I got tired of opening my enclosure to charge lipos and ordered a bms I intend to use for charging only. I started looking at some wiring diagrams and got kind of confused. I bought the following cheap BMS without much information: https://www.ebay.com/itm/222272460111.
The only pads I am seeing are B+, B- and P-. I see most other BMS diagrams feature a C or CH port. Is this bms good for discharging only or should I connect the battery ground to p-?
