I have a Freedom 3 wheel mobility scooter. It came with a 48V 2.5A charger. I think this charger is one of the cheapest on the market and don’t like the way it has to be used. It is a HENGGUANG MODEL: HGSPCHAONFE. I was instructed to use a house timer to control the on and off times because if you leave it plugged in you can overcharge the batteries. I was also told by the person who sells these scooters that there is no other charger that will work with this scooter. I just can’t believe that there is not a charger out there that will drop to a tricle charge once the batteries are fully charged that will work with my scooter. If anyone has or knows of a charger that will work better than the garbage I now have please let me know.
