Single Port BMS MOSFETs Explained

Tags: Electronics, Solar

I'm writing this post since it seems there seems to be some confusion on why both MOSFETs in a typical single port BMS (Battery Management System) are controlled individually and why/how this works when they're in the same series circuit. It will hopefully also show why just controlling both MOSFETs at the same time to try and accomplish this is not a good idea.
