I have built a 10S battery back with a BMS that has separate terminals for charging (C-) and discharging (P-). However, since this battery pack will be used to power BLDC motors on a moving object it is important that the battery can charge and discharge through the same wires (when braking, kinetic energy from the motors is turned back into electrical energy to charge the battery).
I'm pretty sure it is safe to just connect C- to P- and treat it as one terminal. After all, it seems BMS boards with just one terminal are made this way. Before blowing up stuff I just wanted to double check with people with more experience, have you done this and/or do you know if it is safe?
