well i got lots of hills round here! are you saying hit the hills on a full charge and log realtime voltage? then log readings/rested after as well? how long do i do this load test?
thanks

I'm just saying use the cart as the load tester. Begin with a fully charged cart. Take voltage readings atleast 1-2 hrs after the charge cycle has ended. 6hrs after is fine too, just not right after charging. You'll get falsely high readings (like your sg readings) if taken too soon after charging. Clamp bolt or tape the meter ends firmly to the pack ends so it reads the pack voltage and go climb some hills. Take paper and pen with you. Record the starting voltage & while climbing a steep hill and your foot to the floor. Let us see how far they are dropping Drive it for 1/2 an hour and do it again. how much lower the second time? This will give you a good look at your battery condition

It is important that the MCOR is working in order for this test to give correct results

Ok Ill go through the official MCOR test procedure tonight. Ill have the results up here tomorrow morning or later tonight.
Thanks I really appreciate the help!

Ill then do some load testing tomorrow and post those results as well.

I did the above MCOR test and my result for question #2 using a multimeter was 51.5V or the full battery charge. I went on to the next step question #4 however I could not continue due to no "white wire" on my cart. For grins I tried all the other wires and got nothing even close to the correct reading of 4.65V.

I rigged up my l.e.d. datel onboard voltmeter for viewing during tomorrows load testing. What voltages should I be looking for or not looking for?

Thanks

Default 1st 1/2 batch of load data:

start at 2:47 @ 51V
end at 3:19 @ 49.6V and gaining
total test time 32 minutes

2:48
hill steep/wot= 48.2V (This is a very steep uphill for 1/8th mile then not as steep another 1/8 mile)
cruise slight uphill WOT= 47.3V
cruise slight downhill WOT 48.5V

Note same loop as above repeated with following times:

2:53
47.2V
48.2
48.6

2:56
47V
48.2V
48.5V

3:00
46.9
48V
48.4V

3:04
46.8V
47.8V
48.2V

3:09
46.7V
47.8V
48.2V

3:13
46.6V
47.8V
48.1V

Thought on load data?
Thanks

Prior to first load test I took the SG data again approx 12 hours after charge:

starting pack voltage was 51V

#1, 8.53V, 12.77, 12.70, 12.75, 12.75
#2, 8.54V, 12.90, 12.80, 12.85, 12.85
#3, 8.55V, 12.75, 12.85, 12.76, 12.85
#4, 8.55V, 12.80, 12.80, 12.85, 12.85
#5, 8.53V, 12.85, 12.80, 12.80, 12.85
#6, 8.51V, 12.80, 12.77, 12.77, 12.75

I understand some of my reading are reading to high/good. I am just reporting what my AZ temp comp hydrometer is reporting.

Thanks
