Low-cost,
rapidly deployable BESS,
from repurposed batteries

We design and deploy containerized battery energy storage that runs on validated second-life EV batteries. Costs less. Ships faster. Works the same.

How we do it · 02

Field-ready,
by design

One containerized chassis. Repurposed EV batteries inside. Drops on a pad or rolls on a trailer, opens for service, and runs at moderate C-rates with cell-level visibility.

Sealed for any climate

Marine-grade enclosure, fire-suppressed, IP54. The unit drops on a pad and starts moving electrons in days, not seasons.

Containerized IP54 rated Pad-mount / skid

Engineered to open

Doors split wide for a full walkthrough. Battery racks, BMS, HVAC, fire panel. Every subsystem reachable in under sixty seconds. Service is a feature, not a quote.

< 60s to any rack Hot-swap capable Field-replaceable BMS

Built for any battery

Our chassis accepts validated battery packs from any EV chemistry or format. NCA, NMC, LFP. Same rack, same BMS, same data plane.

Energy in
Energy out

Repurposed EV batteries, conditioned for cycle work. Charges from solar, grid, or genset. Discharges to your load when rates climb. Every joule tracked through our energy management system.

↑ Charge

Energy flows in

Solar at noon. Off-peak grid at 2 a.m. The pack absorbs whatever's cheap or free.

↓ Discharge

Energy flows out

To your load, your DC fast chargers, your microgrid. When rates are high, or the grid drops.

EMS · energy management

Watched cell by cell

The EMS is what turns repurposed batteries into infrastructure-grade storage, precise enough for workloads that can't afford a wobble. AI data centers, first. Microgrids, grid services, and EV fast charging right behind.

Cell-level monitoring on a 1-minute cadence, pack telemetry at 1 Hz or faster, sub-cycle dispatch, grid-forming or grid-following on demand. SCADA / DCIM tie-in.

Power that arrives

Same chemistry, same EMS, same control plane as the pad-mount fleet. Hitched to a trailer. Drop it anywhere a truck can go and the power follows.

Plug Park Power

01 EVENTS · JOB SITES

Power an event,
anywhere

Concerts. Film sets. Construction. Festivals. Wherever the meter doesn't reach. Quieter than a diesel genset, with telemetry instead of guesswork.

02 EV FAST CHARGING

Charge a fleet,
no utility upgrade

Stand up DC fast charging on a fleet yard, a dealership pop-up, a race weekend, a route gap. Multiple vehicles at once, no transformer wait list.

03 DISASTER · OUTAGE

Roll-in microgrid,
lights stay on

Storms, wildfires, public-safety shutoffs. The trailer pulls up, forms its own grid, and keeps critical loads alive while the utility works the line. Black-start capable, solar- and genset-ready.

What sets us apart · 05

Three things
no one else does together

01

A chassis that takes any battery

Our containerized hardware accepts validated battery packs from any EV chemistry or format. NCA, NMC, LFP. Same rack, same control plane, same data.

  • Chemistry-agnostic
  • Format-flexible
  • Field-serviceable
02

Advanced control and energy management

Cell-level BMS. Grid-following or grid-forming on demand. Pack telemetry at 1 Hz or faster, OCPP-aware dispatch, SCADA / DCIM tie-in. Every joule logged and accounted for.

  • Grid-forming capable
  • Cell-level BMS · 1‑min cadence
  • Pack telemetry at 1 Hz
03

End-to-end integration

We own the path from battery intake to deployment to ongoing service. You own the kilowatt-hours. No procurement chain, no integrator markup, no finger-pointing.

  • Battery to BESS
  • Built in California
  • One team, one number

Use cases · 07

Where it runs

Same hardware. Three jobs it does better than the alternative.

01 / AIDC

AI data centers

Behind-the-meter storage that rides through grid events, defers substation upgrades, and shaves demand charges while your GPUs eat power. Every joule logged at 1 Hz, tied into SCADA / DCIM.

  • Demand-charge mgmt
  • UPS-class backup
  • SCADA / DCIM tie-in
02 / MICRO-GRID

Micro-grid

Island a campus, a clinic, a downtown block. Black-start capable, grid-following or grid-forming on demand. Solar- and genset-native.

  • Grid-forming
  • Solar & genset native
  • Black-start capable
03 / MOBILE

Mobile power

Same chemistry on wheels. Drop it anywhere a truck can go. Job sites, fleet yards, disaster relief, film sets, EV-fast-charging pop-ups. Quieter and cleaner than a diesel generator, with telemetry.

  • Trailerable
  • Diesel-replacement
  • Off-grid ready

Move the bill down
Move the carbon off

Storage isn't a feel-good buy. It pays back. Drag the slider. Conservative numbers: no incentives, no ITC, just demand-charge avoidance and grid emissions math.
