Not sure if I missed it but MTN electronics can only send 4 batteries per order I think just in case you needed more. I currently have some coming from banggood and a lot coming from FT via surface. I figured if I was going to have to wait a while I might as well make a decent sized order.
Will probably order some from MTN in a couple of weeks but I think I have spent enough for this week!
I just picked up another 10 Blazars off Yass like an hour ago! Awesome feller, highly recommend paying a bit more and buying off him, and these ones also have the really good protection circuit and are 68mm long.
All my batteries have come from Illumn and I've never had any issues buying batteries from them. I just received 7 batteries (4x18650, 1x26650, 2x14500) in 2 weeks from the day of order. Their shipping prices have gone up but their product prices are good and I feel comfortable ordering from them knowing my stuff will show up!
Found these copper shims, almost perfect for our applications if you need to shim up your copper MCPCBS with another layer of copper. Relevant diameters are 20, 25, 30mm in .7 and 1mm thickness. They are under a $1 each although postage may kill it. Still beats cutting and filing which is tedious.
Supersports600 (Yass) is a great guy to deal with. I live near him so he let’s me pickup from his place and have a good old chat and he does good prices.
Wish I saw this sooner, just bought some 20mm square ones from Ebay. Bit cheaper, but like you said will require some filing to fit. Picked up 5 of the 0.5, 0.8, 1.0 and 1.2mm so I can do some work on focusing dedomes. $3.50 shipping is good, might pick up some 1mm spacers for the Yezl.
This Ebay seller seems to have 30mm for a decent enough price. I feel your pain, looked this up a while ago but I only have one 26650 that I want to take the protection off, so It was cheaper for me to buy an unprotected 26650. :~
