I need to get some 26650s for the incoming D4S, ideally bought in the UK
I cannot find a UK seller for the LiitoKala 5000mAh 26650 cell (I don’t count un-recommended sellers from e-bay or amazon), but I can find UK sites I would be willing to buy 26650s from, for:
I understand the mAh (bigger is better, if all else is equal I believe)
But I don’t understand the Amp requirement for a D4S, and the description for the above cells (e.g. (20A/ 75A)
Would anyone be able to recommend some cells? I presume I’m going for unprotected flat tops.
FWIW, even with the D4S’s increased thermal mass, turbo is still meant for relatively brief use. Higher-mAh cells work better at the lower, saner levels where the light will most likely spend most of its time. It can, for example, make the difference between 12 hours of runtime and 16 hours of runtime.
Keepower are normally pretty decent. I’ve not heard about this 6000 mAh version before, never-mind the protection circuitry which I would usually avoid, but it might be worth a look.
I installed RealCalc and a few others back in 2011 or 2012, but I haven’t used any of them in years. Mostly I just use python’s CLI as a calculator now. Anything without a programming language built in hardly seems worthwhile any more.
The D4S is bigger. That means longer run times and a somewhat longer time on Turbo before the light ramps down. It has the aux lights which are both cool and useful.
Most of all, it comes in green. Green is the best colour for a flashlight ever.
You need both. Better order that green one now before they are out of stock
(Seriously of course you do not need both. Save your money. oh and don’t tell anyone I said that)
Awk is an ancient programming language created for processing text files. A very short awk program can do some tasks that would take pages in C or Java.
Maximum battery length that D4S will accept is 69mm, according to specs, if that helps.
The length of that KeepPower cell on that 18650.uk site is listed as 60.3mm, which is obviously wrong.
I still like Droid48 when I’m not at a computer for a quick calculation.
My 11C got me through my senior year of HS, and all of college. As an “accepted into grad school” gift to myself I bought a 48G, and I just barely used it enough to get accustomed to the UI.
