Step 5Remove battery cable connectors
Remove the circuit board (carefully) and desolder the black (ground/negative) and red (power) cables from the battery casing (as shown in first image). Now you just need to connect the power and ground from your charger cable to the power and ground cables of your transmitter.
NOTE: You may need to extend your power cables like I did by soldering on a bit of longer wire to the battery connector cables.
You really should test your power circuit (again?) before connecting it to your transmitter circuit board so you don't fry it. You should be getting a constant 3 volts out of your circuit.
