Is it possible to use two or more 12 volt batteries ?

Yes, you can hook this up to two or more batteries. Just make sure to hook them up in parallel. + to+, - to-. This is a great starter kit, you can start with just this panel and one battery, then add more as you go. (If you are like me you will want more!) It would take about a day and a half to charge two car batteries when fully drained. My 122 amp hour marine battery will charge in a day. If you want a backup power setup more batteries per panel is better, but if you plan on a high daily usage you will want more panels per battery so it can recharge the batteries during the day.

Yes you can wire as many batteries as you want theoretically. You need to hVe adequate panels to charge your battery though.
1296117
You bet. Just put all you want in parall you want. Just Don't put them in serries.

Yes. You will need one a least. Six or eight is not out of the question either because, this will give you more electricity into the evening hours.

Yes. Wiring the wil depend on what voltage you will need, 12 or 24 volts by wiring in Series or parallel

Yes. I am using two 12 volt deep cycle batteries and have dry camped for 2 weeks with little generator use and works great

Yes, you can connect directly to a 12 volt battery. No charge controller is needed.

I don't think so. I tried to charge 2 12 volt batteries together for your same reason but that didn't work.

Sorry, but no it cannot unless your 24 volt battery is actually 2 / 12 volt batteries wired in series.

you can only charge 2 12volt batterys. cant charge them wired in series that gives 24 volts. cant charge 3 batteries.

I have an additional thought to your answer Kurt. While it may be true that the unit auto switches from 12 to 24 volts for two batteries. If more than two batteries are involved (in 24volt configuration) Additional batteries would have to be by two and in parallell. If you start with one battery (12 volts), just keep adding in parallel. Personally I would just assume hook up one battery at a time ...charge it up fast...then hook up the next one.

You can use it for two batteries but I am not sure that it is heavy enough to handle the current of the RV batteries. Check camping world and see the amperage rating of what they sell.

No problem at all. Just connect 2 or more 12v batteries in parallel. I use 4 x 12v batteries.

I don't see why not...12 volts is 12 volts, but I have never tried it. Best to double check.

No, They are 2 12 volt batteries that will make 24 if you wire them properly.

Yes you can. I do it all of the time. Note that both batteries will top out at 80% and not 100% when using this method.
1567123
Yes. You can use the 12 or the 20 volt battery. The 20 volt works best and will last longer.

Yes, you can connect ten batteries in parallel.It's important that all the batteries be of the same type and condition if possible. This improves both the safety and performance of the battery bank.

I don't see why not, I have mine hooked up to my batteries so basically I'm using it like a multi-meter.as long as you're not going over the voltage rated for the meter.use caution as most 12v panels exceed 20v open curcuit.

A 12V battery is too powerful. You need around 3V, or you could add a resistor in series with the 12V one.

Yes if you wire them correctly u can do that. There are different ways to connect the batteries. But are you using 24v. Most low voltage is 12v. Im no expert or electrician. Just based on experience

Yes, I use two in parallel with a twelve volt hundred watt solar panel for power in my camper. I really like them and will be ordering more.
