    Optimizing Battery Performance for Increased Power in Automated Wheelchairs

    For a physics project, we have to increase power to an automated wheelchair. This wheelchair has: Battery Capacity 2x60AH Battery Needed (x2) GR 24 I know that this means there are 2 batteries at 60 Ampere-hours. I don't know what a GR 24 is. Also, I don't know how to increase...
