicle hazards (truck fuel, engine fire, collision).
The battery system is built and tested to recognized UL and IEC safety standards: UL 1741,
UL 1973, and UL 9540A (or European safety standards — IEC 62619, IEC 62620, UN 38.3).
UL 9540A specifically validates that thermal runaway in a single cell does not propagate
to adjacent cells or modules. LiFePO4 is the safest common lithium chemistry — its
thermal-runaway onset is far higher than NMC chemistries, and it does not release oxygen during
decomposition — but it still demands respect.

If you see active fire or smoke, CALL 911 first, then call Lightnin.
3. Quick-response table
If you see / hear / smell…
Do this
Smoke or flame from the truck box
1. Hit the EMERGENCY STOP button (rear right corner, exterior).
2. Call 911. 3. Call Lightnin. 4. Evacuate to 50+ ft.
Do NOT open the personnel door.
Burning-plastic or sweet/chemical odor
Hit EMERGENCY STOP, evacuate, CALL 911, call Lightnin. Treat as a fire indicator
until cleared.
Hissing, popping, or unusual sound from box
Hit EMERGENCY STOP, CALL 911 to be safe, then call Lightnin.
Skip the action only if you can clearly identify the sound as routine: truck airbags,
tires, inverter clicks, breaker trips.
Visible melting, scorching, or discoloration at a camlock or 120 V Edison receptacle
Likely a bad cable or overloaded cable specs — not a fire indicator on its own.
Call Lightnin and verify no other problems. Do not reuse the cable
or plug without maintenance — the affected connector must be inspected
and replaced before the unit is returned to service.
Small flame or arcing at an exterior camlock or Edison receptacle (no fire inside the box)
Hit EMERGENCY STOP first. If safe to do so, use the
ABC fire extinguisher (attached to the bumper, rear left of the
truck) to knock down the flame. CALL 911 if the fire does not
immediately go out, spreads, or you suspect it may have reached inside
the box. Call Lightnin. Do not risk your personal safety
— when in doubt, evacuate.
VRM alert: interior compartment at or above 100°F, or input/output panel at or above 120°F
Check VRM to see which sensor triggered. Consider reducing loads if possible,
and call Lightnin. See the temperature response ladder in §6 for escalation.
Automatic EMERGENCY STOP at 119°F interior compartment or 140°F input or output panel.
Electric shock / arcing at a connection point
Do not touch the person if still in contact with the source. Hit
EMERGENCY STOP. CALL 911. Call Lightnin.
Water leaking into the truck box
Hit EMERGENCY STOP. Disconnect external shore feed if safe to do so.
Stay back, call Lightnin.
Truck fuel spill (truck fuel tank or engine)
Shut off the truck engine. Hit EMERGENCY STOP on the ThunderBank
(the E-stop covers the alternator DC path). Eliminate
ignition sources, evacuate 50+ ft, call Lightnin and follow
standard fuel-spill protocol for your site.
Truck engine fire or engine-bay smoke
Shut off the engine if you can safely reach the cab. Hit EMERGENCY STOP
on the ThunderBank (it disconnects the alternator and MPPT for you if
the cab is unreachable). CALL 911 then call Lightnin.
A truck fire can spread to the BESS — do not assume the box is
unaffected just because the cab is the visible source.
Vehicle collision / accident
Do not approach the truck box until safe. If accessible and safe,
hit EMERGENCY STOP (it covers the alternator disconnect). Call Lightnin.
CALL 911 if you notice other signs of emergency (injury, fire,
smoke, fuel leak, arcing).
ABC fire extinguisher — when to use it.
An ABC-rated fire extinguisher is mounted on the bumper at the rear left of the truck. It is
appropriate only for a small, external, isolated electrical fire (a single camlock or Edison
receptacle arcing or flaming, with no fire inside the truck box). Hit EMERGENCY STOP first, then use
the extinguisher if you can do so safely from outside the box.
For anything larger, any fire inside the box, any thermal-event indicator on the bank itself, or any
uncertainty: do not use the extinguisher. Evacuate, CALL 911, call Lightnin. Do not risk
your personal safety. When in doubt, evacuate.
4. EMERGENCY STOP button
Location: Rear right corner of the truck box, to the right of the AC output panel. Marked with a
red and white EMERGENCY STOP decal with an arrow pointing to the button.
