Re: no power going up inclines
Nailed it! All batteries are weak, two dropping below 3.5 volts on the hill. Total recovered voltage was 30.1 after testing each battery separately. I never thought about load testing the batteries under actual driving conditions. My crappy little hand-held load tester had me thinking in other directions, but it makes sense that a tiny little load tester can't sufficiently load a golf cart battery.
Thanks! I'm off to buy six new batterie$$$......
