LiFePO4 Puzzle...

My apologies, I forgot that this was an off grid setup. When you always have some load on it therefore not the same as trickle charging.

You are correct in saying it is a bad idea to leave a constant trickle charge on an unloaded LiFePO4 cell though. Some smaller RV systems where there is only a tiny parsitic load may be an issue.
