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.
