Hi y'all. I've been playing with tanks on and off for 10 years. My godsons want tanks, so I'm building them tanks!

In an attempt to keep this easier for their dad i want to install remote battery charging ports. I know Taigen sells one, but I can't find it in stock stateside. Does anyone have a simple wiring diagram i could follow? No other electrical mods are happening so I want to try and keep it simple.

Thanks!
