How to Convert a 24V scooter to 36V - Dirty Method

Step 3 Charge Batteries

I used the 3 12 volt gel cells from the 36V scooter for this hack - the 24V sulfated pack will be desulfated at a later date. These need to be charged. I charged them on a 1.5A "smart" charger using a multimeter and an ammeter to monitor progress. This is a proof of concept, and a rather dirty hack -- so things are twisted and clamped together.
