Anmbest Charger Protection Lithium Battery Review

I needed a board that I could use to protect the battery during discharge/use. I will not provide charge from the circuit, only discharge. They are not suitable for my use as reading the description said this should work for me I'm giving it a 2*. I connected B+, B- and BM as indicated. I connected P- and P+ to my circuit (they are connected to the LM2596 to reduce the voltage). It's not stressed at all. I read here in the comments that if I bridge P-/B- it works. It then supplies electricity…

I chose it for testing because of its high current rating (8A max) and simple design for isolating the batteries from external circuits. It's tiny and easily fits in the curved space between two 18650 cells or in the middle of a block of four. In my test setup, the circuit board is in a shrink tube between two cells. No heat issues so far, but haven't tested full load or low voltage shutdown situations. The charging circuit appears to be working properly. Input and output are just two wires (V+

My Revain electrically heated gloves were a BARGAIN for the price I bought them for. but inside were LiPO batteries in 2S configuration (4.2 + 4.2 = 8.4V) which died after one full use! In fact I think the controller circuit didn't have any low end cutoff and I left them on until they died and of course ruined the batteries forever. My plan was to replace them with double capacity Lithium 18650s (not LiPO), but I had no idea how to charge them in a 2s configuration. After some searching I found
