Finally received mine. First Impressions ... pending longer runtime tests - pure basic function test at this point.
BE VERY AWARE OF ...
The issues to be AWARE of BEFORE you buy so that you prepare for it. IF you plan it is NO PROBLEM, but if you don't plan due to the lack of information of their website or manual, then you will get in trouble quickly.
We all expected this, so it is not a complain and found a solution, will my pre-existing 18650 batteries work?:
(A) Eagtac 3400mAh which are PROTECTED at 4-6A.
a.1 EXPECTED RESULT1: As reported in this forum, but now confirmed now in person, works fine to all modes but the MAX2 (the 2000+ lm) - that trips the protection after 1sec. If they documented this on their website and manual, I would not have a problem with it.
AT, come on, the above, although not unreasonable given the fact MAX2 needs more than 4A, in my opinion should be WARNED in their website and in their manual as not all users have a MS in EEE.
a.3 BIG UNEXPECTED WARNING: Here is the issue that you NEED TO PLAN BEFORE HAND, and on that I will not give AT a pass as I did above: WARNING!!!! After you trip in MAX2 a non-optimum protected battery, you have to unscrew all the way and back ... but here is the real problem - the light gets stuck in the last mode of MAX2 ON! Why is that a problem? well, maybe I am missing something, but after my first tests got the expected MAX2 tripping the battery protection, you are STUCK in MAX2 Turned On in the light the moment you reinsert and screw in the battery which means that unless you have an unprotected battery or a high drain protected at hand, you CANNOT get the light long enough to use the UI to toggle back to MAX1 or other working modes. Maybe there is some secret UI thing, but really you will never get that far to use the UI so ... that is a BIG NO NO ... as if your only battery at hand is the one you used, then you are dead in the water ... They should correct that by detecting battery driven power cut and not memorizing the last mode in such condition by switching to a different mode maybe .. no excuse. Still, if you know this, you just use a different battery ... but this is going to catch a lot of people and will make them fume in forums while they get the right battery. Of course we need and like auto-memory but only if NOT power tripped last.
NOW THE GOOD NEWS
(B) Fortunately, expecting the Eagtec to be borderline for protection based on reports on this forum, I had ordered Orbtronics 3500mAh featuring higher 10A protection circuit.
b.1 I inserted one and was able to support MAX2 no problem, and finally use the UI to switch it down. Then I could use it again with the lower drain batteries if I wanted, ... but will never do that since you run the danger of getting into MAX2 and getting stuck. So basically, never use any other batteries that high drain with or without protection.
b.2 I have not run them for a long time, but all looks that you can run this PROTECTED batteries as a perfect partner for this light MAX2 because they are rated at 10A protection. Still, let me run a full run test next week and I will confirm that the battery model is the right choice, but they look like they are after running them for few minutes.
FIRST IMPRESSION/CONCLUSION
GREAT BEST OF CLASS light, ... if partnered with the right battery (only 10A protection or unprotected). I prefer the extra safety of using protection at subcomponent level. Still, having a user case in which you can get stuck with no way out by simply using a slightly less optimum battery... makes any battery other that the 10A protected or unprotected NOT suitable to use. They should state this IN BOLD RED in a new manual and in the website.
At least I did my home work and got the batteries that seemed to fit the need. So I am A-ok.
Anyway, for me, with Orbtronics batteries (by the way - I am impressed: they shipped PERFECTLY, with a perfect storage box ... great company - they just won a customer for life). If they work in longer run tests next week will report here - PERFECT flashlight, but it is a petty that for not documenting the above and having a use case that could get stuck in MAX2 they don't get 10 of 10 score, if the above is fixed, then I will give them 11 of 10.
Great choice, but BE AWARE of getting the right battery at home BEFORE you received it.
Will report how well it runs with long use and confirm or not 100% that the protecting orbtronics are the right match.
