Installing battery chargers in the trawler
Вставка
- Опубліковано 12 вер 2024
- In this video I install a couple of 240V battery chargers into the trawler to allow me to charge off the generator or shore power when it is available.
This a charger similar to the ones I used, but not the same brand www.amazon.com...

I think the more consistent but shorter (10-20min) videos is exactly what the algorithm wants as well as it being more convenient for you Stu. Comments also affect how the video does people, so don't be shy!
Really enjoy the new format of showing all the nitty gritty.
Thanks Robert.
Stu, you don’t want to mount the sea water strainer above the engine sea water pump. It will be difficult for the pump to suck up sea water in that position, and you will end up with overheating problems. Detroit diesels are very susceptible to damage from overheating.
Mount the strainer low in the bilge.
Second that every boat I've been on in Alaska and Washington that have strainers are mount as low as possible:)
Yes, I guess I might have to sacrifice ease of access for better normal operation. It certainly makes sense.
You might consider mounting it in the rear lazarette compartment for ease of access. It doesn't have to be mounted in the engine bay. I agree with keeping it at water level to reduce difficulty priming the cooling pump.
It looks like a pleasure to finally work in a suuuuper clean bilge area.. Nice work Stu!
It is much nicer to be down there now!
Great work man ! Give the puppy a pat for me . Oh , don't forget a few frosty cold ones when ya get home !
I will, and won't. ;)
Just wondering, how does someone give a thumbs down here? What’s to dislike? Excellent content! Thank you.
“Everything is upside down in Australia”? Best explanation I can think of.
Thanks mate!
I’ve been watching this since you got the boat, you’re resourceful, honest and persistent. Keep it up, maybe I’ll come down under to see the finished product. Never been there and it’s not very far from my retirement country.
Probably New Zealanders.
Down is the exact same good interaction as an up... What hurts is the VAST majority that doesn't click up OR down.
Awesome install Stu,those ban marie trays fitted just a treat and will last a long time.So happy for this mid week upload as it cuts down having to wait for much anticipated weekly uploads.
Thanks David!
Fresh single mullet fillets packed in salt wrapped firmly in a few newspaper sheets and freeze overnight remove sheets brush off salt repeat a couple times makes it a lot tougher it will stay on the hook better but be as fresh as day you bought it in both looks and smell keep it in a white foam box in a cool shady spot will last all day
keep up the awesome work stu love it and learning heaps cheers kev
We used to use a 'ballast box' (I think that's what it's called) to 'start' big industrial lights.Maybe an electrician could advise. Problems sound similar, they require big hit initially and then settle. Good luck, love your work.
Thanks mate, I'll look into that.
Great progress again, but one worry, you are going to attach the raw water hoses before fitting the engine because it's difficult to get to after. Having had a couple of incidents where it was necessary to close the seacock in an emergency, you may want to think of making a mechanism to attach to the side wall of the engine box for such an event. You just never know out at sea.
Loving the series. 🇮🇪
Given where it is positioned, it is very tempting to go to a remove controlled seacock of some description for sure.
Dangar Stu - The Jesus of lazarette
🤣
I wanted to click 50 likes to that one!!
The kitchen tubs were a great find. Thought though, mount foam rubber under the lips of them. The vibrations will wear out the metal and paint from where they sit.
Yes, definitely need to do something re the metal on metal thing.
Another great video Stu thanks for sharing it. The trawler is really coming along!
Good stuff Stu, coming together nicely mate👍🏴
Great idea the stainless trays for storage but definitely put some rubber or anti-vibration strips in. They will rattle and wear badly in a short time. Love your work mate. Cheers from Bribie Island QLD
Yeah, definitely need a raised rubber strip to both help lock them in and stop vibration.
You should have the wires facing downward on the chargers. So that moisture and water dont pool up and run down the wires into the unit.
I was going to say the same thing. He needs to install drip loops.
Second the recommendation with a service loop on the wire. At least 4" of wire running straight down before it makes a turn back up. Do what you can to keep moisture/condensation moving away from the electronicals.
ditto this
They are sealed units also ignition protected.
