lasts a long time and easier than carrying around AAs

Ethan Suhr
Works as Advertised!

Super easy to install, no soldering required!

Rechargable Battery is Clutch!!!

I installed a funny playing ISP screen and I generally keep the brightness from 1-10(15 is highest). I'm getting 5-6 hours battery life which is amazing. Easy to install and I can play while charging but will run hot so I don't recommend doing for a long period. Overall love the product!!!

Jordan Wagner
Works as expected

Great mod easy install had to trim a small amount of plastic. I wish there was a link to some instructions or something.

Benjamin A Diamond
Perfect for what I needed

It's such an immaculate fit; it looks like I installed the USB myself.

Battery slightly to big for shell

So the funnyplaying cover doesn't fully close on the funnyplaying battery in the funnyplaying shell...

Thank you for the feedback! We have noted ourselves that the fitment of the FunnyPlaying battery in their shell and with their battery cover is a tight fit, but it does fit from our experience. This had been noted on the product page. If you are still having fitment issues, please reach out to us at so we may try and resolve this for you.

When you receive a backlight/LCD kit, you should perform a dry run before installing to assure that nothing has been damaged in transit. A dry run or test fit means the kit is not installed in the shell. This includes, but is not limited to, the use of adhesives, brackets, and any performed soldering. All ribbon cables should have no bends or creases in them. If you are unsure how to perform a dry run, please contact our support team and we will be happy to help. Backlight kits that have been installed are not eligible for replacement or return. If a backlight/LCD is returned and shows any signs of having been installed, it will not be eligible for a refund.
