Battery BJB43kW – 53V – Heated (BJB43/53V/H)

 This is a battery storage system suitable for households, with a usable capacity of 30–35 kWh. The storage unit dimensions are W 790 × D 296 × H 1285 mm, with a weight of 315 kg. The expected lifetime of the storage unit is 8,800 cycles at 94% capacity usage. The batteries are developed using LiFePO4 technology, which offers the safest lithium chemistry. LiFePO4 is non-flammable, can withstand high temperatures without decomposition, and is not prone to thermal runaway. The battery storage system can charge and discharge at a current of up to 140 A. Developed in cooperation with CTU – Faculty of Mechanical Engineering.
