Review on π HiLetgo 14.8V 4S 30A 18650 Li-ion Lithium Battery BMS PCB Protection Board with Cell Balance β Integrated Circuits by Allen Tchida
Worked fine once I figured out the wiring
As others have said, this BMS is very lacking in documentation. I finally found schematics on other sites and hooked them up correctly. Attached to this review is a schematic from the same BMS listed elsewhere. Hope this helps someone. On the plus side, it didn't light up when I plugged it in the wrong way. Large pads for soldering B+/- P+/- and balance wires are very good. Don't be stupid like me and try to cut off the balance cable plug when the device is on. I unleashed magic smoke and now this unit is a strict bunker. I will probably order more of these in the future.
