With this device, you can upgrade your Gameboy Advance or Gameboy Colour to support a LiPo battery. Features over 90% efficiency, charge & play and supports the red power LED indicator on the GBA - it will light up when the battery is low.

If you use a Turnigy 2000mAh battery, the battery life is estimated to be 20-24 hours (to reach around 1650mAh used - 3V reading on LiPo) on a 32 pin backlit GBA running a regular Gameboy cartridge which draws 85mA at 2.9V (LiPo consumption at ~70mA). Cutting/filing some parts of the GBA battery compartment is required if you use the Turnigy battery.

This is a DIY part, you will need to solder your LiPo battery leads to the board and wires from the board to the GBA/GBC to power it and another connection to a capacitor on the GBA/GBC board. You can use double sided tape to stick the board to the battery so that it doesn’t move around. Check out the How to Install section for a GBA installation guide.

If you compare this to the usual diode drop method, you don’t waste around 9mA-30mA depending on the battery voltage, check our measurements here

Each unit is assembled and tested in-house. You will receive the product as pictured.

Features

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

• Uses a DC-DC to give the best efficiency, more than 90%

• Gameboy Advance power light turns red when the LiPo battery drops to ~3.33V. Gameboy Colour's red light becomes much dimmer.

• Charge and play at the same time; automatically switches GBA to be powered from the 5V charger when connected.

• Micro USB or USB-C connector option
