Even where NiMH make more sense?
Sure, you could stick in one 14500 cell, and 3 spacers. It would probably work. :shrug:
I think you are misunderstanding me! I understand that they[L.Ion] can not be used. For me it is not about trying to get L.Ion to work because they are NOT intended for these types of lights.
I just do NOT like the Chemistry of NiMH and how difficult it is to get a full charge using multi-chargers. In addition they[both AA and AAA] have lost capacity while not in use much faster than my 18650's.
I only HAD One[1] 4 X AA light. I was not going to buy a charger specific to NiMH just for my EA4! Later on I got a AAA light for my car. Same results,,difficult to get a full charge and batteries lost capacity too quickly while being idle.
I have only Two lights[Modded] that take 16340. I do not like them much either but I LOVE the power of my D25Cvn and PD12vn!
That leaves[yes I am a flashaholic!] 37 lights that take my favorite battery,,,,,,18650!
I am just not a fan of AA or AAA batteries. A single cell or Two cell 18650 can be just as compact if not more and deliver a lot more power! Example: My SC62. Much more compact and puts out ~1000 lumens!
Going in the other direction[Throw] I have a SWM C20Cvn that is ~600 lumens and 20Kcd. Single cell 18650 just like the SC62!
So, without taking anymore from this thread,,,,,,,,,,,that is it!
