Charge wire question
Hello everybody, I have a 12' enclosed cargo trailer and I wanted some better lighting in the inside. So I mounted two LED lights in the inside and a battery on the hitch like a camper would have. Here's my question, I'd like it to charge while I'm driving so I added a 10ga wire from the positive post straight to the trailer wiring plug. Is this correct? Wouldn't the 10ga wire get hot or melt if the trailer battery was dead needing lots of amps? Doesn't really seem like there is enough room in the plug for a larger wire. Thanks for the help.

most use a 20 amp fuse at tow vehicle...
and 10 gauge will handle 20 amps easy..
a dead battery should be changed by a 120 volt battery charger.. NOT a 12 volt car/truck.. good way to kill an alternator.
once a 12 volt battery is drained below 10 volts.. some of its life is GONE. and will never recover fully.

Yes for sure, 30amp should be a good match for a 10ga wire hey?

That's fine. The charge lead is also already fused under the hood of your truck. There's really no way you can deliver more amperage to your trailer than that fuse will pass.
