If the sample test works I’ll take 30 large and 30 small. If the test doesn’t look good then I’ll kick in some to help with the sample.

Ok, so now that the sample testing is complete ( Wink ) I’ll take 50 large.

Yes, it worked. Thanks

I found one more battery:

Quote:
Imalent 4500mah 26650. It is also rated at 15 amps. I think it tests at 5000mah.

This was from the L6 thread. As always, just because a manufacturer says it’s battery can do 15A or 20A doesn’t necessarily make it true. I would do a search to see if they have been tested before I bought them.

List has been updated again.

We are at 1666 big springs, and 1182 small springs.

Now, there are actually 20A capable protected cells?

They must be using quite powerful MOSFETs to achieve this, with especially low gate resistance.

Appearantly. Keep in mind that the Acebeam 5100mah 21700 is a high capacity cell, not a high drain. I’m not sure what it’s base cell is, but it’s safe to say it’s not rated for over 10A continous (it might be a Samsung INR21700-50E). The EC65 light it’s used in draws about 15A, but only for a minute or less at a time. The protection circuitry still adds a bit of extra resistance so the voltage sag is greater compared to an unprotected cell. Both of these reviews have interesting battery tests. Maukka’s EC65 review. Toobadorz EC65 review.

Note that the EC65 has single springs on each end while drawing 15A. This light could definitely use these Beryllium Copper springs!

BlueSwordM, I need a clarification of how will the GB go.
First you order a batch of big.
If it’s good, you order small ones too. Otherwise the GB ends without making small ones at all, right?

What will be the delay from one batch to another?
Can you just wait with sending big ones until the small arrive to ship them together for those of us who ordered both?

Good idea, that would sure suit me if it is OK with BSM. It would not only save on shipping cost, it would save BSM a lot of time only having to just do one mailing to each person.

I’ve already thought about it.

You see, I said that the max shipping price INTERNATIONALLY for less than 110 springs would be 5$US.

So, for most people, I was going to wait until I received the big springs first, test them, and if they are good, I would then request the batch for small springs to be made.

That last part however, would need to be payed for by you guys and gals, since my hobby funds are almost empty by that last purchase.

However, for some people who ordered A LOT of springs, which are:

- MRsDNF at 120 total springs
- teacher at 160 total springs
- ASF at 200 total springs
- Texas Ace at 140 total springs
- DB Custom at 150 total springs

For these guys, it would actually be CHEAPER to send the big springs and small springs separately due to weight reasons.

TLDR: For most people, I am going to send in big and large springs together.
For the people mentioned above, it would be less expensive to send the big springs and small springs together.

Whatever works best for you BSM first & whatever is cheapest second. Smile

Thank you sir!!! Smile . Thumbs Up

That’s a good lead, I’ll see if I can find them based on that. I don’t use protected either but if there are some really good ones out there I wouldn’t mind having some for testing and sharing purposes. While I don’t normally have someone else using my lights it would be nice to be able to have a cell that could run em as they’re built to run and yet not be killed by someone getting over zealous.

I bought some protected Sony VTC6 Button tops. Cant remember where off tje top of my head but if you cant find it let me know.

I haven’t been drinking(yet)…I swear. Am I just slow or is this explanation not really making sense to anyone else??

Shipping:

- If you have a total of less than 110 springs, it is cheaper to ship small and big springs together.

- If you have a total of more than 110 springs, it is more expensive to ship big and small springs together. Therefore, I will ship the big springs separately for these guys:

  • - MRsDNF at 120 total springs
  • - teacher at 160 total springs
  • - ASF at 200 total springs
  • - Texas Ace at 140 total springs
  • - DB Custom at 150 total springs

Thumbs Up/\ ….. Makes sense to me. Smile

You are in Canada & know what the shipping costs are there. Works for me however you need to do it to keep the ‘shipping cost’ down. Thumbs Up …. Smile

BlueSwordM I’m happy to pay for both the big and small springs now before you order if that’s easier for you.

Same here BSM, I’m with skinny_tie; whatever you want…. Payment in Full, partial payment, down payment, whatever you want…. you call it. Smile

We are at 1741 big springs and 1257 small springs.

The big spring group buy will end once we get at about 1950 springs.

That is the same thing with the small spring: it will end at 1950 springs.

Ok, one last thing before the springs are being made, as the BeCu 1mm wire has been ordered and shipped.

We initially, or rather I initially, chose zinc as plating as that would be the best compromise between cost, mechanical properties, and electrical conductivity.

However, I have thought about using nickel tin for plating instead. Because tin has a lower melting point, it would be easier to solder a bypass to than zinc, if you actually need to haha, and since it is a bit softer than zinc, it would provide about better contact area with the battery, and provide about the same electrical conductivity. And nickel substrate below the tin.

So, which one would you prefer?

A zinc plating, or a nickel-tin plating?
