Victron Electrical Upgrade - Project Brupeg Ep.363

[@Cameron-ur2tk]

you should use a thin piece of plastic above the the battery terminals incase a battery comes loose or just wiring it up. I imagine it would be square and span the entire aluminum shelf held in place by a couple rivets and some adhesive. . Having those posts accidentally touching the aluminum above would be quite the arc.

[@svfirefly2702]

17:11 can confirm that going significantly bigger (600’) doesn’t erradicate the awkward spaces, it just multiplies them and forms them around bigger gear!

[@JaySea1069]

So pleased I could help solve a problem and it passes muster with Dame, Cheers from the Pine Tree State!

[@ChrisHarding-lk3jj]

You should be using c10100 copper bar stock for bus bars.

[@miningwayne935]

Good luck accessing those rear battery terminals! And your hold down clamps.

[@jackdbur]

There are these things called rivnuts/nutserts that are squeezed in like rivets that make jobs like those much easier.

[@zachpulsifer8446]

Did NOT expect a shout out for the Pine Tree State!! Fellow Mainer here, wicked cool gift Joel! Hope Brupeg can make it to the Gulf of Maine someday! Cheers!

Mainer here as well, caught me off guard when I heard pine tree state!

[@corezerostudio]

My Cuz! Genius in his own right!

[@TravelsOfBillandLaura]

Love the channel! As a live-aboard sailor, I can say that much of the work you are doing now is spot-on. For example, we have the same Balmar regulator and it has been running error-free for 13 years. It's like programming a 1960s computer but it works! Thanks for sharing your journey.

[@chrisevans8455]

Very exciting. Please extend to Duncan our very best wishes for a quick and complete recovery. He is one of the standout Brupeg crew. We look forward to having him back on board.

[@Pinworthy]

The rocking of your ship will cause the batteries to move in that box and they will end up rubbing against the threaded rods. That will cut into the battery's plastic cases which could cause a short circuit that would lead to problems. Better to fix it now than later... But what do I know? I'm on the other side of the world... Good Luck and best wishes, Pinworthy

[@kenrolt8072]

. . . . and with enough movement the positive and negative terminals on each battery could contact the aluminum cross beams . . . . Add electrical insulator tape wrap just in case

[@thatdave86]

They could add stainless ratchet straps to hold down the batteries,they are used in Ski Racing boats and even offshore racing boats,holding down the battery or batteries.

[@jossmaxwell00]

Jobs getting closer to being completed regarding the electricals. Much kudos to jess and dame for this. Duncan I had a mechanical Aortic heart valve replacement done in 2015. Still going strong today. Good luck mate on your recovery.

I saw the last video about the placement of batteries. The went right in according to your plan. Cherrs and hugs from Norway

[@davidbatkin3976]

Good work Damo, Will be interested to see how you get cables on the battery terminals in such a tight box , but I’m sure you’ll come up with a crafty solution !

[@stuartburke5371]

How are you going to tighten those rear battery terminals, once the battery cables are in place. We build the box where you load the batteries in from the top.

[@jaymarlin3565]

You two have such interesting friends. AWESOME..!

[@TD_YT066]

Hope you put something between the cross support bar and those battery terminals. In heavy seas, if the lower battery were to bounce and touch or the top battery from impact to a wave, bent that bar down, the terminal could spot weld to the bar and almost certainly cause a fire if there is not an internal fuse inside the battery. I'd have moved the bars so there is no chance of the terminal touching it.

[@dominicbrant1968]

I did wonder about that, let's see what they've planned.

[@TD_YT066]

@@dominicbrant1968 Heh, cliffhanger for next week ? :)

[@kenrolt8072]

aluminum cover to replace the acrylic would buy time if you had a fire inside the box. Add a warning sensor + alarm for this purpose.

Hey guys. Looking forward to going through your vids to avoid mistakes on our project. Dad has been watching you guys for years. We’re just starting our rebuild of a 65ft ketch that dad built.

[@kaydog2008]

Happy to see Jesse is doing much better she’s such a troope and working her a$$ off.👉👉A slide in acrylic panel with seals and handle from the top into a tightning stainless angle rail clamps to seal with wing nuts to push the glass against the seal would have done a perfect job as well. Plus it makes for easy access with NO tools needed.

[@slashnburndotcodotuk]

That gear keeper is a much better solution to the bungee cord I suggested...

