3.7V 17670 1800mAh = 12 hours of BR life?

[Midknight]

If your running a PHR-803T blu ray diode at 150ma with a flex drive, using a 3.7V 17670 1800mAh battery. Would you get 12-hours of life off one charge?

The driver would absorb some current too, wouldn't it? I mean that's driver output, not driver input you've got listed there.

Correct. It wouldn't be 12-hours. But it would be a lot. I'm going to run a test as soon as all my parts get here.

The ma load on the batt would be higher than the ma going into the diode, this is mainly due to the voltage diff.

So it is
I*V=I*V
150max5.5 = x(ma) * 3.7 (4.2-3.x)

This does not include the minor inefficiency of driver. Not too good at electronics but it should be right
