I have been charging my life chins 12v 300ah lifepo4 battery With my newly installed renogy DC to DC charger. I have a 200 watt panel up top and a switch to turn off the solar to maximize my alternator charging. My question and confusion comes from Seeing my battery at 12.8 V or lower before charging. I start charging at max of 50 amps my battery will top off like pretty fast within a few minutes and cut off my current and start boosting. I'll adjust the charging down to 40 amps or even 30 and it will eventually do the same thing even though I know my battery is not that full. Why does this happen? Is there something wrong with my battery or charger? I'm always adjusting the charging even switching on and off the solar for combined charging of 20 amps which seems to work but I want To get maximum efficiency and wondering what's going wrong. Can anybody help me put on this one? Any input would be great thanks
