I am not using voltage as a low charge indicator. I'm aware that that is a horrible way to do things. If that were the case I also would recommend bottom balancing, but it is not. See above for how I am detecting the low charge.

So, I will be setting a conservative number to get ~70% DOD on my weakest cell and once that cell hits 70% DOD it will turn off the PHEV kit.
