The A123 26650 M1-B cells will throw over 200 amps to a short circuit.
Considerably more if they are at optimum temperature. :-)
The short circuit current will actually go up as the cell heats up. This
assumes that whatever caused the short hasn't vaporized....
These are _very_ well designed cells. They will last over 10,000 cycles
BTW. 100% discharge and charge at 1C rate, 20 Celsius, and retain more
than 50% of the original capacity. No Joke.

Lawrence, when I removed some of the cells from that pack that you picked
up, I cut the straps with heavy duty scissors.
One time I accidentally shorted the cell I was removing while cutting and
the current was large enough to bite a chunk out of the scissor blades...
These are *very* low resistance cells, so the short circuit current
consequently is very high, even at the low 3.5V of a single cell.

https://youtu.be/zEXx_2Caefc?si=j66-Advfy42A7-Aq I wasn't too careful
separating some cells. Nicked a few. Used in flashlights they are awesome.
However, I nicked a few near the base and my hacked flashlight spring
shorted the cell. Smoke and brown fluid. Oops. I will tape nicks and avoid
making them in the future. Also use an adapter of pvc for extra safety.
