Polarity protection would be amazing on this. just burnt out a board because the battery manufacture miswired one of my batteries. My fault for not checking all of them but it still would be nice

It would be nice if it had reverse polarity protection -> I accidentally broke my first one because the battery I bought had the plug mounted incorrectly. Fits perfectly also on my RPi zero 2w

First I thought, why would I use it. But now that I had it for some time, I find it very useful for various types of applications. Only thing that I don't like is that will drain the battery if its left connected to the board for a long time.
