Please note that high quality 18650 batteries are required to access and maintain the turbo mode of this light. 2 CR123s will likely not power turbo mode and many the protection circuit of many protected 18650s will kick in when the light is switched to turbo. Two batteries that we have tested and confirmed to power the turbo mode are the Eagletac 3100 mAh 18650 and the AW 2900 mAh 18650.
