low-temperature discharge performance

Outstanding Ultra-Low Temperature Discharge Performance

The cell maintains full 10C rated discharge performance steadily at -40°C, outputting stable rated power without capacity attenuation in frigid sub-zero environments to guarantee reliable power supply.

Powerful Continuous High-Current Output

Rated at 10C max continuous discharge, this 40Ah cell supports up to 400A sustained discharge current. It is perfectly suitable for cold-climate scenarios including heavy equipment startup, high-power inverters and electric vehicle traction systems.

High-Safety LiFePO₄ Core Chemistry

Built with lithium iron phosphate material featuring exceptional thermal stability. Its unique chemical structure delivers excellent tolerance to extreme low temperatures and drastically reduces risks of thermal runaway for safer operation.

Modular Prismatic Cell with Robust Durability

Standard prismatic form factor supports flexible series/parallel stacking for easy system assembly. The rigid casing enables uniform heat dissipation and superior mechanical stability, ideal for heavy-duty industrial energy storage deployments.
