Lifeline Battery Recovery experiences?
I had a thread about our Magnum MS2812 going into Fault code mode overnight while boon docking. Posted under Magnum because I first thought I may have had a problem with my program parameters, and pos...

800 AH you need 160 amp charge current to meet the 20% of capacity recommendation from Lifeline for deep discharge bulk charging. I had a similar setup on our prior coach, and noted some symptoms of early voltage drop under load after a lot of shallow discharges and slow solar recharging.
I had a marine battery selector that allowed me to divide the big bank in half. I found that by halving the bank, drawing the smaller bank down to around 50% and then vigorously recharging with my converter (at 27% of C) they got stronger each cycle. Voltage drop took longer under load and charge acceptance increased.
I also periodically top charge them and use a precision ammeter to ensure I get them to the 1/2% spec.
