00:02 - 00:10
So, this is my
00:04 - 00:12
Vaver 48VT 1800 watt brushless motor
00:10 - 00:15
controller motor and controller kit I
00:12 - 00:17
should say. Anyway, these are sold in a
00:15 - 00:19
few different flavors, few different
00:19 - 00:24
wattage, different throttle types. For
00:22 - 00:27
whatever reason, I have a
00:24 - 00:30
uh European adapter and a battery
00:27 - 00:33
charger with this. I I I don't know
00:30 - 00:36
why. The reviews of this are pretty
00:33 - 00:39
mixed. Most people say it doesn't work.
00:36 - 00:41
So why? I don't know. Now, there are
00:39 - 00:43
people that say it works fine. You just
00:41 - 00:46
need to know what you're doing. And that
00:43 - 00:48
I think is key. With that said, I have
00:46 - 00:53
no idea what I'm doing. This is my
00:48 - 00:56
first brushless DC motor slash brushless
00:53 - 00:58
controller slashthrottle slash anything
00:56 - 01:00
I'm doing with this kind of project. So,
00:58 - 01:02
I'm no expert, but luckily I know what
01:00 - 01:03
voltage is and I have a meter. So, we
01:02 - 01:06
are going to dive in and figure out how
01:03 - 01:10
this thing works and if it does at
01:06 - 01:13
all. Going to need a power supply or
01:10 - 01:16
voltage source of
01:13 - 01:17
something. Q in that heavy thing. It's
01:16 - 01:18
actually not that bad considering what
01:18 - 01:27
is. That is an Enjoybot 48 volt lipo 4
01:24 - 01:30
battery intended for golf carts. I will
01:27 - 01:34
surely not be using it in a golf cart,
01:30 - 01:34
but we have a voltage of 53
01:34 - 01:38
volts. All right, browse the
01:39 - 01:43
instructions. Not going to bore you
01:40 - 01:45
reading the whole thing, don't get me
01:45 - 01:50
Uh, so you know, we have that connector
01:48 - 01:52
which hooks up the motor phase wires,
01:50 - 01:54
which are these threes. And then we have
01:52 - 01:56
a hall sensor, whatever that does, that
01:54 - 01:58
plugs in there. It kind of looks like
01:56 - 02:01
the wire colors are all lining up. So,
01:58 - 02:02
that's all I did was I connected those
02:02 - 02:07
using the little included junction box.
02:05 - 02:10
Plugged that right in. And this is just
02:07 - 02:12
8 mm screws that screwed that right
02:10 - 02:14
down. I think these remaining two would
02:12 - 02:17
be for uh battery cables, but we don't
02:14 - 02:20
need those right now. Continue on. It
02:17 - 02:23
shows you what all of the little
02:20 - 02:24
connectors are called, but it also says
02:23 - 02:27
it on the connectors themselves or the
02:24 - 02:31
labels like indicator light, uh,
02:27 - 02:34
three-speed, brakes,
02:31 - 02:35
reversing, throttle. I think they
02:34 - 02:39
mispronounced the key, the T there. It's
02:35 - 02:39
not on there. And then key
02:39 - 02:44
switch. So, the throttle, it shows on
02:42 - 02:46
their manuals the different different
02:44 - 02:52
ones they have. I have this one down
02:46 - 02:55
here. So, you plug it in to the throttle
02:52 - 02:57
port like so. And you can notice right
02:55 - 02:59
off the bat there is kind of a problem.
02:57 - 03:01
These colors don't line up. Now, in my
02:59 - 03:04
world of, you know, automotive
03:01 - 03:06
electrical, red is positive and black is
03:04 - 03:08
ground. Over here, we don't have a
03:06 - 03:10
black, but we do have a red. And that
03:08 - 03:13
red is not going to red. So, right off
03:10 - 03:13
the bat, I do think there is a
03:13 - 03:18
problem. to fix
03:16 - 03:21
that. Going to go in there and get
03:18 - 03:25
myself a little tiny
03:21 - 03:25
pick. See if you can
03:27 - 03:33
see. So, you can see kind of you can get
03:30 - 03:36
in here with a pick and you can push
03:33 - 03:36
down the little locking
03:37 - 03:42
tabs, all three
03:40 - 03:45
terminals, and slide them out of the
03:46 - 03:50
Now we know where red goes. That's
03:53 - 04:01
easy. The other two. Yeah, not so
03:58 - 04:03
much. So, let's go with green. That's
04:03 - 04:07
guess. Put that in the
04:07 - 04:14
middle. Yellow on the
04:10 - 04:14
end. And plug it in.
