I just installed a Chins 400ah LiFePO4 on my boat. I have a Xantrex 2000XC inverter/charger.
Chins recommends absorption 14.6 and float 13.8v.
I have been playing with settings and researching for a few days now.
My issue is this:
When the charger gets to about 14.1v, it's builds to 14.2 quickly and then shoots to 14.5-15v instantly. The BMS cuts off and it drops back to 14.1. It keeps repeating this cycle endlessly. I watch the amps build and then go to zero.
Maybe the charger builds the amps to quickly?
Any thoughts?
