Rechargeable Battery Pack for Xbox Series X|S/One, 2 Pack 4440mWh 3.7V Battery Pack for X-Box One/S/X/Elite All Xbox Controllers Supports Use While Charging (Includes 2 Batteries Only)

They work very well with the xbox series x controller. They honestly surprised me. It’s super easy to to put in and take out. you can still put the back cover on and everything feels normal. You don’t have to recharge it every-time you play.

Holds a good charge, great value for 2 batteries. I charge it daily and it hasn't ever come close to dying on me for over a year.

One battery works great, while the other doesn't hold a charge. Still a good price for one battery.

Great product fits perfectly.

These were so utterly disappointing, and just garbage all around. They don’t hold a charge for very long, you can tell it’s constructed from extremely cheap materials. Don’t waste any money on these!!

Works great

It comes with two block of batteries and it did the job pretty well like 18 hrs straight after fully charged.

Great product
