0:04
this time on imperatus we make some
0:07
major upgrades to our lithium system by
0:09
fitting a victron B2B charger the Orion
0:13
type isolated
0:15
and a simple sketch and an idea turns
0:18
into something well a little bit more
0:21
complicated and of course a lot more
0:24
work but it's absolutely totally worth
0:27
it when you see what it is we've done
0:31
make sure you watch to the end
0:33
[Music]
0:45
[Music]
0:49
oh welcome back aboard impetus
0:53
we're on the electricals again
0:56
um you know that we changed to lithium
1:00
earlier this year just before I managed
1:03
to get myself slightly ill
1:06
um and we've been gently cruising around
1:08
Turkey uh trying out our lithium we've
1:12
been cooking by Electric by Electric hob
1:14
boiling our water in an electric kettle
1:17
heating our shower and uh hot water from
1:21
uh uh clarifier by electric and we've
1:26
been charging via the Sun
1:28
as we've moved around obviously our
1:30
batteries have been charged by our
1:32
alternator via one of these which is a
1:36
DC to DC charger this one's isolated and
1:39
it's from victron we're not sponsored by
1:42
a victron we just find their gear is
1:44
really good and it does what it says on
1:46
the box
1:47
we are going to fit a second one of
1:50
these in parallel but we're going to do
1:52
something a bit different well
1:55
my good friend Dean from TZ was back in
1:58
the UK and while he was back in the UK I
2:01
uh I managed to get him to fold up some
2:03
uh aluminum or aluminum angles
2:07
these angles will fit directly
2:10
underneath the battery to battery
2:12
charger and of course we've already got
2:15
one of these so I will need a second one
2:19
for the new one that we're going to fit
2:21
what we're also going to do is I bought
2:24
two of these computer front fans and
2:28
these are the high output they move a
2:30
lot of their type fans
2:33
um they are 12 volt and I think they're
2:37
0.03 of an amp hardly anything but I'll
2:40
put some uh put some details in the
2:43
description
2:44
today I'm going to mount on the bottom
2:46
of there and I'm going to cut a big hole
2:49
in here
2:50
so that the air is pushed up
2:53
through the cooling
2:55
veins on here and out and keeps those
2:59
cold
3:00
now even though there are only
3:04
0.03 of an amp or whatever it is what
3:07
I'm going to do is I'm going to control
3:09
those
3:10
two fans
3:13
with these
3:16
these are
3:18
thermostatic switches
3:20
I'll put one up there and zoom in so
3:23
that you can see it so this is the
3:25
thermostatic switch it is normally open
3:28
the contacts from one side to the other
3:31
aren't touching until that switch gets
3:34
to 40 degrees Celsius
3:37
40 degrees Celsius
3:40
the little switch inside closes and
3:43
these will then switch up to 20 amps
3:46
those that switch will then switch on
3:51
these fans now I've got two of those and
3:54
the reason I've got two of those is I'm
3:57
going to feed these switches put these
4:01
switches in parallel so that if either
4:03
one of those switches fails both the
4:06
fans will still come on when the
4:09
Chargers reach 40 degrees Celsius
4:13
so there's a couple of other upgrades
4:15
I'm going to do while I'm doing that
4:18
the first upgrade is I've managed to get
4:21
my hand on some victron ANL 60m fuses
4:26
and the cable that we're using needs to
4:30
be protected
4:31
I've only got uh inline fuses at the
4:35
moment I'm not very happy with them I
4:36
wanted proper uh fuses as the ANL type
4:40
because they're very useful
4:42
and they're
4:44
they're just more robust in my opinion
4:47
um so I have two of those
4:50
one for each of the
4:52
batteries and battery chargers and
4:54
they're rated at 60 amps because that's
4:58
what victron suggests that you need
5:00
between the batteries the battery
5:03
charger and your lithium that makes
5:06
sense for the size of cable that we've
5:08
got
5:08
so I've drawn up a circuit diagram for
5:11
you
5:12
we might put it on the uh on the website
5:15
so that you can have a look but uh
5:18
and so that you can download it
5:19
yourselves rather but if uh just freeze
5:22
the video for a moment when the circuit
5:25
diagram comes up and you'll see exactly
5:27
what it what it is you're doing
5:30
well I've finished marking out these uh
5:34
angle the first one
