Naturally you will most of the time not have turned music up to clipping level so power consumption will be much lower, typically under 100mA.

Your assumptions are correct, I measured today the current draw.
So I assume a 1800 mAh Lifepo is good for 8hrs play without discharging to the point of the TA202o cutting off?
