I'm surprised Gummi isn't having problems with that high resistance UF batt. But we don't know what resistance/amps/watts he's at.

4.4 volts and ~3 ohm atty that should be ~ 1.5 amps and 6.75 watts (I think) but I haven't a clue what the battery is being asked to do.

The battery is 3.7 volts, the TI Booster chip kicks that up to 5 volts. but that is a bit to much for me, so I wanted to step it down to around 4 1/2 volts. The resistor tricks the booster chip to put out less than the 5 volts that it was designed to.
You can find info on this chip scattered all over this forum but not so much all in one place. do a forum search for TI Booster.