5:36
I've scribed all the relevant positions
5:39
on the underside
5:43
of the angle the reason I've done it on
5:45
the underside is because the underside
5:48
is smaller than the top side and I want
5:53
to make sure that the holes have got
5:54
clearance
5:55
rather than ending up drilling through
5:58
that radius because that radius is
6:00
formed
6:01
when the brake press comes down and
6:05
performs that that angle so the
6:07
underside is where I've marked that out
6:11
you can see
6:13
that I've marked for the position of the
6:16
battery to battery charger which is
6:18
there there and there I've measured out
6:22
and scribed out for the position of the
6:25
thermostatic switch which is this one
6:28
here all marked out and
6:31
102 millimeter hole right in the center
6:34
of which I've marked the center point
6:37
for my big hole cutter to cut through
6:40
now before I actually
6:43
um get started on the big hole what I
6:45
will do is I will draw
6:48
two of these holes hold and clamp the
6:51
second
6:52
angle underneath
6:55
like so
6:57
with
6:58
um
6:59
two more grips
7:01
and I will then drill all the rest of
7:04
the holes
7:05
using the top marked out surface as a
7:09
template
7:10
knowing that it's in exactly the right
7:13
place
7:14
and that saves me having to do all that
7:16
marking out twice and of course the more
7:19
marking out you do the more likely that
7:21
you could make a small error so we will
7:24
have two which will be exactly right
7:26
I've checked all the positions on those
7:28
checked all the measurements and they're
7:30
perfect
7:31
no it was near perfect as I can get
7:35
and therefore we are ready now to go and
7:37
drill those out
7:52
to
7:54
[Applause]
8:01
the
8:04
foreign
8:08
[Applause]
8:17
[Music]
8:23
[Music]
8:38
foreign
8:47
how many kilowatts is this drill
8:50
this is a tiny DIY thing to be honest
8:56
um but
9:00
it's too easy to bring on the boat
9:04
slipping in that Chuck again
9:06
yeah but it's two-thirds of the way
9:09
around here nearly there
9:12
it's not the ideal well that's what
9:14
we've got in it yeah
9:25
watch it cutting and then slight going
9:29
down and slashing through your foot all
9:30
right
9:34
because it comes off
9:35
[Applause]
9:42
that's it good job
9:45
uh I wouldn't pick them up they'll be
9:48
red hot four men looking down old they
9:50
are there's a hole brilliant
9:53
you're going to ask me and why is it
9:57
whenever you do any filing none of the
10:00
aluminum or aluminum ever sticks to your
10:02
foil
10:04
yeah and I'm gonna say that's easy David
10:07
I just take some chalk
10:10
from my kiddies chalkboard and put it on
10:13
the file
10:14
and that stops all the aluminum
10:16
sorry aluminum from sticking to the foil
10:22
another top tip
10:27
Apprentice to spend hours and hours and
10:29
hours with a file card cleaning all your
10:31
files up for it
10:41
with all the holes drilled and bursts
10:43
removed by either chamfering or filing
10:46
it's then time to fit the thing together
10:48
this was fairly easy as I had most of
10:52
the nuts and bolts that I needed on
10:54
board but I did have to go and buy five
10:57
M4 nuts Nylock and one long series Alum
11:02
bolt in M4 I believe it was once it was
11:06
all marked and put together it was then
11:08
time to put the switches in and make
11:11
sure that the face of those contacted
11:13
the black aluminum fins
11:17
we've got to take this battery to
11:21
battery charger out and mount it on the
11:23
brackets
11:24
to make the pair up
11:27
so I have turned off the battery to
11:30
battery via the Bluetooth I've turned
11:34
off our inverter
11:35
I'm going to disconnect the battery feed
11:40
which is that one there and I'm going to
11:42
disconnect it from the lithium so
11:44
everything is turned off at the moment
11:47
um
11:49
I'll pull the Pug on it and then I'll
11:51
disconnect that's a very smart new
11:54
spanner roll you've got there yeah I
11:56
don't know where it came from it just
11:59
it just I do like to have everything in
12:01
a place and a place for everything that
12:03
just suddenly appeared I don't know
12:06
where it came from
12:10
um so
12:11
feed
12:13
for the battery to battery charger first
12:16
we're going to take the
12:20
a little green pin out so that turns it
12:24
off
12:25
