ok.  I keep forgetting that you are pre-phase-0 ;)

the third pin is actually just a NTC resistor connected to ground.
Should have 10kOhms at 25 celsius.  It should work even without that
resistor connected, but just to make sure I recommend connecting the NTC
- after all it's a safeguard against battery overtemp.

I'll ask FIC to send you a couple of more batteries.  Also, they should
be able to send you the remaining 'kit', i.e. stylus, lanyard, etc.
