I have an electric golf cart with 6 batteries, totalling 48 volts. The charger is a Power Drive 2. When I charge the batteries the charger reads 15. I charged my batteries yesterday for about 5 hours and the charger was still reading 15. Why is it not droping? Also my low battery light comes on and goes off randomly. It comes on and goes off even after I just charged it. When I first get on the cart the light is on, but when I take off for a ride the light goes off. Why is this? I also noticed one of the cables to one of the batteries is a lot warmer then the others. Don't know why. Thank You!