@@SkypowerwithKarl Karl Jensen Ip67 yeah, ~30min underwater. Those gaskets don't look too reassuring either. Having the wires facing down is just an extra precaution, making sure nothing gets in. But at the same time, giving condensation somewhere to get out.
I wanted to hang my charger sideways, instructions said "no".
Thanks again for taking us along!
Great information.
Love watching someone work.
Opening music,thats jazz,with fish.
Very jealous!!! You've got quite a nice set up going there. It's great seeing the boat moving with the swell.👍👍👍👍👍
Thanks mate. I can't wait to see the boat moving under it's own steam now.
very good vid Stu , having Eddie onboard makes it an excellent vid !!!!! keep up the good work
Thanks Matt!
Hey Stu, I haven’t had allot of experience with Plasma cutters, but I’ve seen many inverter welders (essentially the same machine)ruined on minesites due to being ran off a smaller generator. The general consensus from Boilermakers is that 8 Kva is the minimum size so as to not damage your machine and have smooth operation.
This article from weldclass essentially says the same thing - www.weldclass.com.au/blog/47-using-generators-to-power-inverter-welders-your-questions-answered
Hi Stu, like someone else said, the chargers would be better the other way up with the cables coming out the bottom to prevent water/damp ingress. You could then also use the slack cable below the chargers to form a cable drip loop. Looking good though, really like those chargers, neat idea 👍
Yes, given the screw holes will be the same I may well flip them over to be safe.
Your assistant, Eddie isn't much help! LOL! Anyhow, I'm really enjoying watching this old boat being transformed, excellent work Stu!! Also loved the videos of your trip to my home, the US. I wish I could've made the meet up in Hampton Virginia, I live 2 1/2hours drive from there. Maybe one day I'll get to go to Australia, one of the top 10 places I want to visit before I die. I met some good soldiers from your country years ago during the Gulf War when I was in the US Army. Good, tough soldiers. Met three here in the states as well while I was still serving back then, they were attending a US military school at Fort Benning in Georgia, all I can say about that is DAMN you guys can drink like a fish!! LMAO>
I hope you do get to visit Australia one day! :)
A peak-load capacitor will hold the start up draw for your plasma... matching and balancing the power demand will be easy for you. I like the multiple leads on the battery chargers... not being in parallel affords you a redundant system and the ability to monitor each battery independently is a bonus. Really enjoy the frequent posts!
It’s so sweet watching you cruising down the home straight whew that hull repair was so radical
It is getting close now!
In my experience, it doesn't take much to clutter your boat and when its cluttered, it makes it less attractive to jump on the next time.
Whenever ive done a clean up, its amazing how much it affects the way i feel about my boat, even though its my boats fault.
Clean boat, happy skipper.
Excellent vid Stu! Things are marching along nicely! :-)
Thanks Chris!
Things seem to be moving along -- a little here, a little there, a little fuzzy helper to help keep you on-task. Great update before I head off to work. Many thanks, Stu.
Getting there Randy, will be running soon!
gday from up cessnock stu great to see the ol girl making a come back bit by bit
Nice one Stu, I deffo agree with reducing the clutter, it makes life so much easier and of course it reduces the splash factor for falling overboard. Got to say, your wire runs are looking better than your mates but try to avoid coiling any of the runs, I found it turns them into an induction coil and even on 12v they can get pretty hot.
Thanks Mate. I too was wondering about coiling up the excess. I've been trying to find the definitive answer on how much of an issue that is and it seems that as well as the amount of current flowing, the geometry of the coil is also very important. Here, a lose oblong-shaped seems to be working in my favour en.wikipedia.org/wiki/Inductor
Probably too late now but set a table saw for 2/3 the sheet thickness then cut down each support line center the board will now fold down those lines allowing you to get it in and you can fold a side back over when you want to yet still act like a whole sheet when lying flat.
Liking the new format with more posts!
Fine job on those dual chargers. I really enjoy the updates on the boat. It’s gonna make you a super fine ride!!!!
