I used to work for a major manufacturer of industrial, commercial, and aerospace Li-Ion cells. I have some video I took of the assembly line from A - Z if you'd like to see it. Great vid.
Beautiful! I would LOVE to see you do the same for the EVE 40PL Li Ion cell, which they claim is "tabless". It has a 60A continuous discharge rating, and 3.1 mOhm internal resistance.
That P45B cell definitely had all 3 copper tabs spot welded. The one you thought wasn't spot welded had the weld ripped out of the tab and a "hole" like that is how you can tell if a spot weld was done with enough power. A proper spot weld (at least when doing nickel strip to the cell can) should be removed with pliers (if it can be pulled off without tools its too weak) and the nickel strip should have a chunk of the material ripped out of it that should remain on the can. The material left on the can is called the weld nugget. A spot welder with insufficient power for the material you are welding will leave little dots on the bottom side of the nickel but there will be no true welding of the two materials together. The strip will come off in one piece with only those dots having provided some slight hold on the can.
@@cagmuer Running a couple of their cells through varying CC discharge tests and then comparing those graphs with HKJ and Mooch's testing can very likely identify the cell. Not the easiest way to identify it but if you know common cell characteristics you can narrow down the possibilities to 10 or so cells just based on its max discharge rate and capacity.

I think you forgot to link the original LiPo video like you said, I can’t find it in the description or anything, but it’s easy enough to find just thought I’d let you know (And please let me know if I missed it obviously)
Excellent video, very informative! Question- I had a brand new Molicel P26 spontaneously begin to leak while in storage (3.7v). Any idea what would cause this to occur?
whats the best option for high range molicel p45 or another 21700cell? setup are: 60v with 2x 1400w motor and 40-45a controller. driving between 30-70kmh.
I always used the Sony Murata 25 or 35a 18650 cells, they where always ranked best in the flashlight community. But they are nowadays ditching 18650 cells for 21700 cells.
The flashlight community mustn't have tested molicel cells.. The molicels have been the best performers for quite some time for both the P and M series cells.
@@StarsAtNight1 I think you mean mWh, not Wh. You missed the part of my comment "both the P and M series cells". The molicel M35A is a 3500mAh cell and handles the same current as the VTC6,
@@StarsAtNight1 I know what a watt hour is. Hence why I said "I think you mean mWh" because you did the math wrong. 3000mAh = 3.0Ah. 3.0Ah * 3.6v = 10.8Wh or 10,800mWh. 25lb battery generators have ~300Wh of capacity. If the cells had 10,800Wh of capacity (10.8KWh) they'd be the size of a large fire extinguisher. Molicel (like all other manufacturers) make 21700 and all other standard cell sizes. The internals are the same - just more of it and larger sheet heights. The better performance of the molicel cells is the same on the larger cells as well.
They do.. It's what's in your phone. They're called lithium-ion-polymer cells (sometimes called 'pouch lithium-ion'). It get's confusing because people often refer to them as 'lithium-polymer' cells but they are different (mainly the electrolyte). They're far more expensive and usually can't handle as much output current as the construction of the cylindrical cells allows for lower IR. The casing also works to dissipate heat.
@@ryanokeefe12 i should have said for quads. that would because thats what we are using these vaping batterys for also used for other things as well but not really suited to quad like a phone battery
i like the auline construction better it's somewhat similar to the 4680 with a short current path it's just that little ribbon that connects the interposer to the terminal that's holding it back
Weird, how your hands look sweatier both times it cuts away for opening the battery... Almost as if they're a BITCH to cut? ;-) Thanks for making the effort!

Yes. I would like to see

Yes please!
absolutely yes - thanks

Agreed, but without any labeling on the bare metal can of the cell, there isn't another way to identify it.

manufacturing defect
Thank you for doing this, so I didn't have to waste a cell doing it myself.
Interesting video Chris, Battery Mooch is a go to on all li-ion battery testing
Very informative 👍🏻
Fascinating stuff indeed! Thanks a bunch, Chris! 😃

@@ryanokeefe12I just took the numbers from the website called lygte info dk
@@StarsAtNight1 you arent reading what I'm saying. The cells are ~9-11Wh, not ~9,000-11,000Wh
Why do the people avoid so hard using "joules" when talking about batteries? You know, _the_ standard unit of energy. (1J = 1 W * s)
We all just do the conversation in our heads... J,/K
for batteries everybody uses Wh or kWh. if you want J so bad just multiply by 3600
Is this the one you soldered? If not, it would be interesting to see if the soldering did anything visible to the cell interior.
Great video, who doesn't love lions?
molicel p42a vs p45b is the p45b worth the extra price ?
Is a stronger cell as safe as a less powerful one?
Any possibility for 4s supernova motors????
Good Golly Miss Molly!🤣..yep,they're excellent in my experience.
well done.... aka interesting
They need to make a li-ion soft pack like lipos because the metal case adds a lot of weight
yea
but also rigidity and strength
some lipo manufacturers add aluminium plates on the outside to propect against damage in crashes

it's somewhat similar to the 4680 with a short current path
it's just that little ribbon that connects the interposer to the terminal that's holding it back
spot welding the copper tabs to nickel...to then weld that to the can is DRAMATICALLY increasing IR
