Can You Charge Your Trailer Battery Using a 7-Pin Plug? ๐๐
Yes, you can โ and hereโs how it works!
โ
The 7-pin plug on your tow vehicle has a 12V auxiliary pin that can maintain your trailer battery while driving.
โ
Use heavy-gauge wiring (10 AWG or better) for better charging efficiency.
โ
Add a fuse and battery isolation switch to protect your system.
โ
For smart alternators or longer hauls, consider a DC-DC charger for a steady charge.
This setup keeps your trailer powered on the goโno need for constant shore charging!