How to use: Press the button firmly. It will lock in place. To reset, twist clockwise per the
decal arrow (only after Lightnin clears the unit).
What it does:
Cuts power to all three inverter banks
Disconnects AC Input
Disconnects AC Output
Disconnects the truck alternator DC charge path
Disconnects the MPPT — halting all solar charging (rooftop and any customer-added external)
Isolates the batteries (they remain online but no current flows in or out)
Cutting the MPPT under load carries a small risk of damaging the MPPT. In a true emergency this is
acceptable — stopping the flow of power is the priority. When time allows (non-emergency, or an
early-stage incident where you can act deliberately), hitting the PV breakers first is preferred.
Before resetting: the incident that triggered the EMERGENCY STOP must be resolved
(fire out, thermal event passed, fault diagnosed) and the scene confirmed safe by production crew.
Do not reset the EMERGENCY STOP until you have notified Lightnin and Lightnin has cleared the unit.
Most events are inverter faults or false positives — Lightnin can guide the reset over the phone
in those cases. For a true thermal or fire event, the unit returns to the shop for inspection before
it is cleared.
5. Truck alternator
The truck's engine-driven alternator can charge the bank while the truck is running. It is not
intended to be used to charge the batteries while parked. It runs automatically and charges the
batteries up to 95% before powering down the field.
Location: Inside the truck cab, left of the steering wheel.
Fault indicator: If the switch's indicator light is illuminated, the alternator has
faulted. Leave the switch in the OFF position until Lightnin fixes the problem.
Manual disable: The switch can be used for tech-level maintenance disconnect
to prevent the alternator from turning on.
Best practice during an emergency: shut off the truck engine if you can safely reach the cab
(good general practice for any incident involving the truck) and hit the EMERGENCY STOP button.
If the cab is unreachable, the E-stop alone covers the alternator DC path.
6. Temperature monitoring — preventing equipment damage and fire
Each AC panel has a built-in temperature sensor and electrical fire suppression housed in a sealed
enclosure. A separate interior compartment temperature sensor monitors the interior of the truck box,
which is air-conditioned to 80°F; the panel sensors normally read within 20°F of the interior compartment temperature.
A VRM alert triggers when the interior compartment sensor reaches 100°F (clears at
95°F), or when the input panel or output panel sensor reaches 120°F
(clears at 110°F). The alert names the sensor that tripped. Regardless of which one it is,
action is required — open the VRM Advanced page to compare all three temperatures and
monitor the trend. Then follow the response ladder below for the sensor that is climbing.

140°F
EMERGENCY STOP — manual or automatic
The unit trips the EMERGENCY STOP on its own; hit the E-stop yourself if you have not already. Call Lightnin. Call 911 if any indication of a fire.
Automatic EMERGENCY STOP at high temperature. The ThunderBank will trigger the
EMERGENCY STOP on its own if the interior compartment reaches 119°F or a panel sensor reaches
140°F. These auto-shutdowns are the last safety layer — they cut power and isolate the
system before temperatures climb into the range where a fire could start.
AC panel fire suppression. If a fire does start inside either AC panel, a fire
suppression device will disperse an aerosol agent to extinguish it. We cannot directly confirm
whether the suppression has deployed, but we can monitor the temperature trend in VRM.
7. Personnel door — do NOT open during a fire
The truck-box personnel door is locked. The driver does not have the combination. The door is intended for
maintenance or emergency only.
During an active or suspected fire, do not open the door. Opening it floods the box with
oxygen and can accelerate the fire. The correct response is: hit EMERGENCY STOP,
evacuate, CALL 911 then call Lightnin. The fire department will either get the combo over the phone from Lightnin
or force entry with an axe, in coordination with Lightnin.
8. DO NOT
Do not open the personnel door during a fire, suspected fire, or any temperature alert without Lightnin guidance
Do not touch any camlock connection (Green / White / Red / Blue / Black) when the unit is energized
Do not attempt to extinguish a battery fire yourself — this is a job for the fire department
Do not spray water on the AC panels while energized — the panels have their own suppression
Do not reset the EMERGENCY STOP button until Lightnin has cleared the unit
Do not restart the truck engine after an alternator-fault indicator until Lightnin clears it
Do not allow untrained personnel inside the truck box
9. Evacuation
Hit the EMERGENCY STOP button (rear right corner of truck box). This disconnects the
alternator and the MPPT along with the inverters, so it is sufficient on its own if the cab is
unreachable.
