Bismo1999, I am sorry about that, when I read your post I read
30 miles not
30 minutes. Quite a difference. I must have been having a bad morning as you also said US2200 which I now see is a 6 volt battery. I could not have been drinking at 10:14 AM could I? Lets see if I can do better today
. Here is what I would do if it were my cart..
First thing I would want to know is if the batteries are charging properly. I should be able to check with the multimeter. I would make these notes:
Time since last charge:
Voltage of battery 1,2,3,4,5,6,7,8, pack
Put on charger, verify charger comes on......
Document time charge started.
Take voltages periodically during charge, especially as we get to the end of the charge cycle. Each battery should be pushing 8 volts toward the end of the charge, mine get to around 7.8 volts, pack 63 volts.
Each measurement document time, voltage of battery 1,2,3,4,5,6,7,8,pack
This will indicate if the batteries can take a charge or may indicate a battery that is not charging.
