Ok, I took some clip leads and drove the golf cart last week with the following results
1 Pos and 6 neg was 49.9 fresh off the charger (I know the math below doesn't equal the 49.9 when combined)
1 After charge: 8.17, driving 7.9
2 After charge: 8.23, driving 7.8
3 After charge: 8.27, driving 7.8
4 After charge: 8.3, driving 7.9
5 After charge: 8.25, driving 7.8
6 After charge: 8.17, driving 7.7
The chart was still way under achieving, sometimes stuttered and felt like small hills were impossible.
But the weirdest thing happened last night, my son asked if we could go for a ride and I noticed the cart was at 58.9 on the charger. So I took it off and started driving, its like its back to normal power. WTH?!? I am at a loss, I was 100% convinced it was the batteries, now I am worried it could be something else. Can anyone tell me if there are a few other things besides batteries that could cause this?