Shut off the truck engine if you can safely reach the cab (good general practice for any
truck-involved incident). The cab alternator switch is not required — the E-stop
already covers that path.
Move all personnel to at least 50 ft from the truck
CALL 911 if there is any fire, smoke, or suspected thermal event
Call Lightnin at 678-472-5682 (backup 470-244-3905, third priority 877-433-0313)

Battery chemistry
LiFePO4 (lithium iron phosphate)
Capacity
270 kWh total · 243 kWh usable
DC bus
48 V nominal
AC output
208 V 3-phase / single-phase, 90 kVA
Component certifications
UL 1741 · UL 1973 UL 9540A or equivalent
What each standard covers:UL 1741 — inverter / power conversion equipment safety and grid interconnection.
UL 1973 — battery system safety for stationary, motive, and light electric rail applications.
UL 9540A — standard test method for evaluating thermal runaway fire propagation in BESS.
What we mean by “or equivalent.” Some units' batteries have met the
pertinent IEC tests — IEC 62619 (lithium cell / battery safety for industrial
applications), IEC 62620 (lithium cells / batteries for industrial applications —
performance and dimensions), and UN 38.3 (transport safety testing for lithium batteries
per the UN Manual of Tests and Criteria, Section 38.3) — and are also going through
UL 9540A testing. UL 9540A certification is pending for those units.
LiFePO4 is water-suitable for thermal events — copious water flow is the recommended
suppression and cooling approach. Unlike NMC chemistries, LiFePO4 does not undergo violent thermal runaway
and produces less toxic vapor, but SCBA is still mandatory.
2. On-arrival checklist
Confirm the EMERGENCY STOP button has been pressed (rear right corner of truck box, red and
white decal). If not, press it before approaching connection points.
Confirm the truck engine is OFF if the cab is safely accessible. The EMERGENCY STOP
disconnects the alternator DC charge path on its own, so operating the cab alternator switch
(left of the steering wheel) is no longer required — but the switch is still there for
awareness, and its indicator lights when the alternator has faulted.
Visually confirm camlock connections at AC Input and AC Output are not arcing.
Establish a 50 ft minimum stay-back zone upwind of the truck box. Expand to
100 ft if active venting, audible relief, or visible flame is observed.
Call Lightnin at 678-472-5682 (backup 470-244-3905, third priority 877-433-0313) for live consultation. Lightnin can grant
incident command real-time VRM telemetry access (cell temperatures, voltages, alarms).
Vehicle hazards remain: the BESS is housed in a truck, so standard automotive risks
(engine fire, fuel tank, collision damage) are in play independent of the battery system. A truck-cab fire
can spread to the BESS in the box. Treat the box as potentially compromised any time the truck has been in
a collision, even with no visible BESS damage.
3. Firefighting approach
For a battery thermal event
Water suitable. LiFePO4 responds well to copious water for cooling. Apply liberally; do not
ration. Continue water application until cell temperatures stabilize.
Reignition risk: monitor the unit for at least 24-48 hours after extinguishment.
Lithium battery fires can re-light from residual heat trapped in damaged cells.
PPE: full structural turnout gear with SCBA mandatory. LiFePO4 produces less toxic vapor than
NMC chemistries but still releases HF gas and organic vapors during thermal runaway.
Runoff: water used on the unit may carry electrolyte residue and metals. Contain runoff where
practical and notify environmental authorities per local protocol.
Water — preferred. NFPA 855 identifies water as the preferred suppression agent for
lithium-ion battery fires: superior cooling, widely available, and considered safe for use on
high-voltage battery systems. Effective at containing the fire even when battery module geometry
limits water penetration to the cells of origin.
Dry chemical powder — not sufficient alone. Can knock down visible flame but does not
cool the cells. Thermal runaway typically continues inside the battery and can reignite.
CO2 and clean-agent gases — not sufficient alone. Extinguish visible flame
but do not provide the cooling needed to interrupt thermal runaway. Effective only in enclosed
systems designed and ventilated for gas-based suppression.
