club car problem

mhandley

I have a 91 cc just changed the battery pack and now the cart acts like the batteries are dead. I have tested the batteries and all of them are reading 7.1 to 8.0 and I have 47.8 volt from the pack. What else do I need to check?

Put a full charge on the batteries. New batts are not at 100%. When the charger turns off, wait 12 hours. then read the pack voltage.

Yes, you need to charge them. You've got dead batts now...

Each battery should measure out at about 8.6 volts (or so) fully charged- and the pack should be reading out at about 51.6 volts... Are these batteries brand new? They may still need to be "broken in". I'm pretty sure a search on this site of "breaking in new batteries" will yield some pretty impressive results. There are many VERY informed users of this forum. Best on the 'net as far as I can tell!
Basically, after 5 or 6 good charge/discharge cycles, your batteries will "flower" (I made that term up ). Don't quote me on this, but I believe it has to do with the "etching" of the plates inside the batteries which are smooth when brand new and gain surface area as they get further broken in. Like I said, don't quote me on that one...
After a few good discharge/charge cycles they should come to life nicely! I wouldn't recommend going below 75% SOC (State of Charge). Taking your cart out all day and limping it home on dead batteries (@50% SOC) is never good for the batteries- be it during the break-in cycle or not.
Hope you get a good Flowering!

ThNks for the advice. I was worried about pulling to have on the drums and breaking something. I'll pull like hell on them. To get em off

Thanks for all the help. I got new batteries well new for me LOL there less then a year old Trojans. Now the problem is when I go full throttle one cable or motor starts to smoke. If you easy around on it there is now problem. What might be the problem. I have checked the cable connections to make sure they are tight, cables are hooked up right. I do have a 500 amp controller and heavy duty f&r switch, solenoid, 4 gauge. Didn't have this problem before new batteries.
