Yes, a hot wire from your vehicle's battery to a battery on your trailer will charge the battery on the trailer. I'd suggest using a minimum of 12 gauge wire and fuse it at about 20 amps where it connects to your tow vehicles battery or charging system. If you are running your trailer off your trailer battery you want to be sure to disconnect your tow vehicle from your trailer so you don't run down your vehicle's starting battery.
Another option is to add a relay that disconnects the trailer's battery from the tow vehicle when the ignition is switched off.
Hope this helps.
Cheers,
