I like this BMS! It has LED's so you can see what cells are being "balanced " (bleeding of 50mA ? curent from the top charged cells ). The 3.2V version looks to be for Lithium iron phosphate (Li-Fe-Po4) cells, and the "3.7V" version is for Lithium ion (Li-ion) 4.2V cells. The lifepo4 3.2V version uses the BM3451- BHDC-T28A, and the Li-ion 3.7 (4.2V) version uses the BM3451 -SMDC-T28A chip. So you need to buy the right version that fits your needs/battery cells. the chip can also be used for 3S, 4S and 5S configuration. you just have to remove one or two 0-ohm resistors of you wanna use a 3S BMS for 5 cells. the PCB is good quality, but I haven't tested it under high current over time. The controller chip on one of my BMS was mounted outside it's footprint, so I had to heat it up and move it.. anyways.. this BMS is sofar my favorite when it comes to tiny BMS'es.

Když jsem modul prohlédl všiml jsem si že je špatně připájená součástka. Poslal jsem foto na servis BG a oni mi pošlou novou desku. Děkuji Banggoog za snadné vyřešení reklamace.

these boards are excellent … the shipping was fast for the first time ever. I made a battery pack today , a 5S Lion pack to replace my old Nicads and the project went well! good Board! thanks
