Hi everyone, I am designing a PCB that is going to be powered up by 2 x 18650 LiOn Batteries connected in parallel. The batteries will be placed into a battery holder, so the user will be capable to take them off in order to charge them. I want to integrate a reverse polarity protection mechanism on the PCB to prevent any damage from reverse polarity (that will short out the batteries). I am thinking to place two n-channel MOSFETs on the positive side of each battery like the circuit below. What is your opinion? Do you have to suggest another solution?
