Without question carring the battery weight up high is a problem. Maybe you could try using a Currie Ezip/Izip battery rack. I don't know if you would be able to mount it or not but if you could it would drop the weight down and be more stable for you. You would also have to make your own cases to fit the cells into to mount onto the rack. You would put 6 cells on each side of the bike. I carry 8 cells on each side of this same rack but I am riding an Ezip bike. I made the battery cases our of plastic so I know it can be done. But no matter it is still a good idea to change to a double leg kick stand.
