The nimble 4-wheel Merits Pioneer 5 DLX (S541) mobility scooter uses a pair of two 12 Ah batteries, but for more power and an extended run time you can upgrade to a set of 15 Ah batteries.
We recommend a 24 volt 1.5 - 2.0 amp offboard charger for this model. Choose a 1.5 amp replacement charger to maintain original equipment performance or upgrade to a 2.0 amp charger for faster charging time.
