I am not completely sure of what I’m saying, but to get the full power out of the M3, unprotected cells are required. That cell from Olight is protected.
Here you can read that it doesn’t work well on the Olight S1R Baton (900lumens) due to protection kicking in. [Review] Olight M1T Raider (500 Lumen, Tactical EDC CR123A) - #12 by rookiedaddy
The M3-Pro has, supposedly, more lumens, so I’m afraid that won’t give you enough power to feed that light on max!
