Thanks a lot for watching! This video was a really techy one and it was probably too much for some of you :) But if you would happen to be one of the viewers who found it interesting and maybe are about to do a battery replacement yourself, we wrote down some useful things and links over on our Patreon page www.patreon.com/ransailing We wish you all a great weekend! Cheers! /Johan, Malin & Vera
I know some prefer just the cruising aspects of your videos. However, I believe that these videos - the refits, upgrades, and maintenance videos - provide valuable insights into ship ownership/cruising that isn't necessarily seen otherwise. So please, keep up the good work. Been watching for years now and I intend to keep watching.
It’s part of package ! Sailing , maintenance , hiking , exploring ! I love them all ! I loved when you replaced the mast and rig !!!! Keep like this ! Still awesome !!!!!
Crazy, wonderful Russians. On boat maintenance: sometimes I think that patience is the essential quality. I just loved the electrical overview. Johan is an excellent teacher.
They really should be using steel beams instead of aluminum. The Young's modulus is horrible. Those guys are going to have a tough journey. I hope they are fortunate with weather, otherwise, they they are in a world of hurt. Hope they have an EPIRB and a decent liferaft.
I know NOTHING about sailboats. But i would buy, sight unseen, a boat from this Gentleman. His knowledge,attention to detail and the ability to figure out work arounds if needed. They are always needed. bra gjort sir
Except the last boat he sold had something wrong with the keel. It had separated or something which may be the reason they sold it? I don't know. I'm sure he told the buyer. They discovered it on haul out in Vancouver I believe. Correct me if I am wrong.
Johan: "I realize this video isn't for everybody." Me: This was actually the reason why I started to follow your channel. I love the nerdy technical stuff. :-)
Johan, this episode was both informative and entertaining.I'm a simple fresh water sailer but the complexity of a modern boat like yours demands a great deal of research, planning and knowledge when dealing with multiple systems, voltages and battery types. Your explanations are excellent and the attention to detail is very professional. Well done.
This is the best example of a high quality DIY LFP build on RU-vid that I have seen ... and I have watched a lot (and built my own). The use of 12 volt lead acid as a safety buffer, back-up, and for long-term storage is an excellent feature. That X2 BMS is, I think, the best available, I hope one day they will get a bit cheaper! Anyway ... good job.
Sure, scenery is great, Vera's antics are charming, and your history bits are interesting, but I like that you show us the whole picture of boat life which includes maintenance and tech stuff. Hope all the stuff you installed works as planned. Best regards, Gloria
Johan, if there were a Michelin star awarded to boat owners...you'd have 3. My husband and I watch many sailing channels, but yours is our favorite, and I'm a patron. Anyone who buys RAN II will have a gold mine.
Johan, well well you never thought that people would be that interested in battery 101. Well I for 1 am very have to learn something new today, granted it only a brief overview but none the less very informative. Thank you for do this .
⬆️ YES, watch again and again & take heed - listen and pay attention, specially about going for a parts run; witch will be several times! And, the project will take days, too.
The beauty of the internet means if a video is boring to someone, then a quick click fixes that... Tech vids are great. It's comforting to listen to a knowledgeable commentator, rather than a sales man... Practical experience can be expensive if it goes wrong, so intelligent overview is everything... Go you...
A fair amount of boat life is boat work , if those who only want to see the cruising tried it , I’m sure they’d get a rude awakening 🤣 good video , good content keep it up . Cheers 😃🥂🍺
Outstanding. I hope you realize how respected you are in the community. Your knowledge goes way beyond normal information and you always bring it one step higher in your descriptions. Thanks J.
I'm 90 years old and stopped sailing in 1995 when I sold my 31' sloop after cruising for 25 years. It used to be enjoyable with a gasoline engine, a 12 Volt battery, a compass and a radio direction finder. That was primitive sailing compared to what you folks are doing but a lot of fun which I'll never forget. Of course, you're preparing to sail around the world so you need all of your upgrades. I look forward every week to see your latest video. Thank you for every thing you do for all of us.