One solution to reduce starting load is to wind a coil of say 30M of number 12 wire on a 5cm form as a starting point and see if it helps. Also, running power thru a long cord may also provide the sag needed for startup.
Interesting, I'll give it a try.
Hi Stu, Was just thinking when you fill your tanks with Diesel add some Biocide. This will stop any bacteria growth since they have been sitting for a while. You don’t want Black diesel and it happens fast , Cheers Mick
Yes, well worth doing.
C'mon man it's like midnight here...was just trying going to bed. Alright, I'll watch.)))
its like 2am for me XD insomnia is a bitch
You may want to mount the sea strainer so that the cleaning opening is just above the waterline. Much easier for the pump to prime.
Yeah, I think I might have to mount it a bit lower which is going to make it a pain to clean but it is more important that it works properly.
You may be surprised at how little you may need to access it. Unless you sail through a mat of vegetation, the only thing you will find in it are beads of styrofoam. If the strainer isn’t overwhelmed, most organic matter decays and turbulence grinds it down into such small pieces it passes through.
O great something to watch on my mid-watch ... cool mellow night for the ole Dangar Marine...
I really love that trawler. You’re doing a great job and things are coming together well. Thanks for bringing us along!
Thanks Jay!
Love the dig at us in the Northern Hemisphere Stu. As we fast approach Winter your fishing comment about the whispy cloud was really below the belt. As always I enjoy your vlogs.
I'll make it up to you with a free fishing trip if you fly south. :)
@@DangarMarine Haha. Ok...I forgive you. :-)
Stu try a couple of compressor run capacitors on the output that feeds the plasma cutter should help with the current draw on initial arc 😎
Those clouds look ominous best take cover
You can try using an inductive load on the generator when using the plasma cutter, a small 1hp motor running without a load should help, even a large grinder running.
I'll give it a shot!
I've had starting issues with equipment running on generators as well. I found the solution that worked for me was to tweek the governer screw to run a bit faster. This increases the voltage and gives troublesome gadgets some extra beans.
It's not a bad idea to put a volt metre on every now and then, because those screws can loosen off with vibration.
Of course, some electronic stuff can get the heeby jeebies if they're not fed the right diet.
Ken Godfrey was just about to say what you just said ken! Exactly the frequency will be changed by the extra speed of the generator and can cause far more damage if not careful than low voltage can. Also keep in mind those little brush style generators produce very dirty power it’s hard on eletronics and power tools anyway.
Of course I bow down to what is obviously far greater intellect. But I did point out that my suggestion was not without pitfalls.
Given that the output of this type of generator is dependent on constant revs, both the voltage and frequency are affected.
After discovering that my cure worked for me, I took the opportunity to test the output of a number of portable generators being used by my clients. Many of them were under performing.
Warren Neeves hahaha don’t worry about it just didn’t want you to blow anything up. But like you said you might actually just be bringing them up to where they need to be if they were underperforming.
Stu, if you put in a 15amp shore power inlet to feed those charges make sure you do it to the Australian standards there's one for boats as well as AS 3000 the wiring rules because it you ever want to use the boat commercially it will have to comply, also if the boat was to ever sink or catch fire while plugged in at the dock and the 240v installation is not to standard your insurance company will walk away. Also make sure you research galvanic isolators as well they go in the earth cable coming in from shore power to stop stray currents from eating your anodes then hull to quickly while plugged in, its worse here in Australia with our M.E.N system multiple earthed neutral system, it's basically path of least resistance and all that as salt water is a great conductor.
Yes, there does seem to be a lot to get right when it comes to connecting anything to shore power. I think I was given a galvanic isolator ages ago by a guy with a timber boat, I must dig it out and learn more about it!
