PS3 wired battery pack?

[ToxicMoofin]

Prolly the wrong forum but, currently Im using a PS3 PDP after glow controller that needs batteries. I bought rechargable batteries thinking that would solve the problem.

While it has taken created another being I need to wait 7hrs for the batteries to be charged. What I was wondering is if there is suck thing as a wired battery pack? I know buying another set of rechargable batteries isn't a bad idea. But still, for future references lol

But yeah best bet buy more batteries and continuously cycle with batteries you charged over night or buy a cabled ps3 controller.
