Turboexpress internal rechargeable battery mod

[turbokon]

Finally found the perfect rechargeable battery solution for the turbo express thanks to a fellow tech.  Battery is charged thru the express ac plug.  The only thing needs to be done is mount a tri color led somewhere on the outside so its visible. 





Here is the charger and booster circuit I'm using

You can also series two 1000mAh batteries together.

Note, it can only be charged with a 5v power supply.  I found that the sony psp adapter works but you have to replace the jack on the express.  Replacement jack can be found at console5. 

Also you have to rewire the express jack.

Gorgeous.

Looks good, especially since you didn't have to hack up the battery compartment or cover.  How many hours of OBEY does she give ya?

Testing battery run time now with my 3.5" LCD modded express.  Based on my estimate, it should last 4 to 5 hours with the 2500mAh cell.

Great job!.  Even at 4-5 hours it's a huge power saver.  Was there even an aftermarket/first party external battery pack ever made for the Turbo Express like the Game Gear, Game Boy, or Lynx?

[famiac]

The listing shows that the battery has a 10Wh specification. The turbo express/pce gt acts as a 4.6W load, so the battery should only be able to power it for ~2.2hours.

Turbokon, could you try running it on a full charge, preferably on a system using the stock screen, and telling us what happens?

I will have to redo the test.  It was at 2hr 45mins when the game froze and I'm getting a white screen now.  My region chip died. 

My calculation was based of a 3.5" lcd express which draws a ~510 mA load.

[NightWolve]

I remember Steve put the maximum draw at ~600mA which is why a 1 Amp 6VDC regulated power supply is perfect when you wanna upgrade and get rid of the original. Less heat for the internal 5V regulator and it'll all still work fine.
