Kosker PS5 Controller Battery Replacement Kit Compatible with PlayStation 5 Original Controller, 8880mWh High Capacity PS5 Controller Battery with Extra Repair Tools Kit for Extended Gaming, 4 Packs

Sold maybe 15 controllers using these Kosker brand batteries on Amazon. Best price I could find with reasonable shipping, the only thing to note is that on some controller revisions I’ve noticed the battery pack can be a bit bigger than OEM and cause touchpad fitment issues when the rear shell is installed, what I normally do is scrape off the foam backing from the battery housing and if needed I’ll also modify the rear shell foam tape (remove tape and cut a thin piece off across the width, place it back in original spot but stretch it horizontally so it sits flatter than it did originally) and that solves it no problem. I usually have those issues with reshells though, not with installing into OEM shells
