how many 12v batteries would i need for the bank?

I bought two panels, have not installed them yet. Starting out with 4 batteries @ 100 amps, plan on going to 8 and adding two more panels

Go with two high current 12 volt deep cycle batteries. Wire them in paralell; not series. You only want 12 volts; not 24. Use the same brand/capacity and type. Don't mix brands or current ratings. THE HIGHER THE CURRENT RATING;THE MORE TIME YOU'LL GET ON THE BATTERIES. I've seen systems with more than two batteries however, you'll need additional equipment to pull it off safely. You could also use a marine A/B Battery transfer switch and draw from bat A bat B BOTH of OFF. Don't forget to use fuses at key points. Amazon also has some pretty good books on the subject.

One will work. I use 2 125 amp marine batteries from WalMart and it has worked well.

Totally dependent on how much reserve your seeking. As always...you'll need a charge controller with the batteries to prevent damage to them from overcharging and an inverter depending on your actual power need. Amazon has a few good books on Solar, you may want to pick one up. I have 5 of these in series and no batteries, at the moment leveraged only for operating my solar well pump.

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.

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

Yes you can use a converter 12 v.I have a bank of batteries and a converter 12 v., 1200 wat and works perfectly. Consumes about 300 wat

That will depend on how many you are using and how they are configured. Assuming you are using 1 (or any number in parallel to obtain more amperage) any 12 volt trickle charger would be sufficient. I use both a solar and an electric trickle charger myself. Another thing to consider is how often you expect to use and/or drain them. If you are using them for emergency back up, you will needs a slower charger than if you are planning to use them constantly. If these are going in a vehicle, any 2-10 amp charger will do.

A 12volt car battery will work. But most people including me, use a deep cycle marine battery. It lasts longer per charge.

If you are out west, 400 AH @12 volts would be a good match. On the East coast, or in some place cloudy like the Pacific Northwest, you might want 600AH @ 12V. Since you want to use 6 Volt batteries, Trojan T-105 would be a good choice. Either 4 of these or six of these hooked up in pairs with a MPPT controller. However if you are asking this question, you might not be smart enough to wire these properly. Get an expert to help.

I use a 9v battery. You will need to adjust the battery connectors a little, as it tends to be a little wide.

You are going to need sufficient cord length and appropriate connectors for each application. If you are wanting to charge two separate items simultaneously, obviously you will require two separate cables with the appropriate connectors. File that under Common Sense 101. ;-) How many accessory cords and connectors did you receive with the 2 bank Battery Tender? If you received two, you may not need any. If you only received one set and wish to charge two items at the same time, you are going to need another set!

Yes, any 12 volt car battery will work. I prefer using a deep cycle battery.

I powered it up on my bench with a bench supply. There is no reason that a 12 volt battery pack would not work. Pay attn to + and -. Not sure how long it would last. You would have to look a the current draw of the desplay.

It's pretty straight forward just keep in mind that you should use at least 10 gauge wires to connect unit to 12v battery,if you use wire less than that you could have a problem as with any of these units.

Just pick up 12 volts. Batteries are in series so just configure enough to get 12 volts and you're good to go.

I can't imagine why you would not be able to. I'm doing three. You can connect one bank to the most important (starter for example) battery and the other 5 parallel on the other bank. Or you can split it up evenly. Many options but it seems real quick for me.

There's a power in (-,+) which is visible in the picture on the lower right hand side (It's the little blue tower with only two things on it). I used 4 AA batteries. You should be able to use more then that but it's up to you I don't know the recommended voltages for this off hand.

I know you need 1 9volt and the rest are AA Batteries but I'm not sure how many of the AA you need!

I would say no. You'd need a battery bank of about 6 12 volt re batteries ... and at such a drain from the freezer I am thinking it would take about 120 watts per hour of solar panels to keep the bank charged overnight. You'd want a much stronger inverter and controller than what comes with this kit.
