Charging a 3.7v Lipo

Well, I bought one for a laugh.

Spec on the Ebay page (wonders will never cease)....

3.7v. 30mAh (yes - I have dropped the capacity even further - the load is negligible for such a short length of time).
Charge recommendation: Constant current charge 0.5C to 4.25v, then Constant voltage 4.2v til charge current is less or equal to 0.05C.

Built-in cut off voltage 2.75v.
Charge time 2-4hrs standard. 2 hrs Fast.
Protection: Over charge, over discharge, over current, short circuit, over temp.

Just got to work out what programming resistor I need for my Lipo charge IC.
Still have not quite got my head around that yet.
