you only need two 12 volt batteries to make 24 volt. connect them in series
connect the 2 six-volt batteries together one terminal each positive to negitive, this will make a 12-volt combination, then you can connect the jumper cables, one side to the 12-volt battery and one side to the two 6-volt terminals, + & -
Connect three 12 volt batteries in series and you will have 36 volts but will only have the amperage of one of the batteries.
If your cart has 4, 12 volt batteries in series to make up the 48 volts, just connect the 12 volt lights across one of the batteries.
Connect them in series.
Assuming the truck has a 12 volt system, connect the batteries in parallel, that is positive to positive and negative to negative.
Connect two 6 volt batteries in series. Connect the other two 6 volt batteries in series. Now connect those 2 pairs you have together in parallel. You will end up with 12 volts.
No. If you connect two 12 volt batteries in series(positive to negative) to make 24 volts, you will have 100 amp hours. If you connect two 12 volt batteries in parallel(pos to pos, neg to neg) you will stay at 12 volts but have 200 amp hours

Connect 2 of the 6 volt batteries in parallel and then connect the other 2 in parallel. Now connect those 2 pair in series to each other. You will now have a total of 12 volts with four 6 volt batteries connected in parallel/series. Click the link.
If you have two 6 volt batteries you can take a jumper wire and connect the negative post on one battery to the positive post on the other battery then connect the remaining pos and neg posts to the 12 volt battery charger.
You will have a 12 Volt source with double the charge capacity.
You can connect batteries with different voltages in series (a 6 volt and a 12 volt would give you 18 volts), but never in parallel (difference of potential will create an arc, batteries could blow up).
