Power System and Battery Charging

What happens here

Nate explains the trailer's power system, emphasizing that it runs entirely on electricity. It's equipped with a deep cycle AGM battery, which charges automatically via the truck's RV plug connection while driving. For charging at home, there's also a 110V wall outlet plug. He uses a built-in voltage gauge to demonstrate the battery level, showing it at 12.2V initially and then 12.5V after driving, indicating efficient recharging during transport.

Goal: Explain the electrical power and charging system of the trailer.
