Sunt câteva lucruri care trebuie ajustate pentru că nu aveam toate barele de care aveam nevoie. Dar deocamdată, faza unu a electricității este terminată și sunt atât de încântat de cum a ieșit.

Now is the time to straighten up and label all those wires (both ends and mid-span where you will access them). At least make a block diagram what runs where and what fuses or breakers are controlling this or that. This allows you to asses wire size, etc… to make sure you have adequate wire type and size and don't overload any one circuit. bryanirwin5473 just gave you some valuable "save the boat" and "keep you alive" kind of advice. Wiring is extremely time consuming so be patient. Use good wire (UL rated). Stranded copper only. Stay away from cheap Chinese wire, especially the large conductor runs to or from the batteries. Even high enough DC voltage can kill you so be careful.
You have to isolat you different battery types. Set up to charge agm off of engine or solar/wind and charge lithium with a victron DC to DC charger. Make sure you have ample air circulating around lithium Bank. Or have lithium charge agm dc to DC unit. Over charging agm can get them very hot, ruin them, and they gas off bad stuff. House bank and engine bank should be separate systems. I'm a sailboat technician and you can ask me any question you want. I love to see you taking this on. Go for it! 😊
Too late now, but didn't the hydraulic crimpers have a set of cutting inserts? Good to get a pro to do the complex stuff. A good decision. Make sure your new breaker panel has lots of space in it. As you live in the boat you will find you need more circuits.
Oh man, watching you struggle with those battery cables, those are a PITA with the right tools, let alone those. That crimper sucks, and no real cable cutter? Glad you got it finished, though.
that's a huge step foward, but take the time to diagram the connections and lable everything. It makes any future changes so much easier.
I'm very glad you got that done, and a lot of it looks great, but there are a couple major things to watch for:
1. Battery straps. I didnt see any, and those puppies need to be strapped down.
2. Circuut protection. Im guessing the lithiums are your house bank. Circuit protection is supposed to be within 7 inches of the batteries, or uo ti 72" if you run the wires in loom. I didn't see any circuit protection, that's no bueno.
3. As others have pointed out, you can't have lithiums and lead acid, including AGM, connected directly. Their chemistries are different, charge profiles are different, etc. The list of possible problems is long and significantly reduced battery life is the least of the issues. Best practice afaik is a DC/DC charge converter so that the two different banks are being charged properly.
I'd also put better boots on those lithiums on the positive side.
Great to see you making awesome progress. Your channel is one I'm watching as I keep my energy up as I get ready for my boat remodel. You're an inspiration, keep it up.
I'm an ABYC certified marine electrician so feel free to ask Q's if you want. I do this stuff every day.
Fantastica
Very neat wiring Nicole, but some very important things to note as an electrical engineer. NEVER mix battery compounds, especially lithium and AGM/Lead acid as they have different voltages and more importantly, different charge profiles. It doesn't look as if there's a Battery Management Controller on the lithium to make sure that each battery has it's voltages and currents balanced and monitored (safety). Do not connect an alternator to the lithium as when they reach a fully charged state, it will destroy your alternator. Best to charge the AGM on a correct charge profile and then use a Victron DC to DC charger to charge the lithium. Solar/wind can go straight to the lithium.
As the batteries seem to have been paralleled on a terminal block each battery post should be fused (at the battery) to the maximum current rating of the cable. This is to protect the batteries from short circuit. You must then fuse down each step progressively smaller as you go. I love what you're doing and love your cutter. You do some great videos and thank you for taking the time and sharing your journey with us. T
🤠👍
Those new lithiums are NOT connected correctly.
They will not be able to Balance correctly.
They need to be wired in Parallel Correctly
with ONE positive out from one end of the bank and the ONE negative from the other end of the bank. I setup Lithium batteries and Solar professionally in business.
I assure you that is incorrect.
I sent you a Diagram and better explanation on Messenger.
Yes, it is better to parallel the batteries directly first. That is, connect all positives with 3 short cables & all negatives with 3 shorts cables. Then connect the positive of battery 1 to you positive buss bar and then connect the negative of battery 4 to the negative buss bar. Connecting this way make the battery perform better as one big bank. The buss bars should be for connecting to the DC panel, inverter, solar, generator, … but not for combining batteries. Also, one of the battery lines going to the buss(pos or neg) should be fused using a good fuse like an ANL fuse. As you have it now, you would need 4 fuses.
Why 2 AGMs? I don't think that 2 are that beneficial, but I agree with keeping the start on a lead acid based battery. This way you can connect your alternator directly to the start battery and use a switched battery combiner relay for safely and cost effective combining start to home for charging. I use a Blue Sea ACR but you could use a $25 Dewinner VSR. Just put a manual switch (or smart switch) in the small negative ground wire. With LiFePO4 batteries, the 13.2V or more always trip the combiner but with a simple switch, you can control this.
Great day to detox (sweat) you’re amazing!
