I have a 48 volt 16S 150A LiFePO4 battery system. I used a BMS that consisted of small PCBs that attached directly to each of the cells, daisy chained, and back to a small control board. I bought the BMS from electriccarparts.com in Utah. I want to buy more of these BMS systems, but ECP doesn't sell them anymore. Does anyone know where I can buy these BMSs, or ones similar? I want to avoid the larger PCB type with a small wire going to each cell. Thanks.
