What ? A 48V electric cart normally has 4 - 12 V batteries interconnected. You can charge them one at a time if need be.

Actually I have seen 8 6 volt batteries, and 6 8 volt batteries, so care must be taken to use the correct charger, if trying to charge individual batteries.

Translation of what people are telling you in original post. I assume you have lead acid batteries but it almost does not matter.

Some say my cart is 48 volts. That is true of many carts. Then you hear it is 6 -8v batteries. It can also be 8-6v batteries or 4-12 v batteries. They all equal 48 6x8,8x6,4x12. Each of those batteries is a pile of cells, each cell, lead acid is 2 volts.

You are not supposed to run the batteries all the way down. One cell will always be weaker than the others. When you run the battery too far down the stronger cells will reverse the polarity of the weaker cell and destroy it.

Sometimes you can have someone put a too high voltage charger on it and make it TEMPORARILY work. It is only a very short term fix.

You want to take your charger into a shop and have it checked to see if it is working properly. If there was a short in your battery it may have damaged the charger.
You will likely need to replace the batteries. There is a date code on your batteries.
Will be endless posts. Lead acid batteries, life is 4-6 years.

Those suggesting charging one battery at a time. If, you measure it you will find the charger puts out a higher voltage than the battery. To get current to flow into the battery you are trying to charge the charger must be higher voltage than the battery. A 12 volt battery and a 6 volt charger the battery may well destroy the charger or blow a fuse, a circuit breaker etc. You can buy a 6v charger for cars.
Many be hard to find. Six volt systems were used in antique cars. I think my 64 VW was 6 volts. There are chargers that have a switch 6v and 12 volt. I expect there are 8volt chargers, I've never owned one.

More confusion as posted by me 48v and how you get there 4x12=48, 6x8 is 48, 8x6 is 48.
Why use 6 or 8 batteries when 4x12 is 48. That answer is total capacity, ampere hours.
You can perhaps think of it as a bucket of water or even a gas tank. A bigger tank will go farther.
