Can this unit be connected directly to a bank of 2 12 volt batteries to charge them ? in place of a regular battery charger

Yes, but it is designed to charge deep cycle batteries. I'm not sure on connecting it to other types (such as automotive batteries). As soon as the battery is charged (reaches a certain voltage) it will automatically go into a trickle charge mode where it provides minimal power to maintain the charge. This mode is designed to prevent overcharging. As an aside, I'm not sure why you'd want to buy this to charge batteries instead of buying a regular battery charger. This unit would be overkill for such applications, since it is designed to provide DC power for the cabin of an RV/Travel Trailer while simultaneously charging the house/cabin batteries.

Only if your bank of batteries is wired 48volts. It WILL NOT charge at any other voltage than 48volts.

This item can be connected directly to a 12 volt battery. You would need to provide a charging source for the battery.

If the two batteries in series will make 24 volts DC, no. The charger on this unit is a smart charger and will likely fail to properly charge your batteries. In all probability, it will charge non-stop until the batteries and/or the charger burn out. I suggest either a 24-volt charger/inverter with a voltage reduction to match your 12-volt gear or a stand alone 24-volt charger and disable the charger that is built into the inverter.Hope this helped.AU

I don't think that will work. I charge the batteries with a standard outlet. Hope that helps.

Absolutely, if you wire up the appropriate 12V battery with the current capacity you need for the target runtime. It would be a relatively trivial hack to do if you want to, but is it designed to do so? No.

You won't want to connect the panel directly to a battery, as it could damage or overcharge it. The panel itself only provides a voltage, you need a charge controller between the panel and the battery. The one I used (http://www.amazon.com/gp/product/B001HWQZNQ/ref=wms_ohs_product?ie=UTF8&psc;=1) is not currently available, but should give you an idea of what to look for. You want a controller that can handle at least 30 watts and 17.5 volts input for charging 12v batteries.

Absolutely Not! Only the supplied battery pack 7.2 volts and its charger with a current of 140 mA supplied by a Yaesu AC adapter supplying 12 volts. Do not transmit using a discharged battery and relying only on the current of charger as the only source of power. Roger? Over and out.

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

Yes. Mine charges both batteries at same time. It's a 2 bank charger - 10 AMPS per bank. I have a seperate 1 bank charger for my cranking battery. It has seperate wires for each bank to hook up to your two batteries for your 24volt system.

Yes, just connect it independently to the batteries(not through the solar charge controller).

Yes,if you hook up two 6 volt batteries in series you will double the voltage to 12 volts and keep the amperage the same. + to - and -to +. Connecting the same batteries in parallel + to + and - to - gives you 6 volts but doubles the amperage. So if you connect them in series the 12 volts will be charged with any 12 volt charger. Sorry for the lengthy explanation but I wanted it to be clear. Good luck.

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.

The answer is Yes and No. Any 12 volt charger will charge it, but must have the right size "Spade Lug" connectors to mate with the battery terminals. Or have an "adaptor cable" to convert the typical 12 volt charger cable connector to the battery lugs. Be careful to use a low current charger adaptor, not a car battery charger.

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

Yep, you should be able to hook them up to two 12 volt batteries permanently as the wires are set that way. I didn't have room to mount the charger in the boat so I bought some battery clamps for the end of the wires that hook to the batteries and charge them that way. When the batteries are fully charged, I pull the clamps, unplug the charger, and store the charger away. I like this better as I can see when the batteries are fully charged and not have the charger continuing to trickle charge the battery. Although, they say that is ok. So far, this charge works great!!

In theory you can, but its not recommended and the NEC wouldn't approve. If you want to connect a 12 V battery to an inverter (to make it act as a power source) then look for an off-grid power inverter instead. They can come in 12V, 24V, 48V configurations.
