Overkill, Thanks for appreciating our humor!
The 36v system as a whole is only a sum of its components.....
Therefore it is important to determine what condition each of the batteries are in and whether they are all matched or balanced ( the same)....
Most do this with a simple voltmeter and hydrometer.....
When all the 6 batteries are healthy and when connected in series readings as high as say 44v may be attained......36v would be flat ready for recharge. I hope this helps?

Ok thanks. My system is showing about 42v but the batteries are wearing down way to fast. I was wondering if their was voltage drop somewhere. I am getting only about 30min run time.

You may have a weak battery or two.....optimum run time is 90 minutes, 60 on old batteries. A hydrometer will tell the tale......a bad cel could cause this... How old are the batteries? what is stamped into the posts? Anything? What brand?

Scottyb, my cart runs all weekend on a single charge. I mean many hours.

I think your estimate is rather conservative....

Yeah my batteries are about 6 years old according to the numbers on the top posts. What is the average length of a well taken care of 6 volt?

Gorno, I could be conservative. I think I got those #s from Michael aka cartfixer or maybe Andy....now I can't be sure. Actual peddle time takes awhile to add up...But again I'm only repeating what I've been taught. Where is your stopwatch? Maybe you can check peddle time on the Z car?

The average length of a well taken care of battery is about 10.5 inches.

Then again, 90 minutes @ WOT (14mph) will yield 21 miles. They should go around 30 miles on a charge, so you're not that far off I guess. The keyword is PEDAL TIME.

Yes. Key word "actual pedal time"and age and condition of course.
