14s BMS on a 13s battery, can I?
#11
Test it and see. If not just ask for refund. Nothing to argue with the seller. The ad is wrong if it says 13s and you got 14s. Stop wasting time with messages back and forth and just have a refund request. Many sellers utilize that to just get more time and perhaps tire out people Smile

Just a little update on this, so I finally finished my battery and it turns out that the 14s BMS seems to be working on a 13s setup by just leaving the 14th wire disconnected. I still have to test further (discharging/charging through the BMS) but at least it's working for now.

Hello! A year has gone, can you share your experience? I bought same BMS, and have 13s4p battery. I tried leaving the 14th wire disconnected but BMS cut off the circuit when I connected it to a consumer. I also tried to short circuit 13-14th wires battery worked but didn't charge...

Did you make it work ?
