Whyâd you have to go and be all nice about it? Here i was highly caffeinated and ready to send a dozen papers your way haha.
No but I calmed down on the drive.
Hereâs a couple relevant papers:
discussing vibration on cells /spot welds:
https://books.google.com/books/about/Lithium_Ion_Battery_Failures_in_Consumer.html?id=TVSzDwAAQBAJ
Hereâs on vibratins effect on sheer strength:
The vibration thing is very well documented in engineering and academia. Cyclic stresses bring down bridges , buildings more often than single load stresses. Basically after every application the metal becomes stiffer and brittle. So eventually even the little oscillation will cause plastic deformation (permanent bendiny)
That aside, we build our packs to stand up to this vibration. Itâs been the cause of many a fire around here.

Hey what kind of shipping rates are we looking at for australia. If you can ship to me Id be interested in 100+ cells
Looking forward to the cells. Will report back. This my First attempt to build a 18650 battery. I did a few lipo 10s packs b4.
I would suggest you to get some spare cells like 5 extra. firstly to practice spot welding and secondly to have a spare if a cell is not good.
For that price they on sale it definitely makes sense and save you troubles later.

Trying to convince my buddy to build a pack for his ebike rather than shell out for a prebuilt. Watching this thread.

So will you ship these international to australia or not?
Oh sorry, missed your post. I will but youâd have to either buy me a label or send me shipping money directly so I donât have to wait for the hold on the funds to clear off. And figure out if itâs worth it for you, quote the price with my approx. address and yours as final destination through usps and come back to me when you figure out if the price is acceptable to you. each cell weighs approx 47g, with the box adding about 1.2lb of weight.

@dog. Thank you for the super fast shipping. The cells looks good. I have not build my battery yet so I could not testify on how good the cells are but the services is good.
All the cells are between 4.00v and 4.02v. All the cells came from the same battery pack so it looks good.

Thanks @Dog !! Found an easy way to take these apart, and all batteries so far are within .03 volts of one another! Going to put together a 12s10p pack to go into my DS EVO! Woooot! Exited!

So the tabs come off easily? Do they make holes or leave torn little pieces of metal on the cells when you pull them off?

It still leaves little tabs that need to be cleaned off, and little indents from spot welds. But I am not concerned about that

120 cells disassembled and stripped of excess nickel, a few hours of labor but well worth it! Most cells are at 4.06 volts a few at 4v and a few at 4.14 but over all very happy with this!
