Unless you have a Powerwise QE charger (Fins on case, no ammeter), the only damage it will do is not charging the batteries, which isn't being done at the moment unless you are using a different charger.

Plug charger into cart without plugging it into AC power.
You should hear a relay inside charger click.
If not, unplug from cart and plug into AC power.
Nothing should happen, but if transformer hums, the relay has been bypassed and charger needs a new control board.

If you did hear the relay click when plugged into cart alone, unplug from cart and plug into AC power.
Then plug into cart.
After a short delay, the ammeter should jump to 15A-20A.
The ammeter may stay that way up to half an hour or more and than start tapering off, eventually getting dow to about 4A or less and stay the way until the on-charge voltage climbs into the 44V to 46V range, at which point the charger shut shut off automatically.

It being the initial charge on a new set of batteries, it may last 12 hours or more.

Even if the relay is bypassed, the charger can be used to charge the batteries, you just have to shut it off manually (unplug it) when the on-charge voltage gets into the 44-46 volt range.

The actual charge profile is built into the matched Ferroresonant Transformer and Capacitor design and all the control board does is turn the charger on and off based on the pack voltage.