Crikey........ The privilege is ours, to see such an amazing project come to life! As always Massive Respect Leave, Same or Better, Everything Be Kind ☮️🙋🏻‍♂️

[@davidlecottage]

Whilst the lithium batteries do not vent any gases, they can go into thermal runaway which can be caused by charger overheating or internal construction failure. In either case the gases are very toxic and at high pressure and very hot (1400 deg C). Please check that the aluminium case and nylon connectors will provide sufficient protection - the box will probably need thermal insulation. General air ventilation will be required as they can get hot when charging.

[@purplebooger6410]

I do a very similar copper bar connection on very large car stereo equipment all the, for mine I flatten copper pipe to get the copper buzz bar and when everything is assembled and working I rattle can clear coat all of the copper and connections to prevent corrosion. It lasts for years with regular maintenance without any corrosion problems outdoors in an engine bay and never produces heat with 250amps and more at 16 volts. Good long term solution! Also I vote yes for a bigger Brupeg in the future!!!???

[@Pinworthy]

You should use some PEX pipe to cover the threaded rods in your battery box.

[@BillyBob38846]

Good job! Everything is coming along great and it won't be much longer before Brupeg is on her way. See yall next week, take care guy's! 👍

[@gordonagent7037]

Damo, have you made a list of all your essential electrical switches, components etc so that you have spares available if they fail at sea. Also, have you kept diagrams of pipe work etc so that if anything should happen to you at sea others will have some ideal. Also, what about some nameplates, valve descriptors etc. just a thought as everything’s fresh now but you don’t want to have a problem down the track. Also, please convey everyone’s best wishes to Duncan, hope he has a fast recovery because I’d love to have a beer with Duncan cause Duncan’s me mate. Catch ya next week guys, have a good one

16:58 - "Vetoed!" You tell 'im, Jess. 😁

[@finnna8352]

Two things, those battery posts are awful close to those cross members in the box. It looks like wiring to those back terminals is not going to be easy.

[@mungbean84]

That seems like one thing, but I completely second this. Even doing the hold downs is gonna be a proper pain in the proverbial...

[@1425race]

Nice work with the battery install, isn't it great that they are a quarter of the weight of lead acid. Re stainless fasteners into alloy - although you put nylon washers to insulate the head of the screw from the alloy there is still a risk of corrosion from the thread piercing the alloy.. We use a very good product in NZ called Duralac. This is a lanolin-based epoxy sealant that sets hard and totally insulates the whole fastener from the alloy. Should be available in Aus - worth a Google

[@MsJon52]

good vid, its great to see your progress, on the subject of pants I highly recommend dancing pants, of the correct size of coarse, the reason being they are great for ballroom and ballroom dancing, lol

[@j.hoppli4657]

wiring the batteries will be much fun... in which way the cables come out of the box?

[@dcallan812]

Ah boat Yoga, its good for you. 🤣🤣 Great update 2x👍 cycle shorts would be a nice change ☺😉

[@president2]

Love it so much keep it up as always 💘

[@jaffasoft8976]

Could put a nice cut DIY gasket of rubber between the aluminum plate and the devices bolted on the engine plate.

[@kaharry055]

Just a suggestion in case you haven’t already done so, you could slip lengths of tube (garden hose or clear tube) over each of the threaded rods which hold/clamp down the lithium batteries to prevent the thread chaffing the battery case with movement over time. As the batteries seem to be secured in the centre there could be potential for them to wriggle with the movement of the boat. Also did I miss where the cables are going to go through the battery box to connect everything up?

[@ProjectBrupeg]

You didn’t miss anything, the cable glands haven’t been fitted yet, was waiting until Damon is here to be sure he is happy with gland layout before we cut the holes for them. Chafe won’t be an issue with these clamps. If the batteries are moving such that the threads can ever touch the batteries we haven’t done them up. Once done up the batteries cannot and won’t move.

[@robinvoice-ln4rh]

I know that it is too late but l do wonder about the aluminium battery box, why ally? Why so tightly packed? Murphy says that any spanner work inside that box will cause sparks. If the box is designed for ventilation why not plywood but I am attracted to racking and a bit more space around the batteries. R

[@ProjectBrupeg]

@robinvoice-ln4rh the box can’t be made any physically bigger or it can’t fit down the hallway and I to the wheelhouse. If we made it from timber of any kind the thickness would increase and make it just as tight on the inside (admittedly not conductive).

