So I just bought a XS XP 3000 (120 ah)(3000 max amps) and I was wondering when I buy a second one for this 3,400 watt system should I replace it with stock one or just put it in the back with the other battery? What do you guys think is the best.. I already have 270 alt and big 3. (Side note) should I get another xs xp 3000 or can I save some money and just get xs xp 2000 (80 ah) (max amps 2000)
