My jbd smart bms sp24s004 is not detecting charger/ battery so not showing any voltage of 16 cells. There is a one charger detection port on bms but I am not able to understand where these two wires will be connected. Any body if knows please help

 

Probably explaining what you are trying to do will help. AND, because many folks here need an actual circuit, also provide a schematic drawing, not a wiring map. THAT will lead to a lot more resonses.

 

Connect detection wires to charger's positive and negative terminals for BMS to detect it.

Thanks a lot