Those are excellent “smart chargers”. The individual outputs are primarily for batteries smaller than 4Ds. They were primarily designed for charging multiple batteries that you would find in a trolling motor set up. Typically charging individual 12 batteries that are in series 24, 36 volts or 24 volts and one starting battery. To attempt to charge a 4D or 8D with a single lead will result with a battery that doesn’t reach a full charge or will take days because of the huge internal resistance of large batteries. If the instructions allow, perhaps you can parallel the leads to one battery. I highly recommend Vmax 8D AGMs. The minimum I charge them with 20 amps per battery and preferably 45 amps or 90 amps with two in parallel. Hitting batteries hard wakes up the chemistry and as long as it is not over charged they can last 8 to 10 years. Always with a smart (intelligent) charger or your killing your batteries. One last thing, when the batteries read 12 volts (with no load) it’s 100% depleted, stop and charge. If you charge when it’s only 75% depleted, you’ll get more cycles and life.
I like the way those Vmax 8D AGM batteries have the dual terminals too. They look very good!
Funny thing, a year later they seemed stronger. Stay away from the Chinese batteries, cheaper and you don’t even get what you paid for. Black plastic case with white writing, numerous brands from the same factory. I’ve replaced lots of these p.o.s’s
Some clouds... hahahahahahaha. Great post Stu.
I was scared! ;)
@@DangarMarine Too funny. Keep up the great work Stu, loads of people are enjoying your channel. Cheers Damo.
Good work, love watching the electrical work being done properly. I am learning so much and will apply it to my own Hawkesbury River cruisers. Keep up the good work Stu.
If you need someone to just stand and watch holding a bourbon telling you your doing it wrong. I'm your man.
The generator problem is most likely the electronics not liking the generator output. Plug a decent size motor into the generator at the same time and see if it helps. Sounds odd but there is science to it
I'll give it a try.
Most gen sets have idle up on them. But a plasma uses plasma air arc to cut so it may not be getting the initial amperage to start the plasma process. It also just may be it doesnt like the signal from genset so a inductive motor like a blender running b4 arcing may clean up the sign wave and work. Worth a shot. Oxy/acet may be a safer/easier bet on a boat. Obviously stored correctly not to make a bomb : )
I'll try adding an inductive motor, it's certainly worth a shot.
Hey, Stu, that's pretty clever putting a little gray frosting in the beard... makes you look more like a seasoned sailor! Let it grow a bit longer, then get a parrot and wear an eye patch, - they'll move out of your way. 😉
Eye patch is on order, should be here in a few days. ;)
Stu you mentioned about your cuter not having enough power from your generator to arc what you can do is put an ac capacitor across the plug for the cuter this doubles the voltage and makes the unit work easier. Just make share your unit can handle the voltage bump.
Cheers, Stu, another great video full of projects!
You might try running a ground wire from your genset,to anyplace convenient since it's a steel boat.I'm thinking the surge current when you fire up your plasma cutter may play into this as well. Just a thought.
I should look into that. I need to sit down and think about the various grounds on the boat.
This might help for fatigue in the plastic mounting boards. Have you thought about putting large washers on the head of the mounting bolt to spread the load of vibration fatigue in the plastic? Your idea is ok in a sailing boat. As soon as you have your engine running you have to think of the high-frequency vibration which is hard to prevent even with rubber dampers and shocks on the engine.
Yes, I was thinking the washers were in the same tray as the bolts but they weren't. I'll have to find them!
Essential items to be left on boat: 1970s banana chair, Cooper's x 6.
Nothing like a banana chair after a long dive
6 cartons ?
Absolutely!
Great update and Perfect weather too Keep em coming
Thanks mate!
Great video Stu, I believe the welder is an inductive load. The initial arc is most likely overeating the generators maximum rated output. I'm guessing the generator is a 6.5hp with 2.2kva alternator on it. You may need a 3.4kva or higher.
I see lots of guys stating video length .
Longer the better in my opinion
Highly entertaining enjoyable and worth watching
Who cares about algorithms and ratings
The 15-20 min format 2/3 time per week is very popular for Engineering/Restoration vids.
Have you given an thought to fitting a PTO to the engine before it gets remounted, I think that small crane won't be man enough once you start diving/salvage work with her. The option to go hydraulic at a later date would be priceless compared to the cost of the PTO now.
Yes, I have been looking at getting a PTO for it. Hydraulics would be very handy.
wow stu your comin on with the boat well done you even more so your summer is on its way so my son tells me in Melbourne great vid stu
For the plasma cutter, try plugging in a blender and fire up the cutter with that running.
