Immersion Cooling Battery Storage
Our immersion-cooled battery systems submerge every cell in dielectric coolant — IP68 packs, cell-to-cell spread ≤2°C, -30 to 60°C operation, and ≥8,000-cycle system life — engineered for sites where fire risk is not an option.

Highlights
Cells sit in dielectric, flame-retardant coolant — the ignition triangle loses oxygen contact and heat buildup at once.
Single-phase immersion cools 100% of the cell area, holding spread ≤2°C where cold plates cool one face.
IP68 pack construction protects through transport and installation; no coolant service under normal operation.
The 225kWh cabinet runs this chemistry architecture in commercial service — see commercial ESS.

Four product lines — vehicles, energy storage, farm machinery and engines — from long-established Chongqing manufacturing bases, exported through one channel under one QC standard.
- One mixed container — vehicles, batteries, machines and spares ship together; 220+ SKUs on one loading plan cuts freight and admin cost per line.
- One QC & export standard — factory specification sheet and certification status attach to every quotation, answered within 24 hours.
- Field-proven flagship tech — immersion-cooled storage in oilfield service since 2022 at 8.1% of diesel energy cost.
- SKD / CKD routes — local-assembly programs ready where import policy requires them.
How to Choose
- Site load before capacity — size from measured peak demand and backup hours; 225kWh and 261kWh cabinets cover most C&I peak-shaving sites.
- Thermal strategy — fully-immersed LFP holds cell spread within 2°C and supports ≥8,000 cycles; standard cabinets fit budget installs.
- Environment — oilfield and remote duty takes the workover-proven configuration running since 2022 at 8.1% of diesel energy cost.
- Grid role — peak shaving, backup or solar pairing changes inverter sizing; confirm with your load profile in the RFQ.
Where this line sits
The immersion-cooled 225kWh sits at the flagship end — the safety ceiling of the line where cell temperature is engineered, not hoped for.
Stationary Storage Family Finder

How It Performs in the Field
The pain points buyers raise most — and what the line does about them:
- Air-cooled cabinets develop hot spots and cycle degradation — coolant in direct cell contact holds spread within 2°C and supports ≥8,000 cycles.
- IP68 pack construction takes thermal management out of the machine room and into the fluid, where it is controllable.
Trade & Ordering Notes
- Mixed loading is standard — mixed models and mixed categories in one container are accepted; per-model MOQ is confirmed in the quotation.
- 24-hour quotations — specification-matched replies on business days, with the factory specification sheet and certification status attached.
- Terms confirmed in writing — payment, production lead time and warranty are fixed per model and destination in the quotation, with no post-signing surcharges.
- Export-ready documentation — HS classification and the export document set are issued per model; SKD/CKD component programs are available where market policy requires local assembly.
How We Work with You
FAQ
How does immersion cooling prevent thermal runaway?
Cells are fully submerged in dielectric, flame-retardant coolant — removing oxygen contact and absorbing heat at the cell surface, so the ignition triangle loses two of its three sides.
Is immersion cooling better than cold-plate liquid cooling?
Cold plates cool one face; immersion cools the entire cell surface, holding spread ≤2°C and eliminating local hotspots.
What cycle life does it achieve?
≥8,000 cycles at 70% SOH EOL, 95% DOD, 25°C on the 225kWh system.
Does it work in extreme climates?
The design range is -30°C to 60°C, with coolant properties maintained across the range.
