This PCC is supposed to fit M401 batteries yet the length dimension shown is the same as for the original PCC that was too short. How is this accomplished - is the internal charging battery connector repositioned/lowered or is it merely that the descriptions for the PCC was "cut and pasted" from the M402/3 PCC page?
I LOVE the original for the most part excepting that I had to drill a hole to fit my m401s and that it "seems" the charger requires that the vaporette battery be completely discharged(?) and balks at "topping off" the charge of batteries that are only partially discharged. Maybe needs a resistor change for a wider "window" on the comparator or change to the voltage detector code if a PIC is used for when the device initially connects to a battery to be charged.