And you could make margaritas while your at it
Or a grinder running but with no load. I think you are more likely to have that in a boat. The plasma cutter might not like the "noisy" current from the generator and running an electric motor off it will smooth it out a bit
@@erolaattori2317 Maybe a mounted bench grinder (cheap and handy) - the idea of a handheld grinder flopping about and taking off on its own doesn't bear thinking about.
in general if you have a tool or motor with a high amperage start load and a lower amp usage load you can use a capacitor to make the difference on start up
Yes yes yes timber boat will be awsome!!
Nice catch up Stu. We have used a genny for some outdoor gigs for our PA and had a lamp plugged in to pre load it. May be that would work for the plasma tool.
Make some locater pins (2 min.) and keep them w your bolts no measuring just paint the point or a light tap and drill your marks
Those pans are called hotel pans. They come in fractional sizes, whole, 1/2, 1/3 etc. and in depths usually 2", 4", 6". Can't tell for sure but it looks like the ones you have a 4" 1/4 pans.
It's all coming along nicely Stu :-) Nice to catch up with the new updates mate :-)
See if you can manually make the generator run at full throttle all the times instead of idling when under no load. Idk if that will do anything to the electric components in the generator but maybe worth a shot. Sounds like the ultimate solution would be a welder generator that you can portably weld from and use as a 120/240 generator but definitely not cheap.. might be able to find one used. Great videos Stu love the channel keep it up!
I'm excited for that engine to get back into service! Speaking of, when will you be getting the engine back?
In a couple weeks I hope.
So glad that you make these vids mate, thanks,
Glenno
Liking these more frequent vids stu. You should look into cable tie mounts or zip ties you may call them? Available in plastic and stainless. It's a good way to tidy bunches of cables.
Try hooking up an inductive load to the generator an ac motor works well like a blender or fan.
Will give it a go.
those pans that are stainless steel are called Hote Pans, they are used on serving lines. They come in different lengths
and depth, always the same width as far as I know. check with a restaurant supply house.
We did have a couple of different sizes, I'll have to dig them out.
And just like that it was finished .... it felt like 5 minutes 😢 .... keep it up Stu still really enjoying every episode
Thanks Nick!
When you rip the plastic board, cut it on an angle, say 30o so they can mate and put stops on the edges so the two halves don't slide away from each other.
Good tip!
Yes awesome video! Great work my friend! She's really coming together. Brandon - California
I've been following you for years and have enjoyed and learned from all of your videos. One thing has me puzzled keeping in mind that your business is yours and yours alone so this question is purely rhetorical. How does a man of your age manage to pack up his tools, quit working (at least it appears that way) to spend all of his time working on his boat. I'm 71 and could never accomplish that until retirement. How ever you did it good for you, keep the videos coming and this trawler series is the best on UA-cam.
Hey mate. Making the UA-cam videos is now my day job.
In regards to the plasma cutter, I would try running a motor or some other inductive load then strike the arc, a motor with a flywheel will act like an accumulator of sorts when the initial load is placed on the generator and help it overcome that initial starting load.
I'll give it a shot.
I have a Bosch angle grinder with a soft start. So it won’t work on a generator. Plug a regular high amp grinder into your genset and turn it on before turning on the plasma cutter.
I'll give it a shot.
Stu, those are 1/2 size steam table inserts. Full size double the length at same width. I know I can find them used in used restaurant equipment shops fairly cheap.
New in one shop, starting at $15.00 each for the 1/3 insert.
Thanks, I'm definitely going to try to find some more. :)
@@DangarMarine you can even get matching lids for them, that help make them stack-able.
just bungee them down naturally. ;)
Hope you get boat sailing soon.
Re-Organize, that means you move one thing into an empty space that isn't occupied with something you Re-Organized before this Re-Organizing, fair idea Stu, don't get that chance everyday to have that kind of fun Re-Organizing stuff..Looks good far as the Electronics but sealing the cords on the top..just read comment made by one or two gents, keeping with the flow gets ya closer to being on the go !!
