I just inherited an electric scooter - it appears to work well, but the
batteries are shot.
The "pack", if you will, consists of 2 x 12 volt 12 amp-hr 20 hr batteries
(6-MF-12 model made by YA HENG).
I believe the current equivalent battery is the UB12120
I know there is an EV "range" formula, but I cannot dig it up....figure the
scooter weighs about 50 lbs (max)...
Trying to determine how many additional batteries required to extend the
range of the scooter to a couple of miles or so.
