/**
* Per @spattinson
* MIN_BAT_MILLIVOLTS seems high. Typical 18650 are different chemistry to LiPo, even for LiPos that chart seems a bit off, other
* charts put 3690mV at about 30% for a lipo, for 18650 i think 10% remaining iis in the region of 3.2-3.3V. Reference 1st graph
* in [this test report](https://lygte-info.dk/review/batteries2012/Samsung%20INR18650-30Q%203000mAh%20%28Pink%29%20UK.html)
* looking at the red line - discharge at 0.2A - he gets a capacity of 2900mah, 90% of 2900 = 2610, that point in the graph looks
* to be a shade above 3.2V
