Review on 🎮 YCCTEAM Battery Pack for Xbox One Rechargeable - 2pcs 1200mAh Batteries for Xbox One/S/X/Elite Controller - Charger and Upgrade Integrated Rechargeable Battery by Ryan Calabro

I have two Xbox One controllers, one of which was brand new and arrived via UPS the day after these batteries arrived. The first/older is model 1537 (according to the number in the battery section) and the other/newer is model 1708. Neither battery in this kit will fit either controller. It *almost* did. but the depth of the battery was scarcely great enough to enter. The dimensions of the plastic piece that is molded around the batteries looked identical to the plastic shield that comes with the XBO controllers, so they match. but the actual size of the batteries didn't seem to allow them to fit. I came here to check out other reviews and saw a post from the manufacturer/seller that said how to do it along with a youtube link but it just didn't work. I go. It felt like it was trying to break one of the battery tabs in the controller when I pushed it much harder to move it down. It was very close but unfortunately no cigar! I unfortunately broke off one of the tabs trying to fit it into my old controller so I can't get it back because it doesn't work. It only cost $20 so it's not the end of the world but I absolutely cannot vouch for their performance.
