Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light

Just received my VTC6’s from GB. They are dated June 2016 (C6AYF16J), which I think is not an issue.

Now. My. want. da. flashlight.
:slight_smile:

Unfortunately the stronger the steel the higher the resistance of the material usually gets.

Would it not be easier or simpler just to change the length of the inner spring, to make or keep contact with the outer spring, the little bend on the outer spring would act as a keeper, to contain the inner longer spring. Sorry if this has been already suggested.

As I understand, the spring steel is not conductive - it's the coating on the steel that conducts. I've smoked springs before, and the coating is what burns off and the remaining spring steel doesn't conduct well at all. I've even taken off the coating with a soldering iron - same thing, where the coating is off and get no conductance.

Hehe what kind of high did you get from smoking the springs :wink:

The Miller could you put me down for a 3rd one? Thanks!

That’s the definition of a sunk cost. People have great difficulty letting go of those, but it’s important not to let them tie you down to sticking with a bad decision.

Looks like the rush to get batteries is premature…

That’s true. But, in this case, I happen to think shortening the tube is a better decision in almost every way, and the “sunk cost” NOT becoming an issue is just one of the many reasons. :innocent:

Asked Thorfire if the smaller of the double springs can be made 2.5 to 3m taller so even short cells connect with them both.

mm i hope :smiley:

This might explain the unexpectedly high readings of the protected GA cells tested.

That would make them connect to the ceiling :smiley:

This flashlight is already perfect. I can mod my flahslight and bypass the springs. Can I have it now in this form? I need it now. How about a presale groupbuy for those like me who dont want to wait another month or two (or 3 or 4 or 5) till it is perfect?

This should not take very long
If my measuring is correct 2,5 mm longer small springs should connect having both springs take current and temp.
Or another solution with the springs for that does not require design changes on main parts.

I would just bypass springs so no problem with current and temp.

Is there option to do it in factory?

Maybe n my old SRK, two of the springs were shorter right from the factory. It was easy to work around by putting a magnet on the bottom of those two cells. Maybe short cells should have a similar spacer when used in this light?

Because one of my proto3 springs was toast anyway, I decided to replace them all. The only springs that I had that were the right size and nice stiff were my phosfor-bronze ’djozz’springs, so they went in:

This is how it looks now (VTC6 batteries, same length as 30Q’s) :

The batteries sticking out over the (shortened by a few mm!) tube so the springs are compressed well, and enough travel that long cells fit too.

Because phosfor bronze has one-third the resistance of steel, the out put went up too (not neccessarily what I desired), on VTC6 batteries 6130 lumen now (30 seconds). My 30Q’s are in the charger now, numbers with them later.

Oh that is nice Djozz!
So hope it is good with this solution!

I hope that Thorfire is willing to source beefier springs, my springs btw are 10mm base diameter, 15mm height (13mm after the first compression, it stays 13mm after that).
We could show Barry the above picture with the VTC6 batteries.
