I used a blue LED voltage gauge. ICR cells are junk, they are 1C, and very dangerous to over discharge. I only use IMR or INR cells, now, they handle 30C without even getting very warm, and aren't nearly as fussy about being drained too far. They cost a little bit more, and don't have quite as much capacity, but they are much safer and stronger than cobalt based cells. They are usually used in vaporizer "mods", which short the cell out directly through a half of an ohm of resistance wire. If they can do that, they are pretty tough. I run my 6 watt laser pointer off of 2, AAA size IMR10440 cells in series, and that beast draws 10 or 12 amps. It only runs it for about 2 minutes, but that is impressive as hell. Plenty of time to burn some stuff, and get my laser freak on.
