00:00 - 00:03
Ur while on Brandon's
00:04 - 00:10
garage that's that's pretty ugly a lot
00:08 - 00:13
of corrosion going on a lot of these
00:10 - 00:17
battery posts it's really not not good
00:13 - 00:20
looking and now for the stunning
00:17 - 00:24
conclusion all right these are the
00:20 - 00:27
enjoybot 12vt lithium 100 amp hour
00:24 - 00:28
batteries I picked up for my 36 volt
00:28 - 00:33
cart uh I meant to put these in the golf
00:31 - 00:35
cart right away the thing is the golf
00:33 - 00:38
cart works and I don't have a charger
00:35 - 00:40
for a 36volt battery bank yet so I
00:38 - 00:42
didn't get around to it the batteries
00:40 - 00:44
and the golf cart they
00:42 - 00:46
got well it's not the batteries
00:44 - 00:47
batteries are okay it's the cables that
00:46 - 00:49
just have no life left in them and I
00:47 - 00:51
don't feel like replacing the cables
00:49 - 00:54
again when I got these three Beauties
00:51 - 00:57
sitting here so it's time to put these
00:54 - 00:59
into the golf cart these two are charged
00:57 - 01:01
and ready to go I've been using them for
00:59 - 01:03
my trolling mode Motors this one has
01:01 - 01:06
been sitting in the box so I got to get
01:03 - 01:08
that one charged got so I got to charge
01:06 - 01:10
this up and then I got to connect them
01:08 - 01:12
in parallel for a little while let them
01:10 - 01:14
balance each other out and then we can
01:14 - 01:20
started this is my vver DC clamp meter
01:17 - 01:24
it'll tell you the DC amp something he's
01:20 - 01:26
using so you can clamp it over a wire
01:24 - 01:29
and it'll tell you how much amperage is
01:26 - 01:30
drawing or being drawn through that wire
01:30 - 01:33
when I was shopping for one of these it
01:32 - 01:35
turns out it's pretty hard to find one
01:33 - 01:38
that'll do DC and they're quite
01:35 - 01:41
expensive when they do vver one looked
01:38 - 01:44
like it'll do what I need to do so these
01:41 - 01:47
batteries I believe they say on them
01:44 - 01:50
actually all right it says standard
01:47 - 01:53
discharge current 20 amps so it can
01:50 - 01:55
handle 20 20 amps of discharge no issue
01:53 - 01:59
then it says Max continuous discharge
01:55 - 02:00
current 100 amps and my golf cart being
01:59 - 02:02
quite old and and who knows what
02:00 - 02:05
condition I don't know how many amps
02:02 - 02:07
that thing actually draws so I want to
02:05 - 02:10
find out that'll also tell us the range
02:07 - 02:13
that we can go with these things when we
02:10 - 02:15
find out the average amp draw so that's
02:13 - 02:19
why I picked this up to figure that out
02:15 - 02:21
but anyway so we'll try this out after
02:19 - 02:23
we get the batteries ready to go and see
02:21 - 02:26
where this project takes
02:23 - 02:30
us well I guess it's
02:26 - 02:33
charging so according to enjoy box here
02:30 - 02:35
we're supposed to colle connect them in
02:33 - 02:37
parallel like this for 24hour well the
02:35 - 02:40
battery I thought it was 24 hours on the
02:37 - 02:43
website but the battery says at least 12
02:40 - 02:46
it's been like 30 hours or so um the
02:43 - 02:48
reason you do this is to let all the
02:46 - 02:50
batteries balance each other so they're
02:48 - 02:53
all going to be the same in equal
02:50 - 02:55
voltage so that's done and now they're
02:53 - 02:58
ready to be disconnected and hooked up
02:55 - 03:01
in series to get our desired 36
02:58 - 03:04
volts all right got it hooked up to the
03:01 - 03:07
primary battery cable coming off the no
03:04 - 03:11
battery I'm going to drive see what kind
03:07 - 03:11
of amps is called cart
03:13 - 03:17
323 you know that ain't bad 26 once we
03:17 - 03:24
moving a little better than I figured
03:24 - 03:28
actually and once we start moving it's
03:26 - 03:31
only drawing like 30
03:35 - 03:40
all right let me load up this pipe I
03:40 - 03:48
39 we're moving we go to
03:43 - 03:50
28 so over here this is soft sand
03:53 - 03:58
57 all right well that's still not bad
03:55 - 04:00
that's still fine we're going to do some
03:58 - 04:04
hill climbing here
04:06 - 04:10
37 all right well that tells me what I
04:08 - 04:12
want to know all right it's it's pretty
