Thanks - yep having done that entire process on the previous light was going to go through it again.
However happy news - it just seems like it in turbo mode it cuts out on one protected battery but not the other. One can go to 7 and hold it, one goes to 7 but cuts out after half a second - I assume it’s tripping something. I can step back to 6 and it’s fine.
On mine it does turbo for a moment then cuts out - but I can instantly switch back to level 6 and it works so not sure if that resolves whether it’s the protection circuit or not.
My understanding is that when protection kicks in then the battery is dead until the circuit is reset. So it doesn’t sound like your issue is due to the battery’s protection circuit tripping.
It probably depends on the protection circuit… For what i’ve experienced with a few lights and batteries, when the protection kicks in, it does reset by itself as soon as the light is turned off.
This happens to me with the TrustFire mini 01 and 02 for instance, using fully charged TrustFire protected 16340. On high the light blinks at full once quickly and then shuts off. Turning the light off and on again,the light comes on in mid mode. Once i’ve cycled back to high it blinks and turns off again. Once i’ve managed to drain a bit the battery on mid for a few minutes, then it can hold on on high. FWIW.
I read through all BLF A6 threads, but did not find anyone with the “problem” I have. Banggood made it right, just want to share, maybe someone else will get lights like mine.
The tail cap of my A6 does not screw in fully to the body tube. There is always a small gap, which I think should not be there. I can touch the O ring with my nails in the gap. Actually I thought the body tube was too long, but after ordering an Astrolux S1 which has an even bigger gap, the culprit must be the tail cap incorrectly machined. It is even worse on the Astrolux, which interestingly has a slightly different machining at the end of the body tube, and a smoother anodisation.
First one is the A6, second is the Astrolux S1: http://imgur.com/a/2Jdf9 (sorry for the crappy pics)
Actually, the rubber switch of the S1 protrudes a little from the button guards. Maybe it is overtightened.
I am using Samsung 30Q flattops, they are standard size AFAIK.
The pictures look ok, I checked the tailcap of my Astrolux (don’t own the Blf A6) and even after loosening the retainer ring the tube fits - my retainer ring has a smaller diameter than the inside of the tube. But what I see in your first picture: the knurling of tailcap and tube looks different, with my Astrolux it’s the same. Are you sure the parts belong together?
Good question. Never noticed the different knurling, as it is not so pronounced in real life than on the photo. But it makes sense as the tail cap has a bit different anodizing than the body tube. I received the light like this. Maybe the tailcap is from a different unit, switched at the factory.
