Nah, especially since most of our lights already include the protections, the most important ones being reverse polarity protection and low voltage protection, which the S21A already includes.
So, no, there are no safety benefits, especially since you use quality light(S21A) and a high quality charger(Miboxer C4-12 Upgraded).
That makes sense. Does LG or Samsung offer some options that are protected cells for comparison? I don’t mind paying a little more for peace of mind. I just need one that isn’t re labeled or has a very thin one to fit this light it looks like.
I think I would rather have cells close to 5000mah instead of 4000mah. Otherwise I’m not seeing a big difference from my 3800mah 18650 cells. Convoy offers the S2+ in 18650 in almost the same brightness of 1800 lumens with the same LED as the 21700 option.
Do all the lithium cells have less capacity the more output they have?
