BJB43 kW – 53V – Water-Cooled (BJB43/53V/V)

Battery BJB43kW – 53V – Water-Cooled

This is a battery storage system suitable for households, with a usable capacity of 30–35kW. The storage unit size is W 880 x D 366 x H 1285 mm and weighs 345 kg. The lifespan of the unit is 8,800 cycles at 94% capacity utilization. The batteries are developed using LiFePO4 technology, which has the safest lithium chemical composition. LiFePO4 is non-flammable, can withstand high temperatures without breaking down, and is not prone to thermal runaway. The battery storage system can charge and discharge with a current of up to 200A. Developed in cooperation with the Czech Technical University (CTU) – Faculty of Mechanical Engineering.
