SparkFun Battery Pack as a UPS

"...by permanently holding the power button down, you are disabling the internal IC that protects deep discharge of the battery inside the battery pack. Once you reapply charging power to the battery pack, your device will power up briefly whilst enough charge is accumulated in the battery to reactivate the internal IC, at which point it will sever power to your device and continue charging the battery. At this point, if you attempt to temporarily sever and reapply charging power to re-power your device, it will re-power your device briefly (2~ seconds) before cutting power again. You must leave the battery park charging for about 10 minutes before attempting to interrupt charging power to reactivate your device permanently..."

And also , where did You get that micro screen from that You're showing on Your breadboard , I really would like a screen that small .

Yeah it was me that mentioned it on the SF site. The screen is the XMEGA XProtoLab breadboard oscilloscope, damn handy piece of kit :)

Also I noticed that You got the 6Ah battery pack , = Kick Ass !!! It's good to see other electronics people out there making videos . Take Care , You've got a new subscriber .

Some body mentioned this "Turning Off" thing on the SF website and the thing is that You have to draw a certain amount of power from the battery pack other wise it will think that there's no device charging from it. So You need to litterally place a resistor across the + and - terminals to constantly draw a certain amount of power , I'd try

50ma @5V = 100Ohm resistor , or 100ma = 50 Ohms, or on up in current . Otherwise the battery pack thinks that the USB device is done charging = turns off.
