Differences between Pilas and other protected cells?

[greenLED]

on the subject of magnets and li-ions... there was somebody in NewBie's li-ion sticky thread warning about the possibility of the magnet moving ever so slightly and causing a short... I'm sure we don't want to go there and I just wanted to re-iterate that.

Also, your mention of the cell shoulder of Pilas pushing up the ground spring on SF lights is crucial. I offered that as an explanation to a fellow doing the extreme: three 168S cells in an SF M4 plus 2 A19 123 cell extenders (to make a 6x CR123 long body!!!) -- the modest cell length difference adds up -- in the attempt to make a Pila M4.

As the aforementioned fellow, I'll let you know if the spring works with my M4 using this 3x168s with 2xA19 extender tubes.....Jon is sending me one.
