  1. I noticed you made a mistake calculating the battery capacity. Your testing device showing 2.1 Ah at 5 volts which gives us 10,6 Wh. Divide 10,6 Wh with 3,7 volt (nominal voltage of a li-ion cell) and it gives us almost 2900 mAh. Of course, this also include some losses in the step-down conversion, but these are normally fairly small.
