ok so i just got my vr2000d hooked up and i have a voltage drop way bad!! but i knew i'd have this when i hooked it up to a stock electrical system. so what i'm wondering my buddy has this batt thats sitting at 12.7 volt and it's been sitting for around 3 to 4 months. i asked him what size it is and he told me it's 100ah batt. so i'm wondering if this is a good batt or not? would this work good for a extra batt in the back?