it's already off on the Bluetooth but
12:28
that actually turns it off
12:31
carefully going to remove
12:35
this positive
12:40
that's that one off
12:42
[Applause]
12:46
so I've taken the other battery to
12:48
battery
12:50
charger out down there
12:53
and that is now mounted on its plate
12:56
with its fan and it's a thermostatic
12:59
switch
13:00
number two is here and it's temporarily
13:04
connected to the lithium
13:06
and I've put the small dongle in the
13:08
little green dongle there
13:10
to fire it up because on this one it's
13:14
Bluetooth controlled and I'll probably
13:16
need to update the software
13:19
and I want to rename it and I'll rename
13:22
it b2b2
13:25
and that one's b2b1
13:28
now let's get my phone
13:30
and
13:32
let's do that oh 4 000 messages right
13:36
let's get rid of them first
13:38
put iPhone on and it's showing up here
13:42
so I will
13:44
connect it up
13:47
pairing is five zeros I think it is
13:51
one two three four five maybe six
13:57
[Applause]
14:01
oh and surprise surprise we need an
14:04
update
14:06
so we're on current version
14:10
that was 1.03 I think
14:13
and the new version is 1.1 it's
14:15
uploading
14:23
somewhere
14:24
is updated and I'm now just going to
14:27
rename that
14:30
power supply mode no we want it as
14:36
not now I don't want to change the PIN
14:39
code now we want to change it to charger
14:43
and battery settings
14:45
Factory smart lithium that's what we
14:49
want
14:49
which is the default one
14:52
so then we go back
14:56
and we go back again and we go there hit
15:01
that again
15:02
product info and we want to edit the
15:07
name
15:08
so we get rid of that and we want B
15:13
and then two
15:15
and then
15:18
B2B
15:24
2
15:28
okay and then come back
15:31
back back
15:33
he's off at the moment
15:38
that's perfect
15:41
there and now I can take the little
15:43
green dongle out of the back disconnect
15:46
it and then do all of the wiring once
15:49
I've decided exactly where these are
15:51
going to go that's going to be a mission
15:53
on its own
15:54
let's get on with that
15:56
three weeks later
16:00
oh that's it all done now the uh
16:04
observant among you will notice that
16:07
I've changed these for 10 mil cables
16:09
when I installed the original single B2B
16:12
I used six millimeter cable and that's
16:15
because the Run of cable was very short
16:17
less than 500 millimeters
16:20
with this design I'm running a lot
16:22
longer cables over a meter and therefore
16:25
it was necessary to go up to 10
16:27
millimeter cable except on the two
16:30
outputs which were very short I'll
16:32
explain
16:35
um I couldn't get any black and I
16:37
couldn't get any black tape and I
16:39
couldn't get any long lengths of um heat
16:42
shrink this is the basic circuit diagram
16:45
from victron and as you can see
16:47
obviously done in red and black I
16:49
couldn't get any black and so I had to
16:52
color code it with some tape and some
16:54
heat shrink I'll change that later but
16:57
for now it's red and black ish
17:00
okay here's the drawing for our setup as
17:03
you can see those two heat sensitive
17:05
switches thermostatic switches are in
17:08
parallel to the two fans if either one
17:11
of those closes
17:13
then both of the fans will come on
17:15
that's the way we've rigged it I haven't
17:17
put the override switch in yet again
17:19
that's something I'll do unfortunately
17:22
well fortunately we're on the move and
17:25
uh we just have to make do with what
17:27
we've got what we can get hold of while
17:29
we're sailing that's my excuse and I'm
17:32
sticking to it that's basically all done
17:34
we're now charging at 60 amps you can
17:37
hear I've got the engine running in the
17:39
background tidied this up a little bit
17:41
gotta run the Hoover through
17:42
everything's clipped and cabled
17:45
this is um the temperature
17:51
um
17:52
sensor for the battery and why they make
17:56
it so big why because I'm never going to
17:58
get a cover over that
18:01
I'll have to have a look and see what I
18:02
can do with that but otherwise yet all
18:05
done
18:05
tidied up a little bit
18:08
maybe I should put a clip there
18:11
yep but that's it done and dusted
18:15
um the battery is moved into this one
18:18
next to me
18:19
and clip down
18:21
I like to put a new base in for that
