Khay pin tay cầm PS3 (PS3 Controller Battery Tray)

A1 and up PS3 controller batteries have built in standoffs but the knockoffs you can buy currently seem to have unreliable random size cells inside. I chose to get some 453048 Lipo's instead so I had a better chance at a reliable cell and they are cheaper at the moment. 

The maximum combined thickness that will fit is 6 maybe 6.3mm. The stock cell in a shell is 5.3mm. Max cell size it 58x36x5 since this tray is 1mm thick. Yes you could shorten the legs for a thicker cell but you really should leave space incase the cell swells and use a hard plastic for the tray to prevent it from being punctured when it does eventually swell. According to some guy on YT who's name I forgot charge current is 360ma so make sure cells can handle it. 

I just tape the cell to the tray and you should be able to use them on older controllers with the stand alone standoffs.
