10/10 Awesome upgrade

This battery mod is essential plug and play. I built two GBA consoles recently and only added this mod to one of them and boy do I regret it. I will be order another one very soon.

Blown Away at the quality

I have been very impressed with this battery mod. I have tried others in the bast that just don’t last, seem to drain randomly, or stop working all together. This battery lasts and fits absolutely perfect, I can express how clean it looks! Don’t forget to add the heat sink!!!
