Yes they are. That is what I am using in my MD3 with a M91BW (Keeppower 2300 mah 18500's). They do well. I have been using a KP 2000mah 18500 in the MD 1.5.
I did a test with them in my md3/m91b and they ran for 1 hour and 20 minutes, full output the whole time of course. Very nice performance.
Do the 2300 mah ones give you any issues with length in the md 1.5?
