A great add on to keep your Gameboy Zero powered for those long play sessions and aesthetically pleasing too with the custom battery wrap designed by my friend YaYa Designs.
All you need to do is trim the battery compartment of the ribs and battery terminal holders and this will fit perfectly in the compartment.
I have tested this with a Raspberry Pi 3 B+ (power hungry) and a Keidi HDMI LCD with the Retro PSU and it powered the system while playing a game for 3 hours and 3 minutes!
Get yourself a Retro PSU with this battery to make it the perfect combo to power your Gameboy Zero or other handheld projects!
4500mAh Capacity (closer to 4700mAh from my testing with battery capacity tester)
JST 2.0 connector, the standard in most portable batteries
Built in Over Charge and Over Discharge protection board
Custom Battery Wrap at no extra cost