18:24
um
18:26
decided that rather than run that extra
18:29
cabling up to the terminal so I'd run
18:32
that battery in that other box and let
18:35
these run now I'm waffling away
18:39
um I know that they do work
18:42
these charges are just warming up now
18:45
not not that much
18:47
but just warming up
18:50
um these two bits of cable are six mil
18:52
they're very short run so I only need to
18:55
run them in six mil the rest I need
18:57
their
18:59
got to be running 10 mil so
19:02
that's because of the length of them and
19:05
the fact that the input side
19:07
takes a lot more current than or
19:10
considerable amount more than the output
19:13
current and that's because the
19:14
inefficiency of these as it Alters one
19:17
voltage to another voltage or a high
19:20
amperage
19:22
so yeah I needed to run 10 mil
19:26
feeds in and then that little short bits
19:29
I can run in six mil maybe I'll change
19:32
that to 10 mil later J just to make it
19:35
look nice and even but it's Aesthetics
19:37
not to
19:39
not necessary
19:41
so
19:43
I was hoping to be able to show you
19:45
these warming up but I can't see what
19:48
there
19:51
38 on the veins
19:55
so just to prove that the uh the fans
19:58
are working
20:02
he's a
20:06
he's working
20:08
air is coming up
20:10
from there
20:13
temperature
20:16
let's have a look
20:19
temperature there
20:21
36 41.
20:24
41 degrees Celsius look
20:27
both fans on both working
20:30
both blowing air up and feel that coming
20:32
through
20:39
that is bloody perfect
20:43
a couple of screenshots from my iPhone
20:45
then impoverished speed to be one and B
20:48
to B2
20:50
all plugged in working and showing up on
20:53
the iPhone not much you can control from
20:56
there but at least you can see they're
20:58
on
20:59
so another screenshot from my iPhone 54
21:04
amps look we're charging not quite 60
21:06
and that's because the other six amps
21:08
are used for the fridge and freezer
21:12
and on this shot you can see that our
21:14
starter battery is at 14.19 volts and
21:19
the voltage on the lithium is 13.47
21:24
and this next shot is from our victron
21:27
website where we can monitor stuff away
21:30
from the boat you'll see that we're at
21:32
95 percent there
21:34
and we're putting 749 watts in even
21:38
though it does say minus here's another
21:40
screenshot
21:42
and finally just a track of the day's uh
21:47
Power that's quite useful to see that
21:49
we're putting a lot in right at the end
21:51
of the day
21:56
the mouse screw
22:00
down in
22:02
ah right so that's them two in air gets
22:08
sucked sorry blown out of there that's
22:12
the vent that goes up behind there and
22:14
behind the TV comes out the vent at the
22:16
top there we haven't drilled any holes
22:18
in this bulkhead and there's a really
22:20
good reason for that this bulkhead
22:24
sorry this bulkhead that bulkhead this
22:27
bulkhead and that bulkhead are all
22:30
watertight
22:31
other than
22:33
the limber hole one limber hole at the
22:35
bottom there the idea of that is if the
22:38
boat gets hold in any one of these
22:39
positions the water will only come up as
22:43
far as the water outside and the water
22:45
level outside is about where those
22:46
batteries are
22:48
so this will remain intact and you won't
22:52
sink the water will only go out of here
22:55
as quick as it goes out the limber hole
22:58
which is smaller than the
23:00
bilge pump that we've got having said
23:03
that I did change the bilge pump for a
23:06
huge one so
23:07
but that's all the bavarias built like
23:09
that all of these
23:12
sides
23:14
um you know settees
23:16
the bed at the front there
23:18
we've all got um crashed bulkheads in
23:21
and they're all high
23:23
and the reason for that is because they
23:25
need to be higher than the water is
23:26
outside not a lot of people know that
23:28
but it's part of their safety design I
23:31
think it's a good idea
23:33

I want to say really I hope to say
23:49
really I'm not allowed to lift anything
23:51
because I'm still
23:53
um recuperating from this
23:55
so I'm not allowed to lift anything I
23:57
have to be careful and lift things with
23:59
both
24:00
both arms but I am getting my strength
24:02
back but they're worried about me
24:04
pulling my chest apart so

24:08
