Hey YouTube this is going to be just a quick video I went out and did a bunch of hunting
around on my local want ads online and just trying to see if I can find some 18650’s
and I found a huge haul and it's well huge I guess it's all relative but it's going to
be I was able to pick up about 2,400 cells for a really good price and I turn around
and I sold some to a friend of mine and he he's doing some projects and I'm going to
share those later on but he's been using them for his things and I have kept several hundred
for myself I've sold a few to others but for the most part I have probably about 1,500
cells remaining that I'm processing right now you can kind of see them back here and
just going to take them and see how they turn out most of them are really good cells they're
brand new and I'm having very good luck with them so I'm just going to share with you a
little bit of what happened when I went to pick him up and I have video of as I returned
home and my truck full of 18650’s pretty cool so let's go take a look at that and we'll
come back and I'll show you the cells and how they actually look individually so let's
go
I just wanted to show you a find that I did this while I guess it's been a little bit
ago but I found by going online and and hunting down cells was a local classified ad I ran
across these 18650 cells that were being basically kind of discarded and so I was able to pick
up several cases of these cells and I'm going to be processing those I'm actually pretty
excited about being able to have quite a few cells but it really good deal on them each
cell has its own charge controller which is kind of unique so anyways I'll talk more about
that they're all brand new these are brand new cells they were part of a medical equipment
project that basically got scrubbed and so they were just trying to unload all of these
18650 cells that they were going to use for their for producing this medical equipment
so anyways I got to be a beneficiary of some brand new cells they're rated about 2200 milliamps
so they have a little bit of juice they're not you know awesome awesome they're not 3000
a good price and I'm very very excited about him so I just want to point out that if you
put forth a little bit after you can you can go and find all sorts of cool deals but looking
online and and take a little extra effort to see what you can find so several hundred
here pretty excited about it so hopefully I encourage you to look locally and see if
you can find cells that are brand new.
The Harvest them I mean the skins off and I still want to do testing on I want to make
sure I keep my Pax consistent I want to look for any bad cells but other than that I'm
pretty excited to have a whole grouping a brand new cells so tell them we'll talk to
you later
I'm just wanted to go over these cells I apologize my autofocus on my camera May kind of go all
over the place but we need cells came in they got this the skin on them that actually it
wraps them or in compasses and completely they have these three wire leads and what
I found was I know that the red and the black or if you're positive and negative and I think
the white went to the the device that they were whatever they were testing on as part
of the charge controlling piece of it so if I take and tear off the this outer jacket
inside we end up with a made in Japan by Sanyo they are UR18650FJ's and they're brand new
cells that are rated at 2100 milliamps and these charge controllers that are in here
they're more of a charge protection than anything and I'll have some close-up photos that you
can take a look at these charge units that just control the flow I have done some testing
with them and tried to see if I can get them to act as a no like reverse polarity or an
overcharged and they didn't seem to do a whole lot so I'm not hundred percent sure it may
have to do it this white wire and the device that he was plugging into so a lot of this
stuff here is really unnecessary for what I'm using them for they are just spot welded
in the place and it has like a little gasket here to protect it but it's clean cells are
brand-new Samuels and that's exciting within itself so when I stripped those down and get
the powder jackets off of them then what I end up with that I tested and they actually
doing really well I was really surprised here is the resistance on the column and I've always
just use laptop batteries and they've always been around 300 and 400 I think it's Milliohm
(mΩ) using one of those iMaxB6 what the resistance is in the cell but this these here been testing
out from 200 I even had some there down in the 100 so they have very low resistance this
cell itself after being charged up to 4.2 volts it came out at 2168 milliamps so that's
a good good cell and then I'm also working on a process because I like to make things
look pretty you seen my or my power at my portable power pack and this is an idea that
I'm working on right now as well this is a clear jacket and I just bought some just to
see how they turn out I actually like that Chrome look and so I'm going to be playing
some more with that and hopefully we'll have some have some good video to show the Chrome
pieces so the pieces that I removed from several different cells here's what they look like
on the backside of this is one that I just pulled off I'm not really sure if anybody
has any ideas of what these chips to use for I've Googled I Googled and I have been able
to find anything that gives me any indication as to what they're used for other than they
seem to be a mosfet that would help deal with you know like overcurrent over voltage constant-current
constant voltage but I have not been able to find any details on that so if you have
any information on that I'd love to hear about it the same and then this other one is different
so you guys know what they are great to know but I have literally hundreds of these I have
problem when it's all said and done I'm going to have no maybe 1500 1800 of these have done
so far and I have other battery packs them turning into as well so I just wanted to show
you the cells that are really cool and I'm glad that they're brand new that they're heavy
and I like that you're not overly heavy but they're not cheap cell heavy so we'll see
how these turn out I getting ready to start building building them into a power rack alright
I don't have much more to to share here I appreciate you watching.
