Another Club Car Ds charging question.
 
I search and searched but couldn't come up with anything, so here goes,,,,,

I just acquired 1999 golf cart. cart has been recently refurbished, very clean cart that came from a knowledgeable owner.

I bought new batteries but didn't check pack voltage before my initial charge. after the first charge which seemed quick did and i got 51.1 total pack voltage and all individual batteries were 8.51 or 8.52.

no matter how many times i put this cart on the charger it turns off so i cant get it above 51.6 = 80%.

when i pug in the charger there is a click then a pause then it starts charging at 15 amps but quickly goes down to 10 amps then 5 amps and turns off. that whole process take probably 20 - 30 minute at this point. i did put my meter on the pack when is was charging at 10 amps and pack voltage was 60 volts.

The charger I'm using is the club car power drive, pretty sure its the first generation.

Any help would be greatly appreciated.

Looking at the chart I have for a 48 volt pack 50.9 is 100%

I am far from an expert but have been following these forums for a while now. That problem sounds like the OBC is not commanding the charger properly otherwise the charge cycle should be longer for sure.

Even with that charger you can try to bypass the obc and use that charger manually from what I understand. You will need to monitor the charge as it won't turn off on it's own.

If that does work then you can decide whether to get another obc or a new charger. Again, most of the folks here choose to replace the charger with a smart charger when faced with this choice.

Sounds like everything is working as it should. What pack voltage are you trying to achieve? You're already above 100% - IF it's a 48 volt lead acid pack. The charger is shitting off because the pack is full. The PowerDrive / OBC combination shuts off based on reaching a preset voltage.

Maybe for some lithium pack sold as a nominal 48 volt replacement?

Make sure the negative cable from the battery pack goes through the hole in the OBC.
Full pack voltage for a FLA pack should be 50.9 or a little more about 12 hours after the charger turns off.

The pic above is for a lithium pack. 13S = # of cells in series, which is probably for a home-built Volt or Leaf pack.
