What difference would use two flashlight batteries instead of one?
I have a flashlight that came with a CR123 (16340) 3.7V (880 mAh) battery. It also comes with a part which extends along the flashlight, so I'm guessing, that using some extension I would have to use two batteries. If you are wondering what is … flashlight is a plot of force L2M. So what if I use two of these batteries from 3.7 V instead of just one. Is it dangerous? LEDs could kill with it? If not I bright light or the batteries only last longer?
Part more likely additional cosmetics. Some people prefer long flashlights, others prefer short. Of course, you probably can use as a battery storage extra. Even if there is wiring, the more likely you will use the second battery in parallel. This will only battery.
