battery to usb charging?

[chinhps3]

so my situation is, i have a ps3 remote control for movie viewing. that thing drains batteries so fast. yes i know it can last several hours but if your watching a movie the remote will be on and running away the battery. only after about 3 movies the remote is dead. i do not want to have to buy new batteries and replace them every 3-4 movies.

so i thought just like the ps3 wireless controllers, i should power it via usb as well.

so my question is, are you able to convert the remote control from taking battiers and wire somehow a litium ion battery and rig it so it will be charged via usb?

if so, i know the process will be more extensive but any info on what to expect or how it should roughly be done would be appreciated.

thanks

In your ps3 remote control what type of battery has? What voltage? How many batteries? Why not use high capacity rechargeable batteries?
