YCCSKY Rechargeable Battery Pack for Xbox One, 2 Pack 1200mAh Controller Battery Pack Play and Charge Kit for Xbox One Elite Controller with 3FT Micro USB Charging Cable and LED Indicator

You get 2 with a double wire to charge both at the same time, only problem i had with it was the little piece on the bottom that goes into the controller, i had to break it off to get it to fit but now it fits like a glove, they work great and last for hours.

2/11/22 update - seller sent out a replacement free of charge. Replacement works great. Thank you so much and appreciate the fantastic customer service. It does not fit on an Xbox one controller. I bought these back in the summer but just finally had a chance to use them. Charged them up and when ready to put them on the controller, they dont fit. They look to be for a completely different controller. Now Im stuck with rechargeable batteries that I cant even use. Dont spend your money if youre looking for something to work with Xbox one wireless controller, because this doesnt.

Two battery packs for two controllers. Note that the battery pack itself has a USB port, you dont plug into the controller directly to charge. This is weird, but doesnt really affect anything. Havent had enough time to test the battery life/longevity, but even if its poor you just plug it in. I got some magnetic breakaway cables for even more ease of use.

The rechargeable battery packs are great. No big charging station. Charges within a couple hours. The indicator lights are nice to let you know when it is fully charged. They fit in the controller nicely matching the contour. I wish the charge would last a little longer. However you can play while charging.

Good charge time Hard to insert into cantroller Hard to insert charging cable

Battery life doesn’t last too long but for the price it’s not bad. You can also charge while playing. Not sure on longevity yet but with two you can always have one on the charger for back up

They last about 6 hours with a headset wired into the controller. No doubt they will last much longer if you have a wireless headset also they can be a bit difficult to put into the controller and take out.

Easy swap.

If you play with a headset the battery life is significantly less, but that is why you have two I suppose.

Battery life isn’t as long as I would like. But because it’s two pack that’s not a big issue.
