As most people know in terms of OTF lumens due to cell sag the NiMH chemistry is still KING. My SST-90 2D Mag and 3D Mag builds all perform much better when powered by NiMH cells vs. IMR 26650/IMR 26500.
The 2/3A NiMH cells are rated for 30A and are about the size of a single CR123 Primary, but a tad shorter. I can probably fit 3 of them in a 18650 tube for testing or will make it happen without the tailcap.
In my tests these little cells always produce more tailcap current then the IMR 18650 or even IMR 26500. They are so small and the voltage input is the same, yet they are awesome. I use them to break in SST type of emitters too. 4 of them can be used to overdrive SST-90 emitters to "burn it in" These are the cells I let another CPF member borow to burn in his 4Sevens S12 and from his thread he went from 3.5A to 7A after "burn in"

I've heard of 2/3 C before but not 2/3A. So these things would fit in a Solarforce L2p body tube right? And they are about 3 volts each? How do you charge them?