04:10 - 04:14
windy but I basically want to do a test
04:12 - 04:17
real quick to see how fast this thing
04:14 - 04:18
goes uh this results are a little skewed
04:17 - 04:21
cuz the batteries are a little old but
04:18 - 04:23
they're they're charged so yeah we'll
04:21 - 04:26
see how fast we go and we'll do a
04:23 - 04:26
comparison with the
05:17 - 05:21
all right well that gives us a decent
05:18 - 05:23
idea I suppose all right I put this LED
05:21 - 05:25
strip light suspended above the golf
05:23 - 05:27
cart roof with some bailing wire to
05:25 - 05:30
light the project up for us all right
05:27 - 05:32
some things you should know
05:30 - 05:32
if you're not
05:32 - 05:38
familiar when you charge up these lead
05:35 - 05:41
acid batteries they
05:38 - 05:42
release hydrogen might be nitrogen
05:41 - 05:47
pretty sure it's hydrogen I don't know
05:42 - 05:49
I'm no battery chemist um that is a that
05:47 - 05:52
is attracted to the lead on the battery
05:49 - 05:55
terminal and then we create a very
05:52 - 05:58
corrosive environment this
05:55 - 06:00
battery has usually been the worst it
05:58 - 06:02
died after I put put in my lights and my
06:00 - 06:04
fans and my screen and all the other
06:02 - 06:06
stuff in this golf cart and I needed to
06:04 - 06:09
replace it but you can get an idea of
06:06 - 06:11
how the other ones look there and
06:09 - 06:13
especially over on that side because I
06:11 - 06:15
haven't cleaned those up in I don't know
06:13 - 06:19
five months 6
06:15 - 06:20
months and it's common if you notice we
06:20 - 06:25
different connector right there that's
06:23 - 06:26
because that battery post you're not
06:25 - 06:28
getting a bolt on it anymore it's just
06:26 - 06:31
too corroded so I had to go over to that
06:28 - 06:33
thing to fix when that cable broke so
06:31 - 06:35
basically what I'm saying cables break
06:33 - 06:38
all the time on this golf
06:35 - 06:43
cart I mean I charge it most of the time
06:38 - 06:47
every day so yeah it sees a lot of use
06:43 - 06:48
and the corrosion really really shows
06:47 - 06:51
there is a lot of benefits to the
06:48 - 06:53
lithium uh for me the main is not having
06:51 - 06:55
to replace these battery cables when
06:53 - 06:58
everyone breaks whenever I try to do
06:55 - 07:01
truck stuff in my golf cart with
07:01 - 07:05
also the batteries are going to weigh
07:03 - 07:07
less these there's a lot of weight and
07:05 - 07:10
batteries in here those three are going
07:07 - 07:12
to put out you know more amp hours than
07:10 - 07:13
these I I believe but the batteries they
07:12 - 07:18
weigh less they go
07:13 - 07:20
further and last longer as in life
07:18 - 07:22
especially since we don't have at least
07:20 - 07:24
we shouldn't have the corrosion like
07:25 - 07:31
have uh so yeah basically I'm just going
07:27 - 07:31
to take off all these wires
07:33 - 07:37
is there even a bolt on this
07:35 - 07:41
battery I said bolt but obviously I
07:37 - 07:44
meant not look at that thing what's
07:41 - 07:48
there whatever was there is
07:44 - 07:48
gone some vice grips to get that thing
07:55 - 07:59
well I think they're all
07:58 - 08:02
disconnected
07:59 - 08:06
this is the charger this is
08:02 - 08:06
the main cable that goes to our
08:09 - 08:13
and couple more cables in here that's
08:14 - 08:20
go when you buy these batteries at
08:17 - 08:23
Walmart sometimes not Walmart Sam's Club
08:20 - 08:24
we don't have a price Club around us oh
08:23 - 08:28
we got a Sam's
08:24 - 08:30
Club anyway at Walmart they didn't give
08:28 - 08:32
me these when you buy them at Sams they
08:30 - 08:36
offer them one so I took
08:32 - 08:40
it they used to use a
08:36 - 08:40
strap this is much
08:43 - 08:49
easier all right cut you on a top
08:46 - 08:51
view CU there is no way I'm fitting
08:49 - 08:53
those three batteries into this golf
08:51 - 08:56
cart with its current layout batteries
08:53 - 08:59
are well they look like a standard car
08:56 - 09:02
battery size and the 6vt batteries are
08:59 - 09:05
just Just A Pinch smaller
09:02 - 09:06
so I've made the executive decision to
09:06 - 09:11
this resistor
09:08 - 09:14
box so the three batteries can sit right
