I'm planning on building a diy battery out of 18650s, which has a BMS, for a Onewheel. The voltage will be 63v and max load +10A so it will be 15s. There will be an XT90 where the load will be connected and I want to have a separate charging port.
I want to prevent shorting over the charging port pins, if dirt or mud gets in it. What kind of diode do I need or how would a mosfet be wired if I were to use one? I've tried Googling a lot but really hard to find anything specific. And I dont want to use a 3 state switch that has modes for use and charging.
