#9 LEARNING CURVE / HUMANS:
By far the biggest con for LFP is relearning the human behavior developed on lead acid. Voltage for SOC is pretty much meaningless with LFP so don't bother. You don't want to float LFP, unlearn float. Get out of the habit of "charging to "full", not necessary. Stop worrying about not being able to start your motor. Enjoy the piece and quiet and even at 80% DOD the LFP bank will laugh at the starter motor current. Starting a motor at 80% DOD for LFP is like Mike Tyson picking up a feather........ Unlearn your lead acid learning's and the transition to LFP will go much more smoothly. Human behavior learned from lead is IMHO one of the biggest cons for LFP..
