Development modularity battery storage, which consists of 1-8 battery modules. Modules can be connected in parallel circuits or series circuits for different voltages of the system. The design of modules allows install and connect them just by putting one on top of the other.
Firstly we assembled two batteries (LiFePO4 elements, 48 V) and tested charging and loading in parallel circuit and series circuit.
Pre-production 1,2 kWh sample has been assemble with 80 batteries and BMS for 48V.