04:16 - 04:23
All right. This electric door lock,
04:19 - 04:25
electric door lock, uh, red is P+,
04:23 - 04:27
orange is VCC. So, whatever that means,
04:25 - 04:31
the electric door lock must be kept
04:27 - 04:35
normally open. Okay. Or the red and
04:31 - 04:35
orange lines must be connected by short
04:35 - 04:39
circuit. Yeah, I don't know what that
04:37 - 04:40
means entirely.
04:39 - 04:43
One thing that's always baffled me about
04:40 - 04:46
these because I mean this is you know
04:43 - 04:48
probably from China. There are Americans
04:46 - 04:51
in China teaching
04:48 - 04:53
English. Why don't whoever Vaver here or
04:51 - 04:55
whoever is making this because I think
04:53 - 04:57
Vaver just you know assembles the parts
04:55 - 04:59
and put it into a package. Why don't
04:57 - 05:00
they go to one of those teachers and say
04:59 - 05:02
hey will you proofread this? We'll give
05:00 - 05:05
you 50 bucks. you
05:02 - 05:06
know, it would make sense to everybody,
05:05 - 05:08
you know, but they just use, I think, a
05:06 - 05:10
translator app and that's what gets
05:08 - 05:13
printed with no proof reading by an
05:10 - 05:15
American anyway that actually stands.
05:13 - 05:17
That that makes no sense. Anyh who, so
05:15 - 05:19
apparently it needs to be left normally
05:17 - 05:21
open, which means we do nothing with it
05:19 - 05:25
and this whole thing should
05:21 - 05:27
work. So, let's find
05:25 - 05:30
out. Okay, I don't have a connector for
05:27 - 05:32
this, so I whipped up a little barrel
05:32 - 05:35
Hook it up to my
05:35 - 05:42
battery. Okay. Uh, rated controller V
05:39 - 05:45
voltage 48 to 54, which is right where
05:42 - 05:46
we are. Uh, red is positive, black is
05:45 - 05:47
negative. Yeah, that's pretty easy to
05:46 - 05:49
figure out. The positive and negative
05:47 - 05:51
values cannot be connected incorrectly.
05:49 - 05:53
Well, they can
05:51 - 05:56
be, otherwise the controller will burn
05:53 - 05:58
out. Okay, so they can be, but don't cuz
05:56 - 06:00
it'll break it. There will be a slight
05:58 - 06:01
spark when connected, which is a normal
06:01 - 06:06
phenomenon. I don't like the word
06:03 - 06:07
phenomenon, but they could have just
06:06 - 06:08
said there'll be a spark when you
06:07 - 06:10
connect to the battery. That is normal.
06:08 - 06:12
And that would have been the end of it.
06:10 - 06:16
So, we hooked this up. It's going to
06:12 - 06:16
spark. So, let's uh let's go for
06:16 - 06:21
it. Yep, that's a spark. It was not
06:28 - 06:31
uh key switch or what the manual calls
06:31 - 06:37
is open circuit. Throttle's connected.
06:40 - 06:44
nothing. Probably got these
06:49 - 06:57
backwards. All right. So, green goes to
06:52 - 06:57
gray. Yellow goes to black. Red to red.
07:02 - 07:06
nothing. Let's try the key
07:07 - 07:12
switch. Oh, sparked. I heard a click
07:15 - 07:23
motor. Uhoh. Let's
07:19 - 07:23
see. Oh, there it goes.
07:30 - 07:34
All right. Well, it works pretty pretty
07:32 - 07:36
much self-explanatory
07:34 - 07:38
there. Play around more of these
07:36 - 07:41
switches. It came with reversing. Let's
07:45 - 07:49
in. So, it goes one way. Hit
07:49 - 07:54
reverse. So, this is interesting. So you
07:53 - 07:57
switch directions at the gas pedal.
