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

Ok for the spring being 1mm taller. No cost difference.

Hmm? Why would you flip the spring? Wouldnā€™t that be the reason to use the small spring instead?

And wouldnā€™t the bottom 9mm diameter be too wide, and risk a short?

True, I forgot about the small spring.

Okay then.

Iā€™m going with the 7mm top diameter, and 9mm bottom diameter then.

Anyone against this for the springs?

I want to make the order quickly before sleeping.

That size sounds good as does a bit taller. :beer:

Order those puppiesā€¦ā€¦ :wink:

Ok then.

I will place the payment with these final parameters:

- Material: C17530 (Beryllium Copper) with IACS of 38%

- Spring upper diameter: 7mm

- Spring base diameter: 9mm

- Spring thickness: 1mm

- Spring height (free height): 13mm

- Plating: Electroplated zinc

  • Total number of coils: 6

Sounds good to me :+1: .

The payment has been sent.

Hope it goes well.

Excellent!! It probably will go fineā€¦ā€¦ :slight_smile:

But, should something go wrong at least you have PayPal on your sideā€¦. hopefully. :wink:

Now, the harder step will be Canadian customs.

But it should go well too. Theyā€™re only springs, and they didnā€™t react to an order of 350 Fasttech Springs, so it should go fine.

Iā€™m going to be calling it a commercial sample, since technically, for springs, it is a small order :beer: :smiling_imp:

UPDATE 6

Payment sent, and order has been started. Letā€™s get this GB ball rolling.

1. 1mm wire BeCu C17530 38% IACS has been ordered.

Can I get in on this?

Iā€™d like 50 please.

Thanks!

50 big or 50 small?

Anyway, I will go to sleep.

See you tomorrow!

50 big AND 50 small

Thanks for making these available!!

10 small, 10 large springs, thanks!

Nice work BlueSwordM. :+1:

Protected batteries with high current springs? :confounded:

Itā€™s not ideal, but there are protected cells with 15A and 20A circuits.

Where Jason, links pleaseā€¦

Acebeamā€™s high drain 18650 and 21700 batteries are protected and do more than 15A.

I donā€™t have time to look them up right now, but Iā€™ll try to remember where I saw them.

I think it was the 18650 from Imalent that did 15A which uses a 30Q.

Then the 20A was a 21700 5100mah from Acebeam.

Then I think there was a 26650 from Orbtronic that was 15A.

I think there were a few more and I know I wrote them in a thread, but I canā€™t remember where. I wish I could do a search for things I wrote across all the threads.

Iā€™m not particularly into protected cells, but Iā€™ll try and find the others later today if your interested.
