I like the idea Red, plus its simple. Ive read a lot about lifepo4 cells and I tend to agree with the 3.6 volts to be considered 100% vs pushing it to 3.8 or 4.0. The enginer kit stopped at 3.8 and many say that was too high. I think cut off was like 2.3 or 2.2, but that was on the low side. Either was for one cell and it triggered the system to stop charging or stop draining.
