Hauled the Diehard booster out and charged that low bat at 14.7 about 3 hours. Charge charge charge re charge. Pretty annoying.

I am getting to the point of buying 5 Diehard chargers, put them in 1 box (like an octopus with wires instead of legs; and charging all 4 (48V to 56V) at once, instead of spending a whole day charging.
