un hook the batteries hook a jumper from one battery + to the other batter - the ground wire goes on the one battery and positive lead goes to the other. Series hook-up.... but that's a 12v charging system trying to charge 24v good luck with that.

If you add + to - that will give you 24 volts. Right?

yes it will or you can just hook the positives together and negatives together like below.



Parallel wiring-- keeps the voltage the same but the battery bank (2 batteries) will provide longer lighting.

Series wiring -- doubles the voltage but the AH (amp hour) remains the same.

By using a jumper from one battery positive to the other batteries positive and the same thing with the negatives, this will hook you up parallel. You will still have 12volts. (See the post by Moose)This will cause both batteries to have the same charge. If one is being charged it will also charge the other. The problem is if your charging system doesn’t put out enough, both batteries will eventually go dead. Another problem is if one battery is weak it will weaken the other. As long as the charging system is adequate and both batteries are good you should be ok.
Hope this helps.

All the information here is accurate, but you do not know how much current the charging circuit will supply.

You could hook up 2 smaller batteries and it would work fine, hook up 2 larger batteries and try to charge them and you run the risk of overloading the charging circuit, which would A. fail to charge the 2 batteries, or B. SMOKE.

I wouldn't answer the question without more information. On paper, it works. In practice, the possibility of SMOKE would prevent me from trial and error.

In electronics, always try to prevent releasing the magic smoke.

Agree^^^^^^^^^^
There are companies like Ricky Stator that do upgrades the charging systems.
That is what I hear.
rickystator.com
They may head you in the right direction or give you an idea of where to go.

Ricky Stator is who all of the Baja guys use to power their headlights for the night portion of the races. And we're talking big arse dual 8" halogens!

i dunno id just have to hate to recharge a battery after every ride that will kill the battery fast wont it
The thing about creating 24 volts on a 12 volt system is going to cause you big trouble if this is what I'm reading? Like Moose said, good luck with that. You may start burning your ignition system and bulbs out running 24 volts. I wouldn't even think of doing it this way.

If you add a second battery and don't run lights all of the time? As you ride during the day you will build up a charge in both batteries. So both batteries will be building up when any accessories are not used. Either way, you definitely need to wire any extra battery added to what you already have in parallel.

The only draw back to adding two batteries in a Parallel circuit is. Both batteries will be charged at the same time and the same amount of charge. The problem comes when both batteries are being drawn down so much, they draw down at the same rate because of the extra lighting. You may (depending on how many amps the extra lights are drawing?) run into a point where the batteries run low because the alternator can no longer keep up with charging the batteries. You may loose the ability of the alternator to keep the ATV running. And this can shut you down in the middle of the woods (until you turn these extra lights off and allow the alternator to create enough amps to run the engine again).

If you do a ton of running at night, and feel the need to add a few extra lights? You are going to need a larger alternator (charging system) on your ATV. Extra lighting and a big amp draw will eventually (more sooner than later) load up the charging system on your ATV to the point it (the stator) will get so hot the alternator (stator) burns up.

Also remember. If you do add a heavier alternator? Remember to run heavy wires from battery to battery.

Hopefully I didn't read your question wrong? If so, it wouldn't be the first time. Sorry if I'm on the wrong page with things????

HEre's the tricky part.... 2 batteries hooked in series = 24v... However think about a F250 or tractor trailer they require 24v to start not to run diesel don't require electronics to run.... anyway all your accesories are connected to a 12 v source not 24v so your lighting will remain 12v but if you must they do make 24v lighting and switches. which is more efficient take a 110v motor if you pop the cover off where the wiring is alot of the times there is a 240v wiring diagram also. Why??? 240v (aka220) is far more efficiant than 110v ok Im done.

No I'm not as far as power draw try using a 12v relay inline between the lights and switches.

My idea is Install two battery's in parallel then install this you just have to plug it in the night before and then your charging system shouldn't get to over worked during the ride being the battery's were toped off the night before.Or use moose's idea............

There is enough conflicting information posted in this thread now that I strongely suggest having someone skilled in the art look at the electrical diagram for the machine in question before adding anything.

Lots of things work on paper.
