Helder’s 4500Mah Gameboy Zero Megabat Battery, A great add on to keep your Gameboy Zero powered  for those long play sessions complete with the custom battery wrap designed by YaYa Designs. All thats needed for install is to trim the battery compartment of the ribs and battery terminal holders and this will fit perfectly in the compartment.

This battery has been tested with a Raspberry Pi 3 B+ (power hungry) and a Keidi HDMI LCD with Helders Retro PSU and it powered the system while playing a game for 3 hours and 3 minutes!


  • 4500mAh (closer to 4700mAh from my testing with battery capacity tester)
  • JST 2.0 connector, the standard in most portable batteries
  • Built in Over Discharge and Over Discharge protection board


You will need to swap the polarity round on the connector to use on one of Kites Circuit Swords or on the Adafruit Power Boost 1000c. Its super simple, click here to view the guide.
