This is what makes me think that the old golf cart bats are still the bets bet for us poor foke 6v 100 ah is not pushing them .yes they are 1/3 heaver but looks like 2 times the out put power and 1/3 the price . I will probable go back with golf carts bat in my Porsche when the last 12v 31 deep cycle gives up its last amp hour . I'll let these with the big buck burn the wheels I just need to get were I'm going ( . I think I got 20 k on the Mercury lynx 6 v and drove 30 miles 60mphs on 75 ah . ) I know you don't want to redesign your car for golf cart bats and maybe driving slower is the only answer along with plugging in places .
