I don't believe that charging batteries in series is the best choice. If you're going to charge the batteries off board anyway, charge them individually or charge them in parallel with a 12V charger if they are the same capacity and same age.

There are battery balancers you can buy in order to charge them, but I think it's likely to be pseudo-science, or more expensive than a 12V charger. I'm not convinced there is really such a thing as balancing batteries for household or vehicle applications using plain lead-acid batteries.

Did the original charging system built into the scooter fail, and that is why you're trying to do something different?
