I have had issues with springs not being tall enough but rarely had a problem with it being too tall.
So an extra 1mm height sounds good to me.
I wounder if dropping the top size to 6mm might be a good idea as well, that way you could flip it upside down for drivers that have very small spring pads (like the TA 17mm).
Ok for the spring being 1mm taller. No cost difference.
Hmm? Why would you flip the spring? Wouldn’t that be the reason to use the small spring instead?
And wouldn’t the bottom 9mm diameter be too wide, and risk a short?

True, I forgot about the small spring.
Okay then.
I’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.
Order those puppies……
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
The payment has been sent.
Hope it goes well.

Excellent!! It probably will go fine……
But, should something go wrong at least you have PayPal on your side…. hopefully.
Now, the harder step will be Canadian customs.
But it should go well too. They’re only springs, and they didn’t react to an order of 350 Fasttech Springs, so it should go fine.
I’m going to be calling it a commercial sample, since technically, for springs, it is a small order :smiling_imp:
UPDATE 6
Payment sent, and order has been started. Let’s get this GB ball rolling.
1. 1mm wire BeCu C17530 38% IACS has been ordered.
50 big or 50 small?
Anyway, I will go to sleep.
See you tomorrow!

Protected batteries with high current springs? :confounded:

It’s not ideal, but there are protected cells with 15A and 20A circuits.
Where Jason, links please…

Acebeam’s high drain 18650 and 21700 batteries are protected and do more than 15A.
