With this device you can upgrade your GameBoy Advance, GameBoy Colour, GameBoy Pocket or Gameboy (DMG) to support a LiPo battery in the simplest form possible – the diode drop method (not needed for the DMG). The diode drops about 0.7V – 1V so the red LED should light up on a GBA when the battery is around 3V – 3.3V on a regular cart.

Not recommended for systems that use more than 200mA – e.g any high current consumption flash carts.

This is a DIY part, you will need to solder your LiPo battery leads to the board and wires from the board to your device.

If you compare this to the GBA Reg & Charge solution, you waste around 9mA-30mA depending on the battery voltage, check our measurements here.

Features

• Use any LiPo battery you like (recommended to use a LiPo with a battery protection)

• In-line Diode to allow it to work with the GBA/GBC/mGB (uses more current compared to GBA Reg & Charge solution).

• Non-diode version works on a DMG (uses around 20-30mA more than compared to regular AA’s so it will put extra load on the DC-DC converter).

• You can charge and play but it will continue to be powered from the LiPo battery

• Very small form factor – 17mm x 15mm x 4mm