For an electrical fire in an AC panel
Each AC panel has integrated electrical fire suppression in a sealed enclosure. Activation
cannot be directly confirmed, but Lightnin can monitor interior compartment and panel temperature trends in
VRM as a proxy for whether the event is contained.
Confirm EMERGENCY STOP is pressed before approaching the panel directly. The E-stop
disconnects inverters, AC in/out, alternator, and MPPT/solar.
Treat as a standard electrical fire (Class C) until you confirm batteries are not involved.
4. Hazard awareness
Stored DC energy: ~270 kWh at 48 V even when the EMERGENCY STOP is pressed. Batteries are
isolated from the inverters but still hold a charge.
Solar charging (rooftop + any customer-added external) is stopped by the EMERGENCY STOP via
MPPT disconnect. If the E-stop cannot be confirmed, the external PV breakers (rear-left, near the
fire extinguisher) provide field-accessible isolation for any customer-added solar.
Re-energization: the EMERGENCY STOP is mechanically latched. Do not reset until Lightnin clears the
unit.
Truck-box panels may be hot to the touch in the area of an active event — thermal-imaging camera
recommended before approach.
5. Disconnect and connection locations
EMERGENCY STOP
Exterior, rear right corner of truck box, to the right of the AC output panel. Red/white decal
with arrow.
Alternator switch
Inside the truck cab, left of the steering wheel. Not required to operate during an
emergency — the EMERGENCY STOP disconnects the alternator DC charge path.
Retained for fault indication (illuminated indicator = alternator fault; leave OFF until
cleared) and for tech-level manual disconnect during maintenance.
AC Output
"Waterfall" panel on the right side of the rear wall (exterior). Camlocks: Green / White / Red
/ Blue / Black.
AC Input
Exterior, front right side of truck box, labeled "Input Only". 3-phase camlocks mounted
vertically. Single-phase camlocks mounted horizontally, directly below the 3-phase set.
Internal AC panels
Two enclosures in the ceiling, center of the truck box. Forward enclosure = AC Input. Rear
enclosure = AC Output. Both have integrated temperature sensors and electrical fire suppression.
DC bus bars (per inverter bank)
Located beneath each of the three inverter banks. Individual DC runs from each bank rise
into the ceiling and join at the bus combining point. Internal — not field-accessible
during a fire.
DC bus combining point
Ceiling, forward of the AC Input panel. Where the three per-bank DC runs join into a single
bus before reaching the battery isolation.
Rooftop solar (~2,900 W)
Solar panels on the roof feed DC into the bank via an onboard MPPT charge controller. The
EMERGENCY STOP disconnects the MPPT, stopping all solar charging (rooftop and any
customer-added external, which share the same MPPT).
Onboard PV breakers (rooftop solar)
Inside the truck box, right wall at the front, beneath the MPPT, in a shielded breaker
box. Not field-accessible in a major fire. Not required during an incident —
the EMERGENCY STOP already stops solar via MPPT disconnect. Used for tech-level isolation
during maintenance or MPPT service.
External PV breakers (customer-added solar)
Exterior, in a shielded breaker box at the rear left corner of the truck box, near the
ABC fire extinguisher. Three breakers isolate the optional customer-added external solar
inputs. Field-accessible. The EMERGENCY STOP already stops external solar via MPPT
disconnect, but these breakers are the preferred first move when time allows because they
cut the input before the MPPT (no MPPT damage risk).
Level 2 EV charger
Stored in a black jockey box on the front right of the truck box. Customer deploys it to charge
an electric vehicle from the bank's AC output.
Display (exterior repeater)
Exterior, rear right corner of the truck box — inside an unlocked grey Polycase
enclosure. Same live data as the interior Ekrano: real-time power flow and alarms (Alarms = 4th
blue tab at top of screen). Use this without opening the personnel door. The Ekrano GX
itself is mounted inside the locked compartment, on the left, ~5 ft above the floor, but
is not needed for monitoring during an incident.
6. Personnel door access
The truck-box personnel door is combination-locked. Two access paths:
Call Lightnin for the combination over the phone. Preferred when there is no active fire.
Force entry with an axe. Acceptable when speed matters and Lightnin cannot be reached.
Before opening the door during an active fire event: coordinate with Lightnin if possible.
