Mobility scooter questions

As for mobility scooters and batteries, generally they will use a pair of 12 amp/hr batteries, or a pair of 18 amp/hr batteries, or a pair of 35 amp/hr batteries. They are wired in series for 24 volt operation. I would suggest 18 amp/hr batteries as a minimum for better range. These devices have user weight ratings, and if you approach or exceed the weight limit, the performance suffers. At the maximum weight rating, they will perform and operate, but not near as well, especially going up grades. Also, in very hot weather and demanding driving conditions, many power controllers could go into a thermal roll back (power reduction) sooner if the unit is loaded to the max. I believe most of the main line brand names are well supported by their makers. Purchasing from a reputable dealer would be just as important as which manufacturer you choose. I don't know how well an online dealer can support and remedy a defective unit compared to a brick and mortar store. Mobility scooters are like most mechanical devices, they either run or don't run! Good luck!
