Can the Goal Zero 44001 be used to charge two 12v batteries connected in series?

Thanks for your inquiry. The batteries would have to be connected in parallel, not series, in order to be charged.

Yes, but the answer is not as simple as connecting the batteries in parallel. Because each battery has slightly different capacity and internal resistance, over time, you will get uneven charges between them. The charge controller will stop charging once one of the batteries gets full, leaving the other not-fully changed. The result is reduced capacity, that is, you will not get twice the capacity of individual battery. The solution is to insert battery balancer between controller and batteries. See this wiki page. http://en.wikipedia.org/wiki/Battery_balancing

You would have to put 4 batteries in series and all would have to be in about the same condition--not an optimal method. you would be better off putting two 6 volt batteries in series on a 12V charger

This is really for charging 12v batteries. Not aboe to directly charge laptops, etc, becuse the output in 12V from the controller. We use this on our RV to charge 4 marine batteries with the 30AMP controller, and run inverters to run appliances. It would be overkill to use this with inverters just for basic recharging, but it CAN be done.

Yes. It will charge both NiMH and NiCD batteries, either one at a time or up to eight at a time. You can even mix NiMH and NiCD. Just don't mix them in the same slot.

Yes, the newest version of these charges support charging both 12v/16V LiPo batteries. Just make sure you have the mode selected (its the blue icons on the front of the charger)

Yes, they're ideal for that purpose. You'll need a solar charge controller to manage the charge voltage and current, just as for any 12V battery system. The best and most efficient charge controller is the "maximum power point" (MPPT) controller.

Yes of course, that is exactly what the 12v output is for. However, it is only 4 amps so it would take a while. Also, it has no smart limit or anything so it will be able to overcharge the battery bank.I would recommend using a standard 120v AC charger plugged into the normal AC outlet of the generator. It will charge faster and safer.That said, the answer is yes.

This is a 12V battery. If you put 4 of them in series you'd get 48 volts, but that's far from optimal.

All batteries of the same amps can be used in series with no problems!the 12v in series may actually come down to 24-28V, as these li batteries give a tad more voltage; so make sure you got a good charger!

I am using this unit to charge single 110 amp battery. I think this unit can only charge single battery. But if you want to charge multiple batteries you have to make sure total Amp does not exceed 130 amps. And you might have to buy additional cables. I Hope this info was helpful.

As far as I know this is designed for 12 VDC. You could just connect the + (red) and - (black) to 1 battery for the 12 VDC

This charger can accommodate two 12v battery's, 24v total. Sounds like all you need is a single 12v charger.

I use my charge controller with a 12 volt converter, but I think you can put as much power in as you want,and that it will charge a 24 volt battery bank.Since I have 12 volt converter, I had to put all my 12 volt batteries in parallel, so as not to go above 12 volts and exceed the converters volts

If you match the proper size batteries to your panels through the right size charge controller you will have no problem charging the batteries. The generally accepted ratio is 1 1/2 watts of panel per amp hour of battery for a productive charge. This unit is not a charge controller. This is a 12 volt power inverter that converts the 12 volt power in your battery to 120volt ac for common use. I have one of these. It works ok for the money but it doesn't produce very "clean" electricity.

Only if you remove the jumper wire that creates the series configuration. Otherwise you will be basically grounding out the charger as you will have the positive and negative of each output wired together.

I assume you are talking about two 12v agm batteries hooked in series, that are then connected in parallel to a 24v source. First, battery minder makes a charger for agm batteries vs normal car batteries. Second, to be safe, if there were a way to disconnect the two 12v batteries from each other, and from the 24vsource, you should be able to charge them individually (red clip to + terminal on battery and black clip to a ground point on the vehicle). Do not attempt to charge while connected to 24v source or while the two batteries are connected together.
