as scotty said you have the wrong batteries in your cart

no i found out it is a 48volt cart and i put in 6, 8volt batterys and it looses power when it set over night

ok
are the batteries new or used ?
are all connections clean and tight ?
this will take a few days to get readings
take readings of battery pack and each battery before charging
charge cart till charger shuts off , this can take up to 16 hours , take voltage reading of the battery pack and each battery
wait 12 hours take voltage reading
24 hours take voltage readings
36 hours take voltage reading
post all readings here

It may be that the 8 volt batteries are tractor starting batteries. I've seen a cart with those in it
