Batteries Gone Wild
 

Let me start by saying I have a 2000.5 Club Car 48Volt Regen2 with an Alltrax DCX 500Amp controller and Interstate Workhorse batteries that are about 3+ years old. The problem started two days ago when i drove the cart for about 10 min. ride it started to shudder at high speed, the cart was slightly faster than normal so i figured something was definitely wrong. I got it back to the house and the motor was HOT, i could touch it and not burn my hand but it was a quick touch. I failed to get my temp meter out at the moment and temp it as it was getting late. So yesterday I scoured this site looking for answers. I'd narrowed it down to a possible voltage or pack issue. So i got home last night only to realize all the batteries were low on water and the pack was sitting at slightty over 67 volts....YES 67. So I ran to the store, got distilled water and filled all the batteries to spec. I let it sit over night and checked it this morning. Now the pack is sitting at 83 volts. I'm positive that's not good.....Question is, What do I do about it? I've figured out that the water was low and I put a full charge on the pack thus creating this issue.

I have never heard of this happening? Try changing the battery in your meter.

I will try that when I get home tonight. If it is over charged that high, any ideas? Last night when I metered them my 8Volt batteries were sitting at 11+ each. Thanks for your help Scottyb

Or try a different meter all together....:?

I think i'm going to head over and buy a new one this morning just to avoid any and all confusion later this afternoon. Hopefully that fixes the issue. :thumbup::thumbup:

I have a few meters, 2 are good Fluke meters. They will confuse the hell out of a technician when the battery gets low.... which it does because I'm constantly leaving them on and walking away ...

So I just got home with my new meter am tested the pack again....... 49.7V and each battery is around 8.3 or so. Thats after about a 12 mile ride up and down some pretty decent hills loade with 4 people. So let's now move on to what might have brought on the high speed shutter and HOT motor. Any ideas? Let me throw this in there too. At half throttle it shudders the same way all the time as it did this one time at high speed. Normally I can cruise slow, then half throttle it shudders if I hold it there, then it's perfect on full throttle. But that one time it did it at full throttle too.

what solenoid do you have?

Re: Batteries Gone Wild
 

It's 400 continuous 1000 peak heavy duty.

I'm charging the batteries now to see what happens on a full charge. I have a theory.

I'm also running all #2 gauge wires to all batteries and motor.

The batteries were low on water and I charged the pack. The charger shut off giving me the assumption it was fully charged when in reality the batteries were probably low. I drove the cart thus dropping the voltage even further producing the shuddering, since the controller and motor were starving for volts the motor got HOT. Having a broken meter I was unable to check what voltage was. So when I filled the batteries with water and let them sit it brought them up to 49 volts which is not a full charge. When I drove it tonight I shuddered slightly at high speed but the pack was only at 49 volts. Sound logical?