[@jimcalver-oj4xf]

Interesting, the battery box. Very nice as per most all your work. However, how do you plan to maintain the terminals on the batteries? We have 4 x 200 amp-hr 12vdc on our 43' trawler. I check the battery terminals every 6 month and have found somewhat loose bolt connections, even though the OEM (stainless) lock washers are used. The threads are greased with no-alox so no locktight used for better electrical connection. Torque down again and cross fingers. I also check with a non-contact thermal gun to see if any connections are heating during high current conditions. ALSO, please bond the metal battery case to the DC ground. Or, check that the metal bolts connecting the battery case to the floor are a good electrical connection back to the common DC / AC ground point. Good luck!

[@bubblez_x_beast8721]

Excited to see what new furniture you guys get in the space, admittedly I was really hoping you'd replace it soon 😅😂 the boat is too nice to have subpar furniture!!

Fitting out the interior is a whole new chapter, and at least another go fund me down the line..

[@jonahrens1274]

[@waterwonderland5667]

Lithium batteries do not need to be vented since they do not produce hydrogen gas. They may need to be ventilated to prevent overheating though.

[@Amonephis]

yeah i've been confused about that since they built that box, the only time they offgas is when they are on fire but you got other issues at that point.

[@chris7643]

It’s law in Australia now to vent lithium to the outside world

[@mojo6524]

Heh Q&A gave the box a CAT SCAN!

[@halburtonwarrington-minge3434]

Really needs a Lab report though! and a PET scan.

[@Bullshit1011]

Great work guys .❤

[@greens007]

Couldn’t you just have mounted the battery switches onto a (wooden) shim to negate having to bend the copper bars?

[@1breematt]

For none experts...Pease cover the battery terminals while installing. In case they strike the alloy at the same time

[@tas32engineering]

Confined space money in the torpedo tube wasn't worth it when they shut both doors. Nice to be near to safe departure. Do you have the items that you can't get easily once out to sea. Good to have 1 or 2 extra crew. But safety is number 1 once out past the seawall.

[@secretsix6]

[@ThePaulv12]

Remember the Chockfast dam imbroglio? We can all have a laugh now.... Inline 6 engines are naturally very smooth - in fact smoother than a V8. Just because a V8 has more cylinders doesn't make it smoother. The characteristic V8 beat is demonstrating the issue. I can't be bothered going into it. Inline 6 has perfect primary and secondary balance - the only real issue with them being the long crankshaft which can be source of torsional vibration under high load at certain RPM but the large mass of the front torsional vibration damper controls that. Plenty of cat in this vid. I like that cat. I feel cat will adapt well to a life at sea. It might take a bit of time. I'd suggest letting cat go where cat wants to go when underway at first. There could be a few 'sick up' incidents but soon enough Cat will find a nice hidie-hole and will eventually become a fully fledged bold sea cat, sitting on charts in rough weather while you're trying to read them and doing all the annoying things we love to hate about them.

[@pmacgowan]

[@jackhammer4585]

Noticed some maybe hydraulic/water high pressure hose in the electronic/battery room? @11:22 Will that location be permanent?

[@ProjectBrupeg]

It’s stainless water pipe. Unfortunately it’s not possible to move that pipe work to a different location. It’s sealed up tight with threaded fitting and no hose clamps in sight, and we have drains in the battery room should a leak ever occur. A lot of discussion with our two electrical guys has happened regarding these pipes and they are both happy with the solution we have in place

[@johnjohn-ed9qt]

16:55 I, and my coworkers, can attest that no, a bigger boat won't help. In fact, the bigger the boat, the more of those fiddly little spaces can be crammed in. (We have done many a repair job on a >300m container vessels. In those spaces. That the path to, from the gangway, involves a number of other such.) I would curse all marine engineers for designing such, but if they didn't, my income would drastically drop.

[@gregorythomas333]

Just curious...where is the fresh air intake for the batteries? There needs to be flowing air in so it can be sucked through...then flow out through the exhaust vent.

[@ProjectBrupeg]

Lithiums don’t require air. This vent is in theory never going to be used. Its only if the batteries ever off gas (not fire as these are lithium iron phosphate batteries not lithium ion).