07:54 - 08:00
Nothing. At the gas pedal again, it
07:57 - 08:05
goes. So let's go whatever direction it
08:00 - 08:05
is now. Nothing. Gas pedal
08:05 - 08:12
goes. I don't know what that's
08:08 - 08:14
about. Whatever. Uh brakes three-speed.
08:12 - 08:16
So I have a little three-prongong
08:14 - 08:19
switch. Three wires. Let's see what
08:23 - 08:28
So that's full throttle. It's pretty
08:25 - 08:28
much where it was. Switch is in the
08:30 - 08:36
middle. All right. So that's
08:36 - 08:42
medium, and high. Okay. So you need the
08:40 - 08:45
switch to get high speed cuz without the
08:42 - 08:45
switch, I guess you're just on
08:47 - 08:55
medium. Yeah. So that's that's no switch
08:52 - 08:58
input. All right. So switch is required
08:55 - 08:58
for that if you want to go
09:01 - 09:05
fast. Indicator light. Let's see what
09:10 - 09:15
does. I don't know what kind of voltage
09:12 - 09:18
we're getting out of here. I think this
09:15 - 09:20
would use like a 5volt signal.
09:18 - 09:20
Let's find
09:25 - 09:30
out. All right, my arm's in the way, but
09:27 - 09:33
I think you can see 4.2 volts. So, the
09:33 - 09:39
light probably going to be 5
09:36 - 09:43
volts, four,
09:39 - 09:44
whatever. 52.9. So, that's battery
09:43 - 09:46
voltage. All right. All right. So, we're
09:44 - 09:49
not hooking up a normal 12vt light bulb
09:46 - 09:52
or a 4volt or whatever volt light
09:49 - 09:56
bulb. All right. I have an old electric
09:52 - 10:00
scooter with a uh 38 volt. I ripped it
09:56 - 10:04
apart cuz it broke, but it's got a
10:00 - 10:06
ball. Well, I had I just took it out,
10:06 - 10:10
black. I don't know what these wires do.
10:08 - 10:13
I don't care. I don't even know if Hey,
10:10 - 10:13
look at that.
10:14 - 10:20
All right. So, now we got an amber
10:22 - 10:26
illuminates. Let's turn the switch off.
10:24 - 10:29
All right. So, that's Yeah. All right.
10:26 - 10:29
That's cool. On on
10:35 - 10:39
light. Now, the next one is
10:39 - 10:44
brakes. I don't know what that does.
10:43 - 10:47
All right. Well, let's just might as
10:44 - 10:51
well experiment,
10:47 - 10:51
huh? Put the switch in
10:52 - 10:57
there. All right. So, we're going. We're
10:54 - 10:59
going. We're going. Ah, it breaks. Okay.
10:57 - 11:01
So, it stops the
10:59 - 11:04
motor. All right. So, that's not working
11:01 - 11:04
unless that's on.
11:17 - 11:23
Okay. If I full throttle and hit
11:23 - 11:27
reverse. Let's find
11:30 - 11:36
out. I'm guessing there's going to be
11:32 - 11:36
some kind of protection in here.
11:41 - 11:46
Okay. So, it shuts it off until I go to
11:50 - 11:55
pedal. All right. My concern with this
11:53 - 11:59
kit is the gear. It comes with a T8
11:55 - 12:03
gear, I think, which does not work with
11:59 - 12:04
what I want it for. I need a 40 chain.
12:04 - 12:12
um, there you say it has a half inch
12:07 - 12:13
diameter shaft with 6 inch shaft length.
12:12 - 12:15
And that's a problem because I wasn't
12:13 - 12:17
able to find the gear I needed. And I
12:15 - 12:19
don't don't believe that that's going to
12:17 - 12:21
have a/2 inch diameter shaft because
12:19 - 12:25
this thing is not made in the US.
12:21 - 12:28
Therefore, it's made using metric lathes
12:25 - 12:30
and mills and, you know, manufacturing
12:28 - 12:32
equipment. I mean, maybe it has a/ inch.
12:30 - 12:33
I don't buy it.