09:33 - 09:37
So the plan is to weld that bracket
09:34 - 09:39
there weld this one here rotate it
09:37 - 09:41
sideways and then bolt it down to these
09:39 - 09:44
new brackets all right I've cleaned up
09:41 - 09:44
the area where I plan on
10:01 - 10:08
now this thing for un
10:05 - 10:13
familiar resistor
10:08 - 10:16
pack uh they are supposed to be cooled
10:13 - 10:19
kind of meaning they need airf
10:16 - 10:21
flow so you're not supposed to just I
10:19 - 10:24
mean you're supposed to give them air
10:21 - 10:27
flow which you know I'm going to
10:24 - 10:28
do but I couldn't mount it you know up
10:27 - 10:30
high and out of the way it's got to be
10:28 - 10:32
somewhere it's going to see flow from
10:30 - 10:35
the bottom any that's where that's
10:32 - 10:37
going so I'll get my Sharpie and I'm
10:35 - 10:40
marck out some holes get back out drill
10:37 - 10:40
some holes and mount it back
11:11 - 11:16
probably has to weld on one side of this
11:13 - 11:19
bracket I Just Whipped up and then uh
11:21 - 11:27
other that bracket is quite strong
11:25 - 11:30
that's a good weld
11:27 - 11:32
there all right
11:30 - 11:34
hooked that up correctly this time I
11:32 - 11:36
think I had it backwards first is on
11:34 - 11:37
this side that might have been right I
11:36 - 11:40
don't know but anyway so it's it's
11:37 - 11:44
hooked up I had to extend this this is
11:40 - 11:46
the cable that GS the motor that used to
11:44 - 11:49
be red I needed it longer I don't have a
11:46 - 11:54
red one that long so but I had black so
11:49 - 11:57
it went black uh it's annoying yeah but
11:54 - 11:58
it doesn't matter the uh originally at
11:57 - 12:00
least when I got this thing it had all
11:58 - 12:04
red wires in it well actually they all
12:00 - 12:06
look like this so who knows but anyway
12:04 - 12:09
so it should be hooked up and ready to
12:06 - 12:11
go now so the plan is just start putting
12:09 - 12:15
batteries in
12:11 - 12:19
it this is the negative so I'm going to
12:15 - 12:19
put the first one right
12:21 - 12:25
here just like
12:25 - 12:31
negative fit nicely just like that then
12:29 - 12:31
I'll make all the other ones
12:35 - 12:41
match those things look great in there I
12:37 - 12:43
think so much better than what was in
12:41 - 12:44
there previously even when they were new
12:43 - 12:47
they didn't look
12:44 - 12:50
good I don't know that just looks nice
12:47 - 12:55
to me o will this reach
12:50 - 12:57
no I want them going all the same
12:55 - 12:59
direction guess I can make a longer one
12:59 - 13:05
yeah might as
13:01 - 13:07
well all right cuz see by going the same
13:05 - 13:10
direction this has to go to here this
13:07 - 13:13
has to go to here these two cables are
13:10 - 13:17
exactly the same length but by flipping
13:13 - 13:20
them one's going to go sideways and the
13:17 - 13:21
next one's going to
13:20 - 13:24
loop I don't
13:21 - 13:27
know let's see what it looks
13:24 - 13:29
like I don't know that looks kind of
13:27 - 13:33
dumb although not really cuz you got
13:29 - 13:33
positive and negative right
13:33 - 13:38
there yeah I'll do that why not the
13:36 - 13:41
advantage with doing it that way is
13:38 - 13:43
nothing has to cross over the battery
13:41 - 13:45
everything can just come up and connect
13:43 - 13:47
to there so yeah a
13:47 - 13:51
backwards that's all
14:00 - 14:03
look at those
14:01 - 14:05
Beauties yeah they're worth more than
14:03 - 14:08
the golf cart but that's all
14:05 - 14:09
right the uh well we'll talk about it
14:08 - 14:12
tomorrow but I want to take this thing
14:09 - 14:13
for a test ride um I bundled up all of
14:13 - 14:17
wires H those are going to have to wait
14:15 - 14:19
I want to see what this thing can do
14:17 - 14:21
didn't mess with any wires well I mess
14:19 - 14:23
with all the wires
14:21 - 14:27
but they all went back the way they're
14:23 - 14:27
supposed to go so in theory this should
14:27 - 14:34
work it throws your head back it's so
14:31 - 14:34
quick all right well
14:37 - 14:43
let's this going this is nice this is
14:40 - 14:46
one hey little golf cart all right get
14:47 - 14:52
yeah put it in gear might
14:55 - 15:00
