Confusion on battery charging
I am confused about the best practices for charging batteries. For 7 years I had 300 AH of Lifeline AGM batteries, 270 watts of solar and a simple charging system. My old camper has a 110 volt c...

My controller is the Blue Sky 3000i. It is functioning according to the manual. The solar panel can be at absorption of 14.3 with any amount of amps needed to maintain that voltage. If the panel output is interrupted and the battery cannot maintain 14.3 volts, the controller will revert to bulk mode. When it returns to 14.3, the absorption mode clock will be reset to 2 hours which is default or to whatever time I set.
Right now I am getting 10 amps out of the panels and the voltage is at 13.6. My old controller would have dialed down the amps and maintained 13.6. My new controller will be pumping maximum amps into the battery for the remainder of the day. Since my old batteries performed well and lasted for 7 years, it just seems that they are now being overcharged and will die prematurely.
Mex... so far I have not seen the level of charge you recommend. The lowest amps I have seen is about 4 or 5. By then charging typically enters float or I cycle back and forth but still never drop below about 4 amps. I guess that means I don't have a problem with overcharging the batteries.
