New guy here. Some units can use 1 18650, some take 2 123's. What would you expect the difference in performance to be.
Situation; one 18650 3.7v, 2600ma/
two 123's 3.0v, 1300ma each.
Which would run longer?
I assume the led module can handle both voltage inputs.
PLEASE SHED SOME LED LIGHT ON THIS!!!
