Man, I just found your vidia on a Hackday googling for 18650 stuffs. All the vids and articles Ive looked at, yours was the best I found, its not much different from the rest, but your approach to sharing knowledge while doing the actual work, not stopping to explain stuffs Ill forget in two seconds, whenever this happens I find myself skipping back and forth trying to find information I just heard but couldn't see because some smuch thought his face would be more informational???? But you, youre just doing and talking. Serving just the right amount of visual and auditory information. God dammit you deserve an Oscar for best informational video This vid should be the gold standard of tutorials, or any informational video. Someone give this man a medal
Great video not sure I want to spend that much on an on off switch I will stick with an anti spark plug and a cheap switch.. First time I've seen a pack built with all 4 batteries the same group usually there +-+- all the way through got's me rethinking my setup..
One should make absolutely sure (by using hot glue or silicone) that all the cables are properly stress relieved. Soldered fine wire connections are really bad strain point and any movement in the wire will cause premature failure over time to that connection. :)
Even if the pack's and charger's management circuitry will eventually equalise the charge on each cell, would it not be desirable to precisely match their SoC before assembly? Cheap capacity tester boards are available that can be used to do this to within less than 1% (and of course actually ascertain their capacity to similar accuracy - a simple voltage reading doesn't really tell you this).
What is the base copper foil thickness and characteristics, are only ED copper foils used, can RA copper foils be also used, just curious whether RA copper foils are also used in making the anode current collectors : Thanks
“Should read somewhere in the 3 to 4 volt range, if it reads anything else it’s a bad cell” is dangerously incorrect information. Good cells can be 1v and bad cells can be 4v, the voltage has nothing to do with cell health. They need to be tested...

Gan harga baterry berapa?
So underated video, your vlog has the most clear explanation doing diy.
Soldering the main leads off the battery separately then spot welding it onto the battery is so genius I definitely wouldn't have thought of it.
Glad you found it useful! Thanks for watching
You're everything I wanted to be in a hobbyist

Great video Adam, thank you for sharing.
Great work my dude, looking forward to the deep dive!
Thanks!
Awesome videos on your channel mate! I hope seeing some more ev or cnc content.
just what i needed ,thanks ,awesome video
Looking forward to the video of this scooter

Very good point

Really great video. But my corp firewall blocks the mini links.
Do you have any certain value for the discharge rate of the system?

I need help on how to to produce lithium battery for solar
Yes because people that are watching these videos have a fucking spot welder.
“Should read somewhere in the 3 to 4 volt range, if it reads anything else it’s a bad cell” is dangerously incorrect information.
Good cells can be 1v and bad cells can be 4v, the voltage has nothing to do with cell health.
They need to be tested...
Thanks for the feedback! Do you have a link where I can learn more about this?
@@AdamBender Hey mate, check out HBPowerwalls processing video:

@@chrispfeil6605 thanks for the link! Lots of helpful info there
A good cell will never sit at one volt. I personally wouldn't use anything below 3v. I agree a 4v cell could very well be bad though
So how do I make a 56 volt , about 20 ah battery. Yes I’m series for my ego snowblower. Thankyou
15S3P should do it with standard 18650s
What other device can we use as no one carries that fancy machine at home
You could solder the cells, but be careful with the heat, it will damage the cells
Can you make me one
BREATH man.. On each end of your voice comes so low i really cant hear :P
EXTREMELY FRUSTRATING!!! this guy does NOT explain ANYTHING!!
how about if we want a flat design? what about nickle strip size? what about how to join cells in a different way? goddamn
