LIFePO4 batteries - interesting challenges
In another thread I detailed what I was doing to upgrade batteries to LIFePO4. Thought I'd raise a new thread for some challenges I'm facing in case someone searches on it in the future. I have 4 1...

So, for shore power I think I have it figured out.
Similar but different issue - I have 2 victron MPPTs going directly to battery bank (from different arrays). In bulk charge they work fine, I get to 100% (14.4V). However they then go into standby waiting for the voltage to drop to the threshold to kick back in on bulk charging, which you guessed it is when I'd hit around 20% SOC (12.8V), I don't want to draw that far down.
Any harm in setting float voltage on the MPPTs to something rather high (say 13.5V or even higher?) to keep the batteries topping up during the day. This obviously would not be a problem after sunset, and would give the batteries a chance to draw down overnight. ?
