I got back to tinkering with this project the other day. I changed up the face too plate a little. I like it a bit more.
I still need to set the charge controller correctly. I overcharged the pack the other day to just over 4V. Lifepo4 is not supposed to be charged that high. I'm thinking I should hook up the dc-dc converters to some power supply and tweak it that way. I also have to swap out the resistor so it can charge at 5A vs 2A.
