No, since in series they are 24 volts so you need to charge each one independently with the 12 volt charger. This may be done disconnected or leave them connected and put the charger on the + - of the same battery.
12kv is equal to 12000 volt.(12*1000).
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.
depends on the voltage of the batteries.. four 12 volt car batteries would output 4x12 = 48 v
I would opt for the two twelve volt batteries in parallel. This configuration will give you the voltage that you need for the system to properly operate plus the endurance time that you can draw from the batteries will be doubled. The amp/hours capacity of batteries when in parallel are additive.
Connect three 12 volt batteries in series. You will triple the amperage but the volts will remain at 12. Click the link

Modern automobile batteries are 12 volts.
they are 12 volts
When 20 12-volt batteries are hooked up in series, the result is 240 volts, measured from the farthest ends. When 20 12-volt batteries are hooked up in parallel, the result is 12 volts (while current increases).
Depends on the battery size. If your boat is a 12 volt system and you wire two 12 volt batteries in series you then have 24 volts. If the batteries are 6 volt batteries you will be fine. If you have a 12 volt system on your boat and want to use two batteries then wire two 12 volt batteries in parallel. You will still have 12 volts but will have double the amperage available and this will extend the running time of the batteries.
NO!
Two 24 volt batteries in parallel will give you 24 volts. The only other way is two 12 volt batteries in series.
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.
Paralleling four sets of 6 volt batteries will still give you 6 volts. Two 6 volt batteries in series will give you 12 volts. Parallel these series sets will give you longer endurance at 12 volts. There is no way you will ever get 48 volts out of four 6 volt batteries.
You will have a 12 Volt source with double the charge capacity.
That is Impossible. You can however make two 6 volt batteries into a 12 volt system by wiring the two 6 volts batteries in Series. You will then have an output voltage of 12 volts but the amperes will only be what one of the batteries have, In other words the volts will double but the amps will stay the same as if you only had 1 battery connected.
