4x Duracell is like $4.4
If each controller takes 2 batteries, that means using your cosmos is $2.2/h
An cosmos is $699, and Index is $999 So if you are going to use that VR headset more then like a 100 hours. You should just get an Index. Which will save you money compared to this battery hungry chink shit.
