do you have it set on AGM High?
When it gets warmer, your alt will put out less voltage, metal properties
I use 25 amp
I just always leave the charger on until I need them, that was a week strait for my 16v
The charger is a 3 step cycle and you should wait it out until the float stage
Ya Ed Lester has a sick install with 10k+ watts, 9 small batts and stock alt
I still have my stock alt, with some extra batts I can keep voltage around 12v
I have a panasonic CQ-VD6503U 6.5 in double din DVD, comes with cage wiring harness and a brand new remote $325 shipped
I dont have many if any posts here, but I am a member on the caraudio forum, ROE, and the DB Drag racing forum
