Ok so first time trying to solder the batteries onto the board without a battery holder
I had this simple 5v charging port to power the Wii

But then I decided to try and use the batteries since I got my red charging board but I'm having trouble since I soldered the batteries but I'm not getting any power to the Wii now

You have to connect a charging current to the red board once the cells are connected to disable the internal safety. Any time you disconnect the cells you'll have to connect a charging current again.

Small charging port that everyone uses? If it's a standard 3.5mm DC charging jack, the big pin closest to the connector is generally ground. Use a multimeter to verify the pinout just to be sure, though.
