Thank you for choosing to download the ham Radio two point zero audio podcast rip.
This is the audio taken out of a video or a livestream I did
recently. You can catch all my videos on YouTube ham Radio two point zero
and catch us live every Sunday night at seven pm Central Standard Time for a
different topic each week. Thank you for the support, and thank you for
being a member of the community. I got a new battery from tem got
t E m g ot that's the way it's pronounced. It's got a really
really cool screen on the top of the battery. Twelve volt's one hundred amp
hours lithium iron phosphate battery. We're going to take a look and put it
on the tester today. Okay, this is the battery right here, and
what I want to do is show you the overhead. This is the Amazon
page that they sent me. They also have a website of their REALM two
hundred for one hundred amp hour battery is cheap. That's that's really good.
And you can see the screen on top of your right there, which I'm
gonna show you here in a second. So I'm curious to see how this
is. This thing is going to perform we're going to put this on the
West Mountain Radio CBA five battery testing device in software and see how it performs.
But before we do that, I am going to show you. Okay,
so I got I gotta zoom nip on the screen. This is a
strap on the top of it here, kind of nice, nice strap.
Like most lithium lithium iron phosphate batteries. This is not heavy. It's not
very heavy at all. But we can turn the screen on right there,
right there boots up for a second. And as of yet I don't have
I haven't figured out how to turn the screen off. It goes off by
itself after twenty minutes a half hour. I haven't actually timed it yet.
But but right now you press that button to turn it on and it shows
you know, ninety nine percent stand by right there, It shows you thirteen
point three volts, the temperature and celsius. You might be able to change
that, okay. The next screen over shows you the input and output or
the max temp. Okay, so you can probably change that max temp and
the minimum temp twenty dot eight degrees celsius. I don't know what that means.
How many recharge cycles I like it when these batteries give you this information
how many how many times it's been recharged. That way, if you I
don't know, if you buy a used battery, you can look at it
and see that, and if you have the battery on your RV or in
your battery box or something like that, you can see how many times you've
recharged it. I like that information. That way, you know how much
longer the battery is gonna last, okay, And it would give us information
there if it was plugged into something right now, and then this I'm not
sure what that screen means right there, it says page three on the bottom.
I don't know one, two, three, and four says thirty three
hundred and twenty six or twenty seven millibles because it said there's four lines there
and then it comes back here. But if you go to the cycles,
it's only on one. So maybe that's just a testing phase they had it
in. I'm not sure. You can turn that off and on, charge
off and on, discharge off and on, so you can turn the battery
off and on by touchscreen that tells you the top one tells you the current
current, tells you the right now voltage and the right now temperature, and
it says nine ninety nine hours and twenty four minutes until empty. That's because
there's nothing drawing on it right now. I charge this battery about a week
ago. I wanted to make sure it had a full charge for I put
it on the tester, charged it a week ago. It's still at ninety
nine percent. So hats off to the ability for it to actually hold a
charge for a long time with nothing drawing from it. So we're gonna put
it on the West Mountain Radio software right now and see what happens. All
right, This is the West Mountain Radio CBA five software that is running on
the computer behind me. All right, so we got new test and test
name and gonna put to tem gott okay live pot four. I'm gonna click
on detect Okay, detects thirteen dot three volts at one hundred empowers with four
cells. The only thing it really detects is the voltage, and sometimes it'll
change the cells, which is usually wrong. But four cells is correct and
one hundred empires is correct because that's what I tested last time. So now
cutoff voltage is ten. I guess that's probably okay. You know, I
wish I should try one of these tests that the cutoff foldage of like eleven
dot two, because anything less than that is going to not be viable and
ruin your battery unless your battery has a BMS. Okay, and a lot
of these tests the battery BMS cuts it off long before it gets down to
ten bolts, So that right there is probably fine because this battery does have
a BMS. Let's go ahead and click on start. All right, it's
running right there now one hundred amp hour. One hundred hours is about four
days. Four hours. Ninety six hours is four days, so I'm gonna
have to come back to this test four days from now, Happy Thanksgiving.
That's about when I'm doing it. Right now, it looks like it's reading
about it's drawing about zero dot eight eight amps. Okay, so it's set
to draw one amp, and when it first started, it'll it's drawing zero
dot eight eight amps, so not quite one amp. So in theory if
it stays, if it stays at that current, it should last longer than
one hundred amp hours. We'll see, stay tuned and we will be back.
All right. We are finished, and after about ninety about ninety well,
actually no, a little under four days. It looks like right here,
all right, it looks like we've got ninety four amp hours out of
this battery. And I will share a couple of screenshot overlays here. I
took pictures of the top of the screen while the battery test was going,
and it was showing the draw in the battery, and it was showing how
much amp hoers was left. So again, the screen is really cool.
I think it's a neat feature to have that screen like that. Now,
one thing I will say is it looks like the test cut this battery off,
not the BMS. So it makes me wonder if there's a BMS actually
in this battery at all. I might have to check with the company and
see. Let me move this a little bit over here, okay, so
you can see right there where it ended. Like I came in when it
was like basically right in here where my mouse is right now. I came
in and it was like the last thirty minutes or so, maybe forty five
minutes before the test ended, and it was down actually it was more like
right here because it was down below like I would expect the BMS to cut
it off somewhere between eleven eleven point five volts, maybe like eleven point two
volts something like that. It didn't. In fact, the software was set
to end the test at ten point five so that you don't bring it down
too far, which a BMS should keep you from doing that. So it
doesn't really look like the BMS in this thing is working. Or maybe it
just doesn't have a BMS. I'm not sure. I may have to check
with the company and see, but let's assume let's assume it doesn't have a
BMS. I think that I would probably take this thing and say, you
know what, I'm gonna put it in a battery box and use it for
a while and just kind of see how it performs over the next three to
six months, because what else am I gonna do with it? Now that
I've done the test on it, and I'd like to see how it works
in a real world environment. I certainly like that big screen on it.
I like the big screen, the big readout on the screen, be able
to look at it and see what's it gonna draw? How much longer have
I got before I have to have to charge it or something? Before it
gets down to like eleven volts or something, because like, you're not gonna
want to run a radio less than like twelve volts twelve point zero. When
it gets down to like eleven point eight or lower than that, the radio
does not operate correctly, so you're not gonna want to do that. It
might be even more, maybe like twelve point two. I mean, optimally
it's supposed to run on thirteen point eight bowls, but we'll see. So
I'll put a link in the description low you guys can go look at this.
I'm gonna also email the company and say, hey, should this thing
have a BMS because it doesn't look like it's working. If so,
