It has a rugged ABS case with flame retardant material, which encloses grade-A prismatic cells that provide a more stable performance than cylindrical battery cells. Suitable for parallel or series connection, fast-charging, and equipped with a built-in BMS, this power pack incurs a lower total cost of operation during its battery life & delivers better overall reliability.
