● Battery quality
Long lifespan: 6000 cycles @ 25 ℃, 0.25C charge discharge rate, 90% DOD
International certification for battery cells: IEC62619, UL1973, UL9540A, UN38.3, GB/T 36276
Meet the most stringent intrinsic safety requirements for battery cells.

● modular design 
Avoid short circuits between battery cells; Flexible buffering between battery cells, overall elastic constraint, reducing the impact of cell expansion;
The air duct between battery cells effectively controls heat accumulation and thermal runaway.

● Flexible selection of high voltage box
