[QUOTE="brian84corvette, post: 7074132, member: 586635"] that battery would work great if you upgraded your alternator also. something else to think about is... agm batterys and wet flooded cell type batterys. they tend to want to "rest" fully charged at diffrent voltages. my brand new deka group 31 flooded wet cell batterys all rest at 12.7 volts when fully charged even after sitting for 3 days after being un hooked from my charger ( I have 4 and I use them to power my hydraulics on my lowrider car ) - and I also have 3 group 31 size agm batterys - wich rest at 13.3 volts fully charged up - those are going to power my system when I finaly get the all the **** I need to hook it up... but - what im getting at is - if you hook up wet cells with agm cells and do not wire in a cut off - wether its an electrical relay or a manual switch like on a race car to turn off the battery - the wet cell will constantly drian voltage from the agm cell until they are both resting at the same level.... wich is about 12.7 or 12.8 volts while the car is running - the alternator is putting out power - and the voltage is suposed to be above 13.5 - so having the batterys rest at diffrent voltages does not apply when the car engine is running - and charging the battery systems - just food for thought. my setup when finished - is a kinetic agm 800 front battery - and 3 group 31 off brand agm batterys - all tend to rest at 13.3 so I will experience no drain off from them being permanently linked together.
