If you use protected, non IMR 14500 cells:
- the cell won't be able to give as many Amps as required to activate the turbo mode.
- the PCB will block the cell when try to access to turbo mode (because of too many amps), and the light will turn off.
The switch cover is made of rubber.
Thanks a lot for the reply! I am curious what's the LM if one uses a regular AA, alkaline for example. Manker didn't say, nor can I find this in any reviews. Thanks!
the same question goes to T01 also.
