They do look good till you get above 2 amps.
Yes you can use a battery that trips at 2 amps no problem, if you don't want to use it with a Xm-l on medium or high, some Xm-l's will use 2 amp on medium.
They will trip on a good TR-1200 on high on start up but if you have it start in medium or low with the mode memory it's fine as long as you don't switch it to high.
You can use them on a TR-3T6 on low mode but they trip on medium and high.
You can get away with them on a BC40 some times.
They trip on some Xm-l P60 drop in's on high but you still can use them on low and some mid modes.
You can run them on high in xr-e lights like Q5 and R2 emmiters on high as mine draw around 1 amp.
This is my experience
You can use them no worries on low current draw lights. But why spend dood money on Panisonic cells that are capible of high discharge rates, when you could of brought 4 good trustfire flames for the same price they give you more run time combined and betters protection and can handle more then 2 amp discharges and in my opinion have more usible voltage.
The problem I've found was when trying to run these protected cells in lights that draw more then your recommended max is if you acidently hit medium or high mode the protection trips so you have to put them back on the charger to reset the protection, this is painful and even more painful when you out and about.
Now your tests are great but you have shown the protection is bad and not that was claimed, I fear alot of people brought these to draw more then 2 Amps myself included.
