  (need to add info on identifying the type of driver and choosing a set 
  of calibration values)

  <ToyKeeper> On the Ferrero Rocher, I see one labelled 41. On the 
  Moonlight Special, it's labelled E2. The ADC readings between the two 
  differ by about 10, which is enough to make LVP and battery charge 
  estimations not work well.

  <wight> Mystery solved - that's PMEG1020EA. The lower forward voltage 
  should improve the driver's overall drop-out by a small amount.
