I am not sure about the reason but one controller out of three controllers i have does not work with these battery packs

I tried this battery pack with my nephews controller as well and it didnt work with that either

They work great but dont seem to hold the charge they claim maybe a typo

This product works as expected im impressed with that the only thing i did not like was the charging unit it did not come with the plug adaptor just the usb port and it sticks right in the battery it does fit into my old unit which seems to work well

Battery life seems a bit short for what was advertised bit comes with charger and was cheap so itll do the job

Not so good when there are 2 kids both wanting to charge their controllers
