If you have a 48V battery charger (not a 12V battery charger) then the negative off of the battery charger to the chassis of the car and the positive off of the battery charger goes to the last batteries positive terminal in the series hookup (4 batteries in series equals 48 volts).
Keep the setting on a low amperage (it takes longer but you are not hot shotting the battery and is better for them).
If you only have a 12V battery charger, you have to do each battery seperate from each other by disconnecting the wires on each one and then hooking the charger just to that battery.
I don't know if they make 48V battery chargers but years ago when I raced we had 16V batteries for ignition systems and the chargers for them were actually had 20V outputs. A 12V output charger will not charge up a standard 14.5V car battery as you need at least one volt over the nominal battery voltage for it to charge and also watch out on chargers that have high amperage outputs for quick charging or hot shotting a battery as they will damage batteries faster by quickly charging them and also some electronics in cars cannot handle the higher voltage that they also produce so it's best to disconnect the wires off of the car to where it is just the battery and the charger doing their thing.
