Re: lack of power
You can do a load test by hooking your voltmeter to the batteries and then driving and then tellus what the voltage is doing while driving. You can tell the age of batteries by olloking at the battery post the year will be the # on the post anfd the month corrisponds withe the letter.

Re: lack of power
still don't have any power! i put my volt meter on it and drove it around it's setting still and the lowest i got it to go 35 and that was going up a good incline. i charge it up over night and the next day it did not have any power and the battery meter on the cart goes down half way when i drive it! could it be the controller??

Re: lack of power
sounds like bad batts, i believe i heard on here that pack should never get below 36, 36 is considered dead, if i am correct, think i have a batt chart, lemme look!!

Re: lack of power
That's to determine state of charge at rest, not under load. 35V under load is actually quite good. My old batteries are getting down to 33V under heavy load..
