Microstream aaa question

Can you use a 10440 battery in the microstream aaa without damaging it

yes

but
that light has no thermal regulation, and no low voltage protection

do you know how to use LiIon safely, in a light that does not officially support LiIon?
do you have protected cells?

dont tailstand it on high
the light could get too hot to touch

are you feeling lucky?:slight_smile:
