Anyone replacing an SC600w MK III with a HI?
Btw, I don't see it listed in stock at any stores at the moment.

Question - what are the risks/concerns regarding charging unprotected 18650 cells? I have a Nitecore D4 charger at home...
Kinda an impulse buy, but I ordered one at the ZL dealer here. Should arrive tomorrow. Will see if I like it.
Package received but the standard version was shipped there goes the fun..
The dealer sent you the regular MK3w and not the HI version? Bummer to hear that happened Hopefully they'll make things right for you! The MK3 HI really is an excellent little light and now my go to ZL.

You should purchase an unprotected NCR18650GA from illumn. If you don't like using unprotected cells you could return your flashlight.Can someone please clear up the battery confusion surrounding this light? Protected? Unprotected? 3400mAh? 3100mAh?
I just got mine in the mail only to find out my batteries don't work with it.
They are branded AW IC and have a red stripe on the label, 18650 3100mAh.
Thanks for the replies to my question... I still feel a bit nervous/apprehensive at times about the Lithium-Ion cells and their usage (currently only using 18650/16340 protected cells in 2 of my Olight flashlights)...
Does anyone know if the beam profile on the SC600 is similar to the SC5? Or distinct/different? What I like about the SC5 beam profile is how the hot spot diffuses/blends well with the spill... On other lights, when there is too much of a defined hot spot that sharply contrasts with the spill (I can find it to be distracting on my eyes when shining the light)...

Hey!
Zebralight actually responded to my email about where they source their parts from! The MkIII actually is mostly made of US sourced parts. This is the response they sent me. Vishay has manufacturing plants on 3 continents and Israel.
Subject: MkIII Electronics
Here are some of the major components and materials in the SC600 Mk III (HI):
- one IC, from Dallas, TX based Texas Instruments
- the rest (3) ICs, from Chandler, AZ based Microchip Technology
- all (3) MOSFETs from Shelton, CT based Vishay Intertechnology
- one inductor from Cary, IL based Coilcraft
- aluminum bars from Foothill, CA based Kaiser Aluminum
- glass mostly from Corning, NY based Corning (over 80% of the lens in the flashlights and headlamps we produced recently are Corning Gorilla Glass 3. You still have a 20% chance of not getting the gorilla glass though)
- LED from Durham, NC based Cree
The most important part of a battery protection circuitry is the MOSFET. Currently Vishay is the world's number one brand in the low voltage MOSFET field, period. The MOSFETs we use in the SC600 Mk III as well as all of our other lights are some of the best from Vishay. I don't know any good 18650 protection ICs/MOSFETs from Japan. There are some so-so but cheap protection ICs from Seiko that are popular in China, but you won't find them in any high performance li-ion systems. One problem in the current 18650 protection scheme is that the protection board is a separate entity, next (at the -end or +end) to the battery. Wires connecting the protection board and the battery could be damaged (or even shorted) from drops, punches, or cuts, etc., because the thin plastic wrapper is just that, a thin plastic wrapper.
Hope this clears some things up for folks. I am greatly pleased by ZL's prompt and detailed reply!
Capacity isn't a factor, only physical size. In short, however, most any flat top unprotected cell will work.
.. almost completely down. ...
That's why. The electronic path isn't complete. The battery tube needs so contact the pcb-board in the tailcap.
Isn't contact with any of the threads completing the circuit?
