3000mAh Battery in an iPod 4th Gen?! Here's how.

Want the massive battery capacity of an 3000mAh-modded 5th/6th/6.5th/7th gen iPod but in the retro form factor of the 4th gen? Well now you can. With a saw and a soldering iron, we dive into this custom build.

Warning: This mod is slightly more advanced than a straightforward battery swap. We'll be handling cutting tools and hot irons so it is not suitable for beginners to iPod modding. Please make sure you have the appropriate safety equipment such as gloves and goggles to protect yourself if you try this.

While I used a colour-screen model 4th gen in this video, this process is mostly identical with the monochrome version of the iPod and the only difference is one screw which I will point out in the video.

The iFlash board I used is the iFlash ATA1 which is specifically designed to work with the 4th gen. Do not attempt this mod on any other iFlash model (e.g. iFlash Dual, Quad) as their internal circuitry is different.

A HUGE thank you to everyone in the r/iPod Discord server for their time and kind feedback when reviewing early test footage while I was making this video, I really appreciate the help!
