I did a little googling and noticed that some people burn out their flashlights by using RCR123A batteries instead of the intended CR123A batteries. The former are rechargeable. Well, I'll be! That explains how I've destroyed two flashlights! If I understand what I'm reading right, the CR123A provides 3.0 volts whereas the RCR123A provides 3.7v when charged.
More reading shows me that there are 3.0v versions of the RCR123A available. Are these any good? Do I sacrifice capacity by using these? I don't mind, if it's not much.
My idea is to use a general purpose, modern flashlight to use as a secondary light for my bike. I want it to be excellent, so I have my heart set on the Fenix PD30R5 PD30 R4 257 Lumen Cree XP-G LED Flashlight from Amazon.
Is this a decent idea? I'm willing to be talked out of it.
My primary light will be a stock B-M generator-powered light, but I want my secondary light to be excellent.
