Must of got some bad ones then... I have three of the spv70's and they are pretty good for the price... I have one im my living room to test out broken amps on and I have dropped it down to 11v before and a couple hours later I tested it again and it was right back up to 12.8vI would reccomend not getting Stinger batts, I used to run em and they dont hold a good charge for long
I guess It would work but I would like to have all the same batteries. I already have 3 of the spv70's.. But if worse comes to worse I will just get a diffrent battery and call it a dayWouldn't an Odyssey work? Or do you have to have that specific exterior casing?
