Thanks but the akku Work in my other Flashlight.
Bangood will send me also a new head.
Now ist Time to wait.
Ask BG to test the head before sending it to you. They process the order very slowly, Iāve waited 10 days before the they send the light head. Still waiting.
Ok i will, Thanks Ingeve, Hope the head arrive you soon
Hello Ingeve Please write when the head arrive and Work, i still wait.
Still waiting. When I arrive I will share impressions.
Today I got my head and the flashlight works finŠµ.
Perfect i still wait
Please make sure you removed the rubber O-rings. I couldnāt get my Astrolux S42 to work until I removed the two rubber O-ring.
this makes no sense the o-rings have nothing to do with the current conducting surfaces
Those of you that have defective heads, do you want to sell them to me when your replacements have arrived?
I would give it to you as a gift, but I already sold my flashlight with the head.
Thanks. Still got a chance with balinzwerg though 
My head arrived Today, the Flashlight Works Perfect.
@ Mike, sorry i will try it on my One to find the Problem with my head. I Think Porto to Sweden is to much for an 20 Euro Flashlight.
Itās probably less than 20ā¬ and I could use the parts. No worries though, just let me know if you change your mind. I can paypal porto costs prior to sending.
Ok i Think about it
Could someone please mention why, or post a link for the reason to use unprotected cells in this light?
Thanks
Because current consumption on turbo. No protected 18650 can deliver 18A.
Mike
Thanks
Hi Guys,
I also get the same problem, I am using unprotected batteries. But after unlock (green light), my first click is turn off it.
I also report to Banggood and they seem dont want to support anything.