12:32 - 12:37
All right. So,
12:40 - 12:48
0.46. So, just shy of half an
12:43 - 12:48
inch, but realistically 12 mm
12:51 - 12:57
shaft. It's just shy of 12 mm. It's a 12
12:54 - 13:02
mm shaft, not a half inch. Close, but
12:57 - 13:04
definitely not a half inch. Uh, there
13:02 - 13:06
are companies that sell gears. I don't
13:04 - 13:08
know how I found these. I think I just
13:06 - 13:09
got lucky and stumbled across it. Uh,
13:09 - 13:17
thing. Oops. It is a 420 10 to gear.
13:14 - 13:19
Now, 420 and 40 gear chains, they the
13:17 - 13:22
same pitch. It's just the 40 chain is
13:19 - 13:25
much beefier and larger. So, the chain
13:22 - 13:28
will fit around a 420 gear, but it's not
13:25 - 13:29
going to work on a T8. So I what I
13:28 - 13:31
needed to know if that gear would fit
13:29 - 13:33
and there was no way to actually know
13:31 - 13:35
that unless I bought it and measured it
13:33 - 13:36
because again I didn't believe that was
13:36 - 13:41
shaft. I don't have this gear, but I'm
13:38 - 13:43
going to find
13:41 - 13:45
out. So this the wide spot of the gear.
13:43 - 13:50
Well, let me show you the gear that
13:45 - 13:50
comes with it. Spare profile here. Can't
13:50 - 13:55
see. Anyway, it's a kind of a
14:01 - 14:06
There you go. It's not round. It's kind
14:03 - 14:06
of a D-shaper. It's got two
14:08 - 14:12
flats. All right. So, according to my
14:10 - 14:15
instructions, which I printed out, the
14:12 - 14:17
widest point is 10 mm. The narrow point
14:17 - 14:27
mm. So, we are
14:20 - 14:28
at 10.03 03 10.5 10.05. So yeah, that's
14:27 - 14:30
10 millimeters if I've ever seen it. And
14:28 - 14:33
then the narrow side of it is going to
14:30 - 14:38
be 8.5 on the gear we can buy. And this
14:33 - 14:40
is 8.55 8.56 depending on how hard I
14:38 - 14:44
push. So it's it's
14:40 - 14:48
8.5. So I can get the correct gear I
14:44 - 14:51
want to fit on that motor.
14:48 - 14:54
So, with a little bit of work and
14:51 - 14:56
understanding, rewiring of the throttle,
14:54 - 14:58
the kit works. Motor spins. I understand
14:56 - 15:00
how it works now. And I know I can
14:58 - 15:01
change out that gear for something that
15:00 - 15:05
isn't a metric gear
15:01 - 15:09
size. All in all, not
15:05 - 15:11
bad. Aside from the initial plug it in
15:09 - 15:14
spark, you get a pretty straightforward
15:11 - 15:17
kit. Works fine. works as
15:14 - 15:19
advertised except for the shaft which
15:17 - 15:21
luckily doesn't work as advertised
15:19 - 15:23
because that means I can put any type of
15:21 - 15:27
gear I can I want on there
15:23 - 15:29
really. So that is a good
15:27 - 15:32
thing. As far as this battery charger
15:29 - 15:34
it's 98 volt 12 amp hour output 59
15:32 - 15:36
volts. Now that battery is only half
15:34 - 15:37
capacity probably a little less because
15:36 - 15:39
it's been in storage for months and
15:37 - 15:42
months and months. Uh it's possible it
15:39 - 15:44
should be 59 volts but I doubt it. I I
15:42 - 15:46
wish that Vaver said what kind of
15:44 - 15:48
charger this was. So, I don't need this
15:46 - 15:51
and I don't need
15:48 - 15:53
this, you know. So, it's just useless
15:51 - 15:55
stuff they threw in the kit that I I
15:53 - 15:57
going to throw away. I I really wish
15:55 - 16:00
they didn't send that into the kit
15:57 - 16:02
because it's just a waste at this point.
16:00 - 16:05
So, take this information, do with it
16:02 - 16:08
what you will. Questions, let me know.
16:05 - 16:11
Otherwise, seems like a fine kit so far.
16:08 - 16:11
See you later.
