+1 on this question - for the SC64w HI. (Sorry for imposing on your post @fnsooner )Which is the best battery these days for the SC64c LE? I still have a few of those red Sanyo 10A cells that Zebralight sells. I know the 64 is picky about its battery and needs unprotected. So if I were to pick up a couple more cells dedicated to the 64, which would you all purchase?
