BMS 3.2V 50A 3S 4S for LiFePO4
50A BMS with balancing function that will work in either as a common port or split port setup. This universal module can be used in 3S, 4S, or 5S configurations for LiFePO4 cells, by soldering the correct jumper setting on the board.
THE MODULE WE SHIP IS PRE-CONFIGURED FOR 4S OPERATION. TO SET TO 3S or 5S you will have to re-solder the junctions in the picture, PLEASE SEE PICTURE.
THIS MODULE WILL ONLY WORK WITH LITHIUM IRON PHOSPHATE CELLS, DO NOT USE WITH REGULAR LITHIUM ION.
