This is my theory on a 24v 24ah system.
I have three 6v 12ah batteries I pick up from Guber Battery Supply for my girls modified power wheels Jeep.
Well they have a motorcycle now and no need for the power wheels so I was trying to figure out if they would work in the Oset. With three in series, 18v doesn't do the trick. But I used two 6v and one 12v, this still only leaves me with one set of batteries. I don't like this set up because of the difference in ah's.
Did some digging on electricity and took some measurement and four 6v,12ah batteries will fit.
So, hooking two batteries in series gives me 12v,12ah. With four batteries I have two "packs" of 12v,12ah. If I hook these two packs up in parallel I get one 24v, 24ah system.
Well is this safe you ask? The motor is rated for 24v, and 36ah so no issues there. Could I cross some wires, yup. Need to be careful on initial hook up. No issues with charging or dangers after that initial electrical spaghetti. And weight gain is about 4lbs so not extreme.
My conclusion is more than double the run time for a $13 battery, SWEET!
Anyone see any flaws in my logic?
