Fusing high current BMS wires. Are there any pitfalls?
Newbie question here: is it a good idea to put a fuse between the battery and the BMS? Talking about the high current wires, the balance wires are self-fusing 🙂 In case the BMS develops an internal short there is nothing to protect the battery. I was thinking to put a 10A ATC fuse on the charge path and a 40A one on the discharge path of a 14S11P battery witch has a 30A BMS. But I am concerned that because of the voltage drop of the fuse the BMS will overcharge the battery / mess up the balancing / trigger low voltage protection too soon or ??? There must be a reason I didn't see anybody yet doing this. If you are fusing the BMS leads please let me know if you encountered any downside. Thanks for any insight you may have
