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...

This is how I have mine set..
The following parameters are for programming the ME-ARC Version 4 advanced control.
LBCO Setting: Volts = 12.0
Battery Type: = Custom
Absorb Volts: = 14.2
Float Volts: = 13.6
EQ Volts: = 14.2
EQ Done Time: = 0.1 (I don't use EQ)
Absorb Done Time: = 0.1(I can't turn this off)
Max Charge Rate: = 100%
Final Charge Stage: = Float
I have not gone over 14.2 on my setup the % capacity resets/ balances the cells at that voltage.
Most drop ins require 14.4-14.6 occasionally to reset the % capacity/ balances the cells.
For your summer style with the camper I would use these but you can go with a bit less but you will have use 14.4 occasionally.
The battery guy said I was fine at 14.4, the cells reset at 14.6. Thanks for the info.
