if, as materials with the unit says, "nominal input voltage MUST MATCH the voltage of battery or batteries" can I connect more than one 12 v battery? diagram shows either a single 12V battery or two 6V batteries as examples. I want to use two or...

You can connect as many 12v batteries as you like. You just need to make sure to connect them in parallel, if you connect them in series you will have some serious problems.

Battery Tender site indicates multiple batteries can be connected in parallel. They need to be the same type and voltage but do not need to be the same capacity. If the connectors fit or can be made to fit, I think this would work as long as total capacity is within limits stated on Battery Tenders web site. For storing batteries over the winter, I would probably charge all batteries separately and then connect them in parallel using this or direct connects. I plan on taking a closer look at purchasing the item :-).

Two 6V wired in series is 12V not 6V, and yes it will. "Per Customer Service Baccus Global, LLC the unit will operate at 12V with two 6V batteries with the same capacity."

Yes, two of them. Make sure they're alkaline as it likes higher voltage (NiMH has a tendency to not work well)

You really don't want to do that. I have a special 6 or12 volt charger for that purpose; it's a Smart Shot charger, by Yuasa. Accumate also makes an excellent 6/12 charger. I have both. Bear in mind that if you set up your 2 (6) volt batteries in a series configuration; you're dealing with 2 separate batteries with individual and unique needs. It is definitely not advised at all! With respect, buy yourself a separate charger and use the Optimate 6 in a way it is specifically designed for; that's 12 volts in an individual battery. It is clearly my advice to "NOT" use it on individual batteries that are hooked up to total 12 volts. That way you'll have 100% conditions to obtain the best outcome. Hope this helps.

If it does not match the ones you received with the unit, I do not believe they are available. Using the adapter with the direct ring terminals, connect that and plug the unit in where the different adapters hook on. If it is a 36 volt system, it has been less than satisfactory for that voltage. It seems to work on new batteries but not older ones.

First, thanks to Kevin for telling us that the adapter is a 12volt adapter (from the label). I just want to add that my battery pack - as I suspected - outputs 9 volts; the six AA batteries are indeed in series. Therefore, I suspect anything from 9-12 volts should work. Also worth noting is that when my batteries died the other day, I just rotated them and am getting some more use out of them; I expect to have a power source fabricated by the time I need to replace the batteries.

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

Hello,If you are charging 12v nominal battery bank you can input up to 400 watts of solar power.If you are charging 24v nominal battery bank you can input up to 800 watts of solar power.The wiring configuration of the 800 watt panel setup must be done so that you do not parallel all of them or not series all of them or else the panels will either go out of the 100 VDC or the 40A rating.The 800 watt setup must be wiring in series/parallel.Please let us now if you have any further questions.Regards,AW

I assume they are 4 12volt batteries. Ideal would be that all batteries in series share the same load and charge current. If you are only using it for very low current stuff, I don't thing you would have a problem connecting it across one of the 4 in series.

It is my understanding this unit can work for both a 12 v and 24 v system. I think that you might be confusing the one with the other. On one side you have the system charging via the pv modules there is a max input voltage of 100 volts . And on the other end you have your voltage bank. This unit supports a 12v, 24v, and 32 volts bank. The choice is yours. If I can be of help email me at Edgib@bellsouth.net.

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

Yes, connect two 12-volt batteries in series to get 24-volts. Here is an article with an image of this: http://www.cabelas.com/product/Marine-Battery-Wiring/531785.uts

A battery is a battery and voltage is voltage. If the machine will run from 12V DC there is no reason you couldn't use it. I would have to imagine there are better solutions for that though.

the battery pack has multiple voltage levels, 3, 5, and 6 volt. if a series circuit is being powered this will be able to do both voltages. most parallel circuits will work also.

no just use 1 12 volt battery if you have a 48 volt system or 2 6 volts if you have a 36 volt sys.

ALWAYS use matching batteries. Same voltage/amperage. Don't mix old with new.The lesser batteries will drain the better batteries, causing premature failure.
