The factory forgot to solder the wires onto the PCB that connect to P-/B-. All you need to do is solder on your own wires and these will be good to go.

These are a 5 pack that come with 3ft balance wires for each BMS, bluetooth dongles, and the USB-UART adapter to plug it into your PC for programming.

We are selling these at a once in a lifetime price – as a result we are not able to offer warranty or support on these items.
