I'm using a small device called a BG-8s to check my cell voltages. This is made by ISDT. It can do several things, but I'm interested in its ability to check all the cell voltages at a glance.

I made the wiring harness from a JST-XH connector going to a 10-pin Molex connector with micro pins. This setup works because I have previously re-wired the inside of this battery. now the Molex connector is directly connected internally to each cell tab.

I've been thinking about installing one BG-8S on each module permanently and this is a kind of proof of concept.
