Batterie problems any ideas ?

[LYN-HOS]

I have 7 batteries (Optima blue tops. I used to have Odyssey till they went bad) with an on board charger and charge every night but toward the end of the day my amps start shutting down due lack of juice (not cause they are to hot ) . IÂ’m sure you guys with the big stereos have this problem figured out ??? IÂ’m considering a generator or golf cart batteries. I would take all the advise I can get on this matter. Thanks Dave

Sounds like a generater is in your future. I hear Car Toyz in Lake Havasu is the place to go.
That's all I can offer.
