The charger will work just fine, the charger knows at what voltage to turn off by itself, your cart is pre 1995 CC 1st yr 48v OBC, I have a powerwise with the crows foot just for that purpose.
I remember it didn't work immediately I had to switch a wire in the charger to get it to read the CC.
I may have to open this charger again to see what I did? It's been awhile......