help I got pushed into the seat I know
14:58 - 15:02
isn't that neat
15:00 - 15:06
whoa what a difference you see how fast
15:02 - 15:10
it goes yeah all right well all
15:06 - 15:15
right you feel the front lift up
15:10 - 15:15
yeah yeah it's going pretty good
15:15 - 15:21
yeah so what do you think worth it yeah
15:18 - 15:22
for sure are you kidding see that thing
15:22 - 15:28
off oh where you going I don't want to
15:25 - 15:30
burn Rubber on the on the concrete glad
15:28 - 15:33
did it I can't wait you to do mine now
15:30 - 15:35
that's fine well I've been using the
15:33 - 15:38
golf cart for a little while and so far
15:35 - 15:40
so good you saw I took my dad on a ride
15:38 - 15:44
there and he seems to like it so much so
15:40 - 15:44
that now we're doing one in his golf
15:45 - 15:50
cart so the last piece of the puzzle for
15:48 - 15:52
this golf cart is this thing it's called
15:50 - 15:56
a buck converter but they might call
15:52 - 15:58
them some something else power converter
15:56 - 16:01
I don't know anyway this is going to
15:58 - 16:03
take our 36 volts is out of the
16:01 - 16:06
batteries of this and turn it into 12
16:03 - 16:08
volts that way we can run all my 12 volt
16:06 - 16:11
stuff mainly the
16:08 - 16:13
headlights um in a traditional golf cart
16:11 - 16:15
you would just tap into one of these
16:13 - 16:17
batteries and use that for your 12vt
16:15 - 16:19
signal with lithium you don't want to be
16:17 - 16:22
doing that you want all the batteries to
16:19 - 16:23
be at the same state of charge always so
16:22 - 16:26
you don't want to tap into one battery
16:23 - 16:28
to get 12 volts so you want to tap into
16:26 - 16:32
all three and use one of these to drop
16:28 - 16:33
your 36 volts down to 12 okay Buck
16:32 - 16:36
converter is
16:33 - 16:39
installed it uh these two wires run of
16:36 - 16:41
the headlights up front and these two
16:39 - 16:44
wires this one goes to ground and this
16:41 - 16:47
one runs to my headlight switch right
16:44 - 16:50
here which pairs over to the golf cart
16:47 - 16:53
on switch which connects over there
16:50 - 16:55
somehow now the old the old uh battery
16:53 - 16:57
gauge isn't really going to work with
16:55 - 16:59
the lithiums but I decided to leave it
16:57 - 17:01
on just say an indicator light when the
16:59 - 17:05
golf cart's on so I think that was a
17:01 - 17:07
good idea and then we should have
17:07 - 17:12
yay now this is interesting I cleaned up
17:10 - 17:15
the old batteries the plan is to sell
17:12 - 17:18
them and use the money to buy a charger
17:15 - 17:20
for the golf cart if that doesn't happen
17:18 - 17:22
I'll be using the charger I have to
17:20 - 17:24
charge each battery but chances are only
17:22 - 17:27
do that a couple of times before I pry
17:24 - 17:29
open the wallet and just buy one so I
17:27 - 17:33
noticed on here they do actually say 100
17:29 - 17:36
minutes at 75 amps see if I remember how
17:33 - 17:40
math works so 100
17:36 - 17:43
minutes over 75 amps
17:43 - 17:51
per minute over an hour 80 amp
17:48 - 17:53
hours yeah that's probably right now a
17:51 - 17:56
quick Google search so I don't know
17:53 - 17:58
where Google is buying their golf cart
17:56 - 18:01
batteries but I don't think I have 180
17:58 - 18:03
to 225 amp hours on those golf cart
18:01 - 18:05
batteries I may I just don't I just
18:03 - 18:07
don't think so because usually when I
18:05 - 18:10
drive to the grocery store and the
18:07 - 18:12
mailbox and stuff I can usually do that
18:10 - 18:14
I can go to the mailbox you know five
18:12 - 18:16
times grocery store that's two miles I
18:14 - 18:18
can do that about four times before the
18:16 - 18:20
battery indicator starts beeping at me
18:18 - 18:22
and you can feel the golf cart slowing
18:20 - 18:24
down and that's not with these you know
18:22 - 18:27
aged batteries that I have that was kind
18:24 - 18:29
of when it when it was newer the
18:27 - 18:31
batteries so I don't know I don't I
18:29 - 18:35
don't see it the 80 amp hour is that I
18:31 - 18:37
believe this I don't buy it so let's
18:35 - 18:40
leave the seat off making it fun to
18:37 - 18:43
drive and go uh do some more testing
