BLF Interest list for Very High Current Beryllium Copper springs Pt1(ENDED)

Yes, that is what I was thinking. Although I guess the 5th spring would not be part of the comparison come to think of it.

This should push the springs to the limit though, I might need to wait for the dual springs. At max power each spring would need to handle 15-20A.

We won’t know until somebody tries it. :smiley:

Update: I hope you know TA I was only kidding, I wouldn’t want you to weld your new springs
to the bottom of some perfectly good batteries. :smiley:

After testing both battery tubes, then swap the driver spring.

Yeah, there are some possibilities. I ordered some LED’s for the MT09R today, if I get some time I will put it together.

So, other than TA, has anyone received their springs or not?

These still available? Can I get qty 50? Didn't sign up for them, just heard about this.

If for whatever reason you miss out on these here Tom I got enough that I can share some with you if you’d like. :wink:

I have a 50 pc order that I can split with you, 25 pcs. :beer:

I’ll also spare 25pcs for you TomE.

BlueSwordM, Would it be possible to order a batch of springs like this that will fit the switch tower of a maglite?

I would pay for the 2k batch. The dimensions of the spring are

L: 32.76mm
OD: 8.15mm
ID: 6.45
Thickness: 0.83mm

The most critical dimension there is the OD since there are metal caps that go over each end we cant go larger. Any of the others could be adjusted a bit as needed.

Nothing yet, but I am expecting them to show up any day now. :slight_smile:

If the offer still stands i would be in for 20 big springs and 10 small (if shipping is not to much)

I’ve been a little absent looks like everything worked out!

So if I understand it’s 30 cents per small spring + 5% for paypal for US orders?
If so bump my order up to 16 springs and inbox me when you have the time. :+1:

I wonder if it’s too late to ask for 10 of these springs? I’m about to take the leap into modding my first flashlight! Thanks so much.

All 2000 big springs have been sold. There are still some small springs available.

Is there a second batch planned anytime?

Probably after I sell both the 1st batch big and small springs.

I will also tweak the design for slightly higher current using slightly thicker wire at 1,1mm, and a better coating, probably gold if we can afford it.

The main difference would that I would make a 5000pcs batch instead of a 2000pcs batch since I have a battery holder project in the works that could be amazing!

Hey Matt? Will it help to gain electrical conductivity in replacing that spring when the ground is still the long steel contact slider? It only makes surface contact on the outside of that pillar, gotta be losing a lot there. I know it is as I just built up a triple in a chopped 1D and am not impressed with the result, even bypassing that center spring, pretty sure if I rig a bypass around that ground it’ll do a LOT better…

Yes, bypassing that little strip would also help. Part of the reason I want to get the springs is also because under 8 amp continuous load sometimes the factory ones loose their spring. The internal switch contacts seem to hold up better than it. In the fully assembled lights I sell I always wire bypass it but that gets tiresome quick :slight_smile:
