I want to use these to keep my marine batteries charged. Do I need to use controllers with them or can I just connect directly to my battery?

I think the solar charger has a special diode, that only let electricity go in one direction once the battery is charged it stop

You'll need a controller, I'd buy the deltran brand instead as they are more stable and have the built in micro chip that won't overcharge and fry your batteries.

No it's built in no charger required have been using 2 of them for over 2 years no problems

Although I don't recall the instructions saying that you can do this, I suppose that you could. However, since they do not provide a wall charging adapter you'd be taking a risk of killing your battery and controller. I'm not sure why you would want to do this though. It's simple enough to just plug your controller into your One and disconnect when you want to play. Since the One will still charge in standby mode your controller will always be ready to use. I've had 0 problems with this product.

You will need cable to attach the charge controller to your batteries. The shorter the better. I used an inexpensive set of jumper cables with 8 gauge wire and I had to reduce it at the controller with a cable end that is a post, generally found at a car audio parts store. The battery end uses a standard ring connector that will fit your battery post.I kept that distance less than 10 feet.

You don't need a controller because this unit does not supply enough amps to overcharge a regular sized (car, boat, etc.) battery. If you test the voltage under no load it may scare you because it's too high, but if you apply ohm's law and understand that the current is limited by the capacity of the unit, you'll find that the voltage under load is only a couple of tenths of a volt higher than the battery in its disconnected state.

Yes, I keep them hooked up to 3 batteries that power my trolling motor on my boat. They do a wonderful job and while sloppier, have lasted much better than those "boat" battery charging units that coast enough to buy ten of these. I keep three of these hooked up all the time.

It does need a controller. Will it charge/maintain your deep cell; mine is hooked in series with another 100 watt panel and it seems to work fine with my 4 group 31 batteries. It takes about two days for full charge after I run them down (which has only happened twice in two years).

I have used this to keep a 12 volt marine battery fully charged all summer and it worked well. I used a charge controller between the solar panel and the battery. This is the one I used.AGPtek® 30A Solar Panel Power Battery Charge Controller / Regulator 12V / 24V 30 Amp with PWM Type of Charging (Automatic Lighting Control + Time Functions). Of course, you can use any charge controller.

I have found soldering them is the best way. I use them in marine apps with fail proof connections so far.........hope this helps:)

You might want to contact the seller Solar-X for a full answer to your question. Can only say I have had this solar panel attached with alligator clips to my 12V marine battery without the controller for a year and a half (boat is in marina in-water over winter January through March and not used for those 3 months) (live on the coast of S.C.). I have a power cut off switch and in April turned it on and the console gauge showed full charge and started the O/B upon ignition. Before purchasing this solar panel I bought a portable battery charger (just in case) and to this day have not had to use it. I credit the solar panel(sans the controller) for that. Hope this helps.

No need to disconnect battery. As you draw power from the battery, it will need to stay connected to the controller for proper recharging.

I am charging 4 deep cycle marine batteries with no problems using this charge controller. So with your use it should work fine.

You've probably checked on line, but this is a good site to referencehttp://www.chargingchargers.com/tutorials/solar.html25 milliamps is really small, and may not generate enough watts to bring the controller into play.I connected the controller to a largish solar panel, output approx 20 volts, for keeping my boat battery topped up.. the combination seems to work well at this level.Hope this helps.

This unit cannot be charged. It is charge/discharge controller and switch. You buy external battery of required capacity, and connect to this device. The deep cycle marine battery 100AH will run these for tens of hours.

Use a 12 volt largest marine battery you can get. Keep it charged up and should last all day while out

If you're conecting it to a 12volt marine battery directly- you will need 10-12 size connections. The ones that come with motor are very small that will not fit over connections - you'll have to cut off the small ones and replace w/10-12 size. Also, with foot control you might want to buy a mount for pedal. It tends to move. I have both and prefer hand control 45 for that reason. Hope this helps

the load is the battery(s) the controller is to keep the batteries from being over charged. So no you do not need to run the load through the controller

Yeah pretty much, and that's how I ran my Xbox 360 controllers, but I do recommend this, because changing out the batteries and charging them is annoying, this is a much better solution in my honest opinion.
