I recently bought a 1990 electric club car. It goes great on flat land in forward and reverse but as soon as u get on a decent hill it almost seems like you are going to have to get out and push it up the hill
Nature of the beast there. All elec. carts slow some on hills. How old are your batteries? There are some things you can do, convert to 48 volts, bigger motor, 4 gauge cables, etc. I would start by load testing the batteries.
