Ok, so I know there are a lot of factors here. First of all I am driving a 94 VX with some mods and getting about 60mpg. My battery has been slow to crank and after further investigation it seems it's due for a new one . . . hmmm, deep cycle . . . no alternator. . . tempting
So I think I found a place I can pick up some decent used deep cycle batteries at a good price. Then I need a charger and a way to monitor voltage. But I am wondering what kind of range I can get with out an alternator. I drive 50 miles to work and 50 miles home. Usually won't need headlights, also considering led headlights. But I will need to run a/c a good bit as the summer heats up here in GA. I also have one 10 inch sub with a small amp, I can live with out if I must, but would rather use it at moderate volumes.
I am hoping that 2 decent sized batteries in the hatch will be enough. Maybe even one more small one to replace the original battery. What can I expect, and is it reasonable to still use stereo and sub?