18:40 - 18:45
shall we okay I rigged myself up a
18:43 - 18:48
temporary seat got the clamp meter on
18:45 - 18:51
there so let's give this a go it's
18:48 - 18:52
pretty windy outside still it's just
18:52 - 19:00
here all right taking off well that's
18:55 - 19:04
surprising 13 amps oh turn all right I'm
19:00 - 19:04
in the soft sand got to find a way
19:04 - 19:09
to get this clamp meter
19:07 - 19:12
better anyway that was surprising
19:09 - 19:14
leaving 13 amps that's seems pretty low
19:12 - 19:20
but we're in the soft
19:14 - 19:22
now 30 amps 25 amps 20 amps 19 amps all
19:20 - 19:25
right so that's uh that makes sense so I
19:22 - 19:28
think it is a little lower but that just
19:25 - 19:31
could be because we're hauling substanti
19:28 - 19:35
less weight let's go over here to the
19:31 - 19:37
uh way too soft
19:35 - 19:40
area tractor can't
19:37 - 19:43
go all right now let's see what this
19:50 - 19:59
yeah draw less amp so that's good climb
19:59 - 20:04
I'm going to switch over to the screen
20:01 - 20:06
recorder and we're going to do a uh top
20:04 - 20:08
speed comparison and also see how many
20:06 - 20:09
amps we're drawing at the same time
20:08 - 20:10
going to be better I'm going to go to
20:14 - 20:21
Road look like anybody's
20:29 - 20:32
all right we're still accelerating a
20:32 - 20:39
bit so we're at 13 amps now so I guess
20:36 - 20:40
we're at our top speed of 14
20:49 - 20:53
15 so we've dropped to 12.2
21:06 - 21:11
see we cross 16 oh we did
21:42 - 21:49
wow I basically did a big
21:45 - 21:52
loop I don't want to record here because
21:49 - 21:53
to get back well I can take the road
21:52 - 21:56
back that's
21:53 - 21:58
boring but anyway to get back I got a a
21:56 - 22:01
lot of starts and stops it's kind of
21:58 - 22:03
surprising how py this golf cart
22:01 - 22:07
is I know it's got a slightly higher
22:03 - 22:09
voltage than the uh lead acid batteries
22:07 - 22:13
do but I didn't think it would make a
22:09 - 22:13
noticeable difference like
22:14 - 22:19
this all right so we have 100 amp hour
22:17 - 22:22
batteries if we're drawing 15 amps an
22:19 - 22:26
hour that's you know 6.66
22:22 - 22:27
something times 15 miles hour 99 yeah
22:26 - 22:28
you're not I don't think you're going
22:28 - 22:33
maybe under ideal situations you can go
22:30 - 22:36
100 miles I mean I am pretty tempted to
22:33 - 22:39
go find a straight 100 mile long road
22:36 - 22:40
and see if it'll actually do it but I
22:39 - 22:43
don't really want to spend hours behind
22:40 - 22:44
the wheel of the golf cart either so to
22:43 - 22:46
truly know how far it goes you would
22:44 - 22:48
need to do like real world tests you
22:46 - 22:51
know starts stops varying road
22:48 - 22:53
conditions that kind of stuff but from
22:51 - 22:55
what it seem so far it's they're going
22:53 - 22:57
to they're going to go pretty far I'm I
22:55 - 22:58
don't think 30 mil is out of the
22:57 - 23:00
question I think think 30 mil probably
22:58 - 23:02
where it's going to be all right Gramps
23:00 - 23:04
wants to go rock hunting so I need to
23:02 - 23:07
finish this video
23:04 - 23:09
off so the batteries do cost a little
23:07 - 23:12
bit more than lead acid batteries unless
23:09 - 23:14
you factor in the fact that I've changed
23:12 - 23:16
two of those since I bought bought the
23:14 - 23:19
set two years ago then you're about the
23:16 - 23:21
same price the only difference is now
23:19 - 23:23
the cables aren't going to be corroding
23:21 - 23:25
away on them needing constant
23:23 - 23:28
maintenance and cleaning which I never
23:25 - 23:30
did anyway um fitting it in there
23:28 - 23:32
obviously I had to move that uh that
23:30 - 23:34
speed controller out of the way but that
23:32 - 23:36
wasn't really an issue and it's still
23:34 - 23:39
entirely reversible just need to knock
23:36 - 23:43
out the brackets I put in which is easy
23:39 - 23:45
enough to do in an attempt to earn some
23:43 - 23:47
commission money I will put a link below
23:45 - 23:49
to the batteries so if you're interested
23:47 - 23:52
have a look any questions let me know
23:49 - 23:55
I'll help you the best I can and see
23:52 - 23:55
y'all later