I am single also and when I have to do work around my house, that’s a bit much for me. I find that if I just go and ask a man for help, he is always very happy to help me. As he thinks he is rescuing a damsel in distress. I always repay them with a great sandwich or some cookies and I try to give them some money but usually they won’t take it. So I know every man loves a good sandwich. I think the guys in the yard would be willing to help you if you just ask. You’re very sweet I’m sure they would love to help you.
I'm totally in-aw of what your achieving your are amazing …..well done…….
Pain is mandatory, suffering is optional, wrote Haruki Murakami. Soon you'll be crossing oceans and this will be a distant memory. Take care!
You need a boyfriend (on so many levels)(which shoudn't be a problem … where you are..they just might be total losers)..Pro Tip: Most Bun men are losers.. but some are trust fund groupies… look for them
Awesome job
Awesome job Nicole !!! I admire the passion you put into your projects , don't give up , your are absolutely right , it is all worth it.. Big hug😊🐳
It's well after the fact, but the 4" disc grinder you were using will cut all the heavy cable when a cut-off wheel is installed. It will leave a very neatly cut end. Slide your heat shrink over the end before removing the insulation.
Just incredibly happy to see you genuinely smiling and excited to keep going. The electrical guy did an amazing job with the wiring. And frankly, the mess that got created due to boat projects is nothing to be ashamed about, it shows that you're making progress with the projects. Keep it up, you're making great progress
Those battery terminal crimps are a pain in the neck, aren’t they? You need 6 hands to do it! And glad to see you with a smile. Getting boat jobs done is satisfying, isn’t it?
Do you get a lot of random marriage proposals?? I’m going to refit a sailboat next summer and I fantasize about someone like you falling out of the sky and landing on me… softly of course. Anyways, your actual realness is incredibly refreshing. Please try to enjoy the suffering of building your boat, if it is possible. I admire you for your honesty with all of yourself you are willing to show. The good and bad. And I wish there was a way to convey how absolutely amazing you are
Keep up the great work, really look forward to watching your new episodes every week!!
Once again Nicole ( alias Superglue )…..I can't help but admire you for what you do on your boat and in front of your camera…… You are just so Honest with your viewers and a Fantastic Role model !
I always look forward to anything you do ! Glad your injuries are healing ok !
Love from Australia ⛵🦘🇦🇺🌹
Not an electritian but I believe the AGMs and Lithium cannot be connected to the same system that then connects to the alternator or solar/mains charging system, due to very different charging requirements, at least not without a dc to dc converter between the agm and the Lithium. (Ah TerryFrySax says it so much more precisely below)
Many just dedicate the agms on a circuit to the engine and anchor winch and then seperately circuit the Lithiums to the main circuit board for the rest of the boat and then work out seperate charging methods for each or , again, get a dc to dc converter in-between.
Also Lithium will burn and can explode if immersed in water so be mindful of placement and keep a weather eye on that locker. You cannot put these fires out as they create their own oxygen.
It is great you are removing the dodgy wiring. Good luck, someimes it is easier to just nuke it all and start again rather than trying piecemeal.
Oh, I found hacksaw or cordless grinder useful for those large wires, or medium bolt cutters.
All this is probably too late of course.
Also as said below, label, label 🏷 worth getting a labeller or white electrical tape and texta.
To add to ease of disconnection (also mentioned below) run the negitives from battery to battery to battery then one to bus bar. Shorter span that way, less rats nest. As said below, parallel the positives as well. I take it there is a 3-way switch so you can turn to just house batteries when anchored or sailing to save your agm start battery? It wasn't clear.
Praise on tackling this.
When I am frustrated working by myself, I watch your videos 😂. You’re a trooper!
Fuse on lithium batteries needed. B2B needed to protect alternator
Great video
Next time use your grinder with a cutting disc will save you some time.
Super lady, fill my heart, much love. Shamim zahuri from bangladesh 🧜♀️🦋🫂🤍👫🤝🎎
Even those of us that do wiring often kinda dread doing it. It's definitely a normal reaction. If you haven't already, strap those batteries down. None of us want to be in a boat that rolls over but having one less catastrophe when we do would surely help.
I prefer a more modular set up. Smaller systems dedicated as navigation, lighting, living, engine, emergecy pump. This way you could have lithium and lead, and since lithium batts dont offgas you could seal them in a compartment. ☠️ max resiliency 👍
4000 pounds lead ballast in the keel. I would prefer 4000 pound steel framed lithium battery pack. 👍☠️ Monst⭐️rNauticals.
🇹🇷🇹🇷👍👍
"It sucks right now, but it's worth it." Remember: you can have it done right, done fast, or done cheaply – you can pick only two of those at the same time. I would always error on the side of doing things right.
I love the way you are you inspire us keep it up stay strong chasing your dream of being free, from Cuba Oriol
2:50 hmm 🤔 you are definitely 1 of a kind and it blows my mind!!!
Very precious ❤ not sorry for being honest 🤠 ⛵️
♥️♥️🥰🥰
Nicole, did you incorporate a Battery Management Control System? Nice install you should be extremely pleased with the new arrangement. Merry Christmas!
