18650 Protected or Unprotected?

  • mdk0815 Friday, March 17, 2017 5:28 AM Reply


    Hi,

    Do you recommend protected or unprotected 18650 cells?

    Does this flashlight have an automatic switchoff when 18650 voltage is down to avoid total discharge? Or is it necessary to use protected cells?

    From one review. > When the batteries are running low the torch is starting flashing.


    That review is a year and a half old so it's possible new stock might not be exactly the same. 


    It's always safer to use protected cells with multi-cell lights, but it's also possible they might be too long. 


    Maybe @Maye_Tao could find out if it has changed, and whether protected batteries will fit in it?

    ALWAYS ask questions about a specific item on its
    page. Scroll down and click on "Post a new topic".

    Yes, in the sense that using protected cells will probably stop the torch turning into a bomb when one cell goes flat before the other. Not creating a bomb is definitely safer.


    The two cells in the picture ("battery not included") should not be taken as an example of what cells to use. One appears to be protected, the other not.

    "...One appears to be protected, the other not."


    Not to mention, one is a 3200mAh and the other 2400mAh. Definitely not good examples!
