Bought the funny playing recargable lipo and battery cover thinking it would be the best fit and match for my funny playing shell. It wasn't. The hole lines up great with the USB port, but the rest of the fitment was ok. Locks into place pretty securely, but there are a little bit of uneven gaps around the cover. Not super noticeable. All that wouldve been acceptable if the color matched. It didn't, it was kind of a yellowish off white compared to the brite clean looking white of the case. Might try the retro6 one, modify the original one, or just get a clear one to show off the charging board and LED.

I did two GBA ips mods and only I added this battery mod to and it was a huge mistake. I will be buying a second one very soon. It is super convenient and the battery last forever it seems.
