I want to tap my trailer tail light wiring harness and charge my 12v trailer battery. Will this work to prevent overcharging?

The Stinger SGP38 is a high current relay. It does not prevent overcharging a battery. It is designed to prevent your car battery from draining when the engine is not running and your trailer is drawing power from its battery. Its normal function is to charge your trailer battery from the engine when it is running and separate the batteries electrically when it is not running. Your trailer light harness may not be an adequate gauge wire.

You need to run a wire from the battery to the Stinger relay with a 60 amp fuse in the line. Then run another wire from the other relay terminal to the trailer socket terminal for your charge line.

I brought a NOCO GC026 flex regulator that prevents overcharging. Fits right between the battery connector cable and the panel cable.

You can charge your battery. You will need to get a charge controller to convert 24V to 12V. The controller will also prevent overcharging of the battery. Get a controller rated for 10 amps or more. I don't know how long it will take to charge one battery. This is a powerful panel, and would likely charge in one day or less.

you shouldent.. my trailer and most out there there is a green wire on each side that is your turn signal and the white wire that is your ground so that leaves your black as your battery/running lights.

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.

No, it depends on the trailer's 12V system supplying power. If the trailer is plugged into AC or if the battery has sufficient charge this will be available.

set up properly, this would work to charge any 12v battery. you may want to work in a solar charge controller if you are worried about overvoltage protection and other features that can add safety. one thing this will probably not do is bring a dead car battery back to life, if that is the nature of your question. BTW... I have successfully done this with this very panel, and a small 12v 7ah battery. A few good hours of sun will give you a good recharge trickle, but its not much power (smaller panel). You may want to consider a deep cycle battery if you intend to use the battery over and over after recharges. Hope this helps. set up properly, this would work to charge any 12v battery. you may want to work in a solar charge controller if you are worried about overvoltage protection and other features that can add safety. one thing this will probably not do is bring a dead car battery back to life, if that is the nature of your question.

I looked in the manual for anything to answer this and found nothing. As a mechanic though, I'd say as long as your using the lighter end supplied, I don't see a problem with that.... the lighter end does have a fuse, (3Amp fast blow) so IF something went wrong the fuse would/should protect both the charger and likewise, whatever it is plugged into. I've never done so with this, but routinely use a female lighter plug end with gator clips on opposite end to use battery power for all types of devices. On the other hand, if your asking will this CHARGE that battery.... I would have to say no. It's not designed to take a battery and charge (backwards) through the lighter plug.

No. Maybe. There are not instructions included for that function in the manual. I don't know why it wouldn't work though. If you start the rv with it plugged in, the alternator and solar charger will fry each other.

i am not a mechanic, nor electrical engineer, however, I doubt that the current required to charge this unit will do any harm to the battery. For a more qualified answer, you might check with your mechanic or dealer that sells auto batteries.

You need to run thru a charge controller of some sort in either case to prevent overcharging.

This would work fine for that application since all its doing is sensing voltage and closing or opening the parallel charging when applicable. You may also just want a three post continuous duty solenoid that will open only when current is being sent to the trailes lighting system (since it's a small 12v sorce to power the open and close.... ie trailers lights on would open the current flow. Trailer lights of would stop the flow.

It protects the electronics of the vehicle so it doesn't have to draw more current than the wiring might be capable of of. Many newer vehicles are using thinner gauge wiring that might not be able to handle the current draw for both the vehicle and the trailer lights.

You should have at least a basic charge controller to avoid over-charging your battery and possibly damaging it. The panel has built-in diodes to prevent discharging your battery when there's no light on the panel.

Yes. I would recommend you use a smart charger, like a Battery-Tender, that senses when the battery is getting charged and switches to a trickle charge, to avoid overcharging.

Never tried what you ask but the odds are high that it will. Trickle chargers supply a certain voltage and current level and rely upon time for the battery to accumulate the AH storage. They watch the battery voltage as it charges to decide when to stop. Since the voltage rating of the battery is the same the charger ought to stop when the battery is "full". It will just take longer to get there.

Yes it will, but if your camper has a wire to charge battery then you will need to hook that up with wire directly from battery
