Hello Dear friends,

Sorry for the delay, now we give a solution for S42 problems：

After Verified by the manufacturer,the length of the tube is too short and it can’t compatible with most length of 18350 and 16340 protection cells and button top cell, the manufacturer adjusted the tube length and they verified the 40 mm tube will solve the problem and allow most cells to be used without the danger to damage it, including the 18350 and 16340 cells. At the same time, they also modified the design of the USB silicone cover.

Any problems, please contact our CS, we will send you a free 40mm tube and USB silicone cover, you can replace it yourself. Please send E-mail to cservice@banggood.com, don’t forget to include your order number, thank you.

By the way.S42 and s42s will use 40 mm tube and the latest USB silicone cover. The s42 now has been sent back to the factory repair, thank you for your understanding and support, we will try our best to do well in the after-sales service.

Best Regards,
Banggood Flashlights Team

Hello all,
I have just received mine today, exactly one month after purchase. While I was able to get it working with the shortest 16340 battery I have, mine has a different problem. After turn on, long pressing for turbo makes it flash quickly and then disconnect from voltage. Breathe light turns off. Unscrewing and re-tightening tube restores function. It displays the same behavior when short clicking. Once it reaches turbo the same short flash and voltage disconnect happens. Very disappointing. Battery is fully charged efest purple flattop.

184

Maybe the cell has too much voltage drop on turbo, bringing it below LVC?

185

That may possibly be the issue, but the #$^$ short tube won’t let me try any other 18350’s or 16340’s I have!

186

Yeah, it was a pretty horrible execution on what I was really hoping was going to be an awesome light

187

Thank you for the fast response Banggood. :+1:

188

dont forget the 18650 tube, I ordered this one and it is too short as well
and it dented the cell so I cut the spring a bit shorter

189

Is there any way to change/fix the UI?

Was your 18650 cell protected or unprotected?

190

unprotected with 3mm thick brass button

191

This battery length/tube issue reminds me of the UT01 where i almost broke the light and dented the button of a cell… One easy way to alleviate the problem, at least temporarily is to add a couple copper ‘rings’ inside the tail cap, where the tube connects. The oring will likely be exposed though.

Such ‘rings’ can be made of a short section of copper wire wrapped around something about the same diameter. You can use tin foil too but it would likely not stand the high current on the S42.

192

Paper clips actually works pretty well too.

193

I had a few flat split-rings that came with one of my lights that fits pretty well in the the tail-cap.
Works a treat for now.
Thanks!

194

I got a nice assortment of copper washers a while back, recommended here, so just had to pick one that roughly fit in the tail - pics posted a while back. I'd say it exposes about 2/3 of the o-ring.

195

well, I sacrificed an Efest 800 to the Krunch God just so I could try this beast.
kinda disappointed that I could handhold it, even recycling turbo from time to time. :frowning:

now with the spacer I can use my WindyFire 700. whole different animal.
terminated the first finger test due to familial duties….just a few minutes
came back and within a minute, I was uncomfortable, and crying like a baby a moment later
seems to my finely calibrated, elderly thin-skinned hands, that the hottest point in the whole danmed light is the switch ring
great engineering there! :person_facepalming: and I gotta hold it for a long press to off? :person_facepalming: :person_facepalming:

I’m glad I got a chance to see this in its potential before my Aspires arrive.

196

Update:

Dear friends,

We already asked one colleague to deal with S42 technical problems specifically, any technical problems, please send E-mail to heyanqing@banggood.com directly from now on, sorry again for the inconvenience and thank you for your understanding!

Best Regards,

Swi

197

Thanks Swi for the followup. :+1:

198

This is a good idea, as customer service did not know the problem :open_mouth:

Will the 18650 tubes for the S42 also need replacement please?
(mine order has shipped but is not yet delivered)

I also asked for a replacement for my new 18350 battery that the light has crushed…

199

Yeah, I’d like to use 18650s without the cell being squished and damaged.

I received the S42 today, and although I sent the mail for a new battery tube and USB cover, I just wanted it to work.

I first measured the Aspire 18350 battery that I want to use, it is 34.6mm. Then I measured the inner length of the battery tube, from the driver board surface to the rim (that is screwed against the flat machined inside of the tail section), it is 36.8mm. So the battery actually fits and I have 2.2mm leftover. On the battery side I used up 1mm of the 2.2mm to solder a bit of brass as +pad for the battery (the spring was removed). On the tail side I shortened the spring and carefully re-shaped the remaining coils so that they compress inside each other instead of on top of each other (carefully because the tail spring seems a copper alloy which is likely more brittle than steel). The whole spring now fits inside the tail recess when compressed.

Now the Aspire battery is a perfect fit, with 1.2mm leftover, so a slightly longer battery will fit too.

Further impression: nice size and looks, great output (XP-G3 version), I actually like the tripod mount and don’t mind the extra length that it takes, I hope the USBport-cover will be replaced with a better one, and the hopeless UI is the great showstopper for this light.
