Disclaimer : Work in progress , and I`m a novice when it comes to electric wiring.
So this a mod that makes a QI charging build for the GBA much neater and gives you the ability to use the USB-C charging without having to remove the cover. You can achieve this without 3d printing, I`ve linked a Youtube video below, explains the wiring better.
I am going to updating the Design and parts list soon
You will need a soldering iron and the items listed below:
-the 3d printed models
Charging board TP4056 LiPo 18650 battery Charger
Battery LIPO 103450 (1600mAH Ebay £14.99) or LIPO 103048 (1500mAH Ebay £6.65)
1N4001 Diode
A QI charger receiver adapter, ( If your not bothering with the 3D printing, make sure its a USB-C one / If you are using the 3d print dosent matter which receiver you use)
some wire 1.5mm maximum wide and not to thin that it cant handle constant electric current ( Im leaving this your discretion)
Solder and Flux is optional, but will make this easier.
Electrical tape or Capon tape
This video should explain the wiring for everything,(dont worry the placement on the charge board is exactly the same) and what each part will do. With this parts list it you dont have to cut anything on your shell, but you will require to remove the original battery holders/pegs (someone in comments please tell me what their called thanks :)

Instructions, wiring is for the most part the same except for QI receiver that your gonna have to take apart:
Wire in the the battery onto the charging board
Grab the diode and solder wire (positve/Red) on each end so that the total length of the wire is around 8cm - important remember which side of the wire has the has the grey line on the diode.
Wire in the output for the GBA leave some length about 8 cm on the both,
Place some tape 2.5 cm long horizontally on the bottom of charge board
Place the 3D printed parts on both sides like in the pictures taping them in place.
Fish the wires through Body 2 (faces the battery contact on the PC of the GBA)
cut one negative and a positive wire for QI charging board output about 1.5 cm and solder them in
cut one negative and a positive wire about 2.5cm long and solder them to the charge input of the QI receiver.
Solder the in the 1,5 cm long wire to respective charge inputs on the charge board.
Place a piece of tape on top charge board.
Fish the 2.5 cm long wire one QI receiver board through Body 1.
Tape the qi charging board to the 3d print ( yes its a complete sandwich)
Solder the coil to the 2.5 cm long cables.
Fold the Coil on the top.
Just check on a QI charger if everything still works.
Done the rest is like the video
Yes Im going to video for this ;) once Ive finalised the design.
Thanks for reading and I`d love any Responses