I feel re-energised to have another re-organise now. ;)
I would be cautious with installing the strainer above the waterline as the impeller would have to draw water back into the strainer every time you start up
The highest I would personally install it would be with the inlet at water level.
Yes, I think I'm just going to have to put up with it being hard to clean and mount it lower.
@@DangarMarine it's a curse but we had a strainer barely above the waterline and ended up replacing impellers on a weekly basis, was not fun. But your situation may be different! Thanks for all the videos man me and my woman watch you religiously
@@DangarMarine also if you can source that external mesh it may prevent any large material getting that far a job for next time though
It might have been better to put the cable exit downover, if a hose on the engine bursts any sprayed water/diesel/oil will run out rather than into the chargers via the cable hole(even though they should be waterproof it doesn't last for ever.
Another idea is to put at least 1 start battery on each charger, that way if 1 blows you still have charge to at least 1 start battery and visaversa to the house batteries
the mental staying power these non-landlubbers have is really inspiring for me. just saying.
Thanks for the video.
Nice with the two chargers. Might consider having them plug into a box so that when they eventually fail, you can simply plug in a new charger instead of having to hardwire the new one. The box can then be wired to a rough duty extension cord for plugging in to shore power. Don't know what your electrical codes are there so better ask someone who is licensed.
Yes, a junction box on the same mounting board is a good idea.
Stu. The gennie you bought has 15amp breakers so is probably tripping those when using the plasma. U really need to get the one with the RCD outlets as they are rated to 32amp hope that helps.
Not sure about your Rcd's and mcb's. in Britiain and Europe we have type B that do domestic stuff and type C that are used with motors they hold the initial start up current.
I don't think they are tripping but I will check.
I literally laughed out loud when I saw the banana chair. Just pictured stu, covered in dirt with a beer surrounded by work kicking his feet him. Thanks for the videos stu.
A man has to have priorities. ;)
Eddie isn't getting the recognition he deserves. The channel title should be, "Eddie, with Dangar Marine."
It should be. :)
Refraceing the plasma cutter:: Oddly enuff sometimes when you put a long extension cord on it it works just make sure the cord is over sized... I use a 10 gauge.. not sayen it's right just sayen it works...
I'll give it a try!
@@DangarMarine Generators don't handle inductive loads very well, and a plasma cutter is almost completely inductive load. You may find plugging in a resistive load with the plasma cutter (something like a 150W-200W halogen worklight - not LED) will help the generator cope with the inductive load of the plasma cutter.
If you're going for a half decent winch, I think Sherpa Winches might have some good ones in the sizes to suit the crane, Worth checking out.
Thanks mate, I'll take a look.
You ought to rig a hammock over the afterdeck for those job well done beer moments!
I like your thinking Nathan!
Your Plasma Cutter might not like the output waveform from the generator. Some gennies don't output a clean sine wave, which could be "confusing" the power-supply in the cutter. Might be that you need to check the spec on the gennie.
I did a fair bit of research on the gennie before buying it. It puts out a pure sine wave, but I believe the frequency can vary with RPM compared to an inverter based generator.
You may be able to deal with the the plasma initial draw of current with a bank of capacitors.
What does that even mean?
Dont throw vital equipment like that loung chair away! Before you know it you throw other vital equipment like the beer cooler away :D
Never!
Hi Stu, I don't know if you plan on keeping the tool boxes in the lazarette permanently, but if so, either some ratchet straps or metal brackets are in order to strap them down. But you knew that, eh? Carry on!
Yes, I'm thinking I would like to keep some tools onboard permanently. I was thinking of screwing down through the base of the boxes as the drawers don't open if the top lid isn't up which rules out putting a strap over the top.
good one Stew..gees I like the bain marie tray idea mate..good recycling effort there..I especially like those two shiny blue kingchrome boxes mate..I hope they are fully stocked with all the latest matching spanners..Hope you have big padlocks for the blue girl though..wouldn't last 5 mins at 1770 I tell you..
Thanks mate. It is good to have the tools onboard now and fortunately it is a pretty safe area around here.
