Exclamation-triangle-fill.svgLithium batteries used in the battery packs below should be used with caution. Batteries should never be punctured or cut, and if a scenario arises where something like that occurs then they should immediately stop being used and disposed of properly.


Game Boy Advance

The Game Boy Advance has lithium battery pack mods that can be dropped into the battery compartment without any soldering, allowing you to power the Game Boy without relying on AA batteries. For OEM/stock shells, the battery compartment will need to be modified to trim off the plastic separator sitting in the middle. Pre-modded IPS shells usually already have this trimmed but not all of them do. A cut-out for the USB port will also need to be made on the battery cover, unless one is purchased pre-cut.

Note that the battery run-time using a battery pack mod will likely be lower than that of rechargeable nickel-metal hydride batteries (Ni-MH).

Exclamation-triangle-fill.svgNot all of these mods support play and charge meaning you cannot have the Game Boy Advance powered on while it is also charging the battery. These mods utilize the TP4056 charging module which does not support load sharing (though it can be added). The TP4056 can get very hot during charging as well, and it is sitting on top of the battery. Be responsible to take note of any temperature concerns during charging and to not play and charge if the board doesn't support it.