Opening the door floods the truck box with oxygen and can accelerate combustion. AC-panel suppression is
inside a sealed enclosure, so opening the truck-box door does not disturb the suppression atmosphere
— the concern is purely about adding oxygen to a thermal event in the box.
7. Lightnin coordination
Lightnin 24/7 emergency:
Primary
678-472-5682
Backup
470-244-3905
3rd Priority
877-433-0313
Lightnin can grant the incident commander real-time VRM portal access (battery cell temperatures,
voltages, alarm history, AC input/output power) for the duration of the incident.
Appendix
Reference & Disclaimers
A. Off-gassing during a battery thermal event
Off-gassing typically precedes visible flame by minutes — it is the earliest reliable
warning of a lithium battery thermal runaway. The byproducts and their warning signs are well-documented
for LiFePO4 chemistry in Sandia National Laboratories and NFPA Research Foundation studies; the same
profile applies to this unit.
White or grey vapor venting from the truck box, even without flame, indicates electrolyte
vaporization is in progress. Treat as a fire event: hit EMERGENCY STOP, evacuate to
100 ft, CALL 911, call Lightnin.
Sweet, ether-like, or solvent-like odor — electrolyte carbonate vapor (DMC, EMC, DEC).
Distinctive enough that crew should learn to recognize it.
Pungent, acidic, eye/throat-irritating odor — hydrogen fluoride (HF) gas. LiFePO4
produces less HF than NMC chemistries but does still release some during runaway. Evacuate
upwind.
Burnt plastic odor — internal insulation or wiring damage. Often signals the event has
progressed beyond initial cell venting.
B. Customer / production-side pre-show safety checks
Because the ThunderBank moves between sites, the EAP cannot pre-fill site-specific information. Before
each show, the production team must identify and be aware of:
Production site street address (for 911 dispatch — lat/lon if no street address)
Nearest hospital with an emergency room
Local fire department non-emergency number and their station address
On-site safety officer or production manager name + phone
Designated evacuation assembly point (visible from the truck location)
Confirmation that the ABC fire extinguisher (rear-left bumper) is present and within its inspection date
C. Post-incident reporting
After any incident involving the ThunderBank (whether or not the unit was damaged), report the
following to Lightnin as soon as it is safe to do so. Lightnin uses this to investigate root cause and
update procedures.
Date, time, and duration of the event
Location (site address)
What was first seen / heard / smelled, and by whom
Photos or video of the unit and any visible damage — only if safe to capture
D. Mobile BESS regulatory context
The ThunderBank is a mobile battery energy storage system. The principal published BESS
standards — NFPA 855 ("Standard for the Installation of Stationary Energy Storage
Systems"), IFC 1207, and NEC Article 706 — were written for stationary installations in
fixed buildings. By their own terms they do not directly govern mobile BESS, and as of 2026 there is
no unified US regulatory standard specific to mobile BESS.
Lightnin's approach is to follow stationary BESS best practices as closely as possible where they
map to a mobile build. The ThunderBank is built to best electrical practices, and component-level
safety is validated to recognized standards listed in the Quick Facts — UL 1741,
UL 1973, and UL 9540A (or the equivalent IEC 62619 / IEC 62620 / UN 38.3).
These component certifications apply regardless of stationary vs. mobile installation.
Where a local AHJ has mobile-specific or event-specific requirements, those supersede this document.
Operators should confirm AHJ requirements during the pre-show safety check described in section B.
E. Disclaimer and scope

Summary of changes
Rev 1
2026-06-12
Initial release.
Rev 2
2026-08-06
EMERGENCY STOP upgraded — now also disconnects the truck
alternator DC charge path and the MPPT (which halts all solar, rooftop and customer-added
external). Cab alternator switch reframed as redundant to the E-stop and retained for fault
indication / maintenance use. Rooftop-tarp guidance removed. PV breakers noted as preferred
first move when time allows, to avoid MPPT damage risk from cutting under load.
Revision to fire prevention approach and additional VRM alarm added for interior compartment
temperature (100°F alarm clearing at 95°F, manual shutdown at 114°F, automatic E-stop at 119°F).
Panel sensor ladder: 120°F alarm, isolate at 130°F, manual OFF at 135°F,
manual or automatic E-stop at 140°F.
Temperature response ladders added for interior compartment and panel sensors. NFPA 855 suppression
agent guidance added to the firefighting approach.
