you want to wire the batteries in series...connect negative of one battery to positive of the other. You then use the two remaining terminals as youe - and + 12v source
Connect two 12 volt batteries in series and you will have an output of 24 volts.
Connect the two batteries for the voltage needed. If they are 12 volt batteries and the lights are 12 volts, connect the batteries in parallel (negative to negative and positive to positive). If they are 12 volt batteries and the lights are 24 volts, connect the batteries in series (negative of one battery to positive of the other). Run a wire from batteries to first switch, then to two of the lights and the other switch (in parallel). From the second switch run a wire to the third light, then connect all three lights back to the battery.
You would connect two 12-v batteries in series to get 24 Volts, but if you have four, you can connect two sets of batteries in parallel and then connect the two sets of parallel batteries in series, giving you 24 volts with twice the ampere-hour capacity (four batteries rather than two).
connect its two terminals with a wire.
Connect two 12 volt batteries in series and you will have 24 volts.
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.
Yes, 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.
amps
yes
you only need two 12 volt batteries to make 24 volt. connect them in series
In order to connect 4-6 volt batteries and end up with 12volts you will need to understand parallel and series connections. to connect two batteries in parallel you would connect the positive side of one battery to the positive side of the other battery; and the negative side of one battery to the negative of the other battery. doing this will not change the voltage. to connect in series you connect the positive of one battery to the negative of the other battery. doing this will increase the voltage;in this example you will end up with 12v. 6+6=12. when you stack batteries in a 2-cell flashlight that is connecting the batteries in series. The answer to the question is: connect two batteries in series; then connect the other two batteries in series. after this is done connect the two pairs of batteries in parallel. If you think of it visually you would have two batteries wide and two batteries tall.
