I've read a few things about using charging circuits and battery fuel gauges but it's a bit beyond what I know how to do right now. I might look in to it more in the future, or maybe someone else who knows more than me can add a fuel gauge to the schematic :)

I've used this which was very easy to get to work and there is C code out there to use with it. https://www.sparkfun.com/products/10617

Hmm, it seems like all the fuel gauges I can find are designed to be incorporated in to a bms, instead of being added to the input/output of an already existing bms. Do you know if there's a fuel gauge that can work with 12v so I can just add it to the circuit I'm using?
