Now I have ordered a second Maxxima (so I have two Maxximas in the trunk, but not in the front as standard). Now I have thought if I should just hit my serial battery in the trunk (should finally operate a Colossus XI). But in an old thread I have read that one should use only the same batteries as possible, because otherwise they would unload each other (through a different internal resistance). However, many of them have below What’s right now? Can I add my old battery? The space is there and the few kilos that weighs them don’t interest me either. So if that even adds something, I’ll put them in with it, but if the batteries then discharging each other, of course she stays outside. So, what do you think? MfG, Diddy
