I have a 36v scooter, its a SXT Turbo
The scooter has 3 x 12v 12amh batterys to power it. One of them is faulty, i have 2 x 12v 7 amh spare, these are brand new.
Question is can I connect them up to replace the larger faulty battery? or can I not add the 2 new batterys in line to replace the faulty 12 amh battery?