To be honest these are the only types of videos I watch now. Seen enough off the sailing vlog style. I just like the electrical and mechanical videos. And videos of sailing, navigation challenges etc. ❤️
Absolutely fascinating, Johan. Your knowledge, and technical expertise, are an inspiration. We enjoy your cruising, of course, and your hikes of exploration, and history, and your everyday domestic life on board. Please also continue to impress us with your boat maintenance, and upgrades
While the girls are away the boys will play. What a wonderful project to play with. High tech power upgrade done right. The system looks completely thought true and the installation done right. I am looking forward to see the performance numbers. Well done.
I enjoy these videos alot but I'm a nerd so there's that. I've wanted to sail since I was a kid and it amazes me the technology that we have today to make living on a boat much more comfortable and safe.
Great video Johan. All of your improvements to Ran II have been extremely elegant and show a great deal of ingenuity and a high level of quality installation. Very informative and well thought out. Meticulous is the English word that comes to mind. No shortcuts for you. Bravo!
I don't have a boat but I am installing a solar, LiFpo4 battery system along with necessary controllers and wiring. So yea the more different installs I see the better my general knowledge of how it all works together. Thanks a bunch.
Fascinating approach to make a deconstructed battery system. Normally see the cells and bms all package together into an enclosure like a lead acid battery. I like your approach better having open easy access to all the parts allows for easier troubleshooting if issues ever come up.
I was surprised, and pleased, to see the Russian boat. For some reason, I never think of Russians having a yachting community, particularly Siberians! It was interesting to see, thank you.
I'm a beginner to sailing,just having finished few basic ASA courses..I've been watching many other people who document their sailing travels, and you folks are, by far, the best to watch in every respect...
Johann has to be MVP ( Most Valuable Player ) in the cruising world - need a World Championship of Cruisers fixing stuff 🤣 - Johann, Brian on Delos, Bobby on Doodles and, of course Riley - feel free to add other contenders 😊 all stay safe and well
It is interesting to see your work on Ran because sailing the distance you intend to do knowledge of all systems will get you out of any situation that may crop up, Thank you for your effort.
Your equipment has to be maintained whether it is sophisticated as your sailboat or is a stone age axe. I find it interesting to see what it takes to keep y'all sailing.
Johan ... I love your technical talks. You are a master at decision making, making it work and steering the explanations along. Your voice is also 'easy listening'. I have always loved the 'behind the scenes of life', so so interesting and important. I'm trying to follow your 'leads'. And as for those Russians ... no surprises. Incredible!!! Thanks again for your special 'mix' on RANII. Hi from Australia. Wish I was there, I truly do.
VERY Informative!!!!!! THANKS for Sharing and taking the time to Break it all down....AND we did catch a Glimpse of Captain Vera too, SO Its all Good😁👍👍👍
Really liked the video. I laughed when you said you didn't want to make it more complicated, though. I also laughed when you went to the store a few times. I feel your pain.
Very nice setup. I was wondering about the connection from the engine alternator to the batteries, but was glad to hear you say that the lead-acid batteries are always connected.
Wow! Very impressive craftsmanship. The work is first class and the explanation and video is as well. I enjoy all your videos but appreciate the project videos the most. Keep em coming.
A very well done video. Seeing a beautiful work of art, say Vermeer's Girl with a Pearl Earrings is wonderful, seeing how did the work would be outstanding. ⛵👨👩👦🖌✏✏
You can simulate the heat shrink with waterproof adhesive by smearing hot glue on the wire then sliding the unglued heat shrink into place. The heat gun will then melt the glue as it shrinks the tubing. Works a treat.
LOVE your technical stuff ... I'm going litium on my boat as well ... and I share your interest in building my own battery pack with BMS. Regards X-95 🇩🇰🇸🇪
Very good tutorial of a highly technical subject.. The continuing demand for more and more electrical power is a challenge but essential for the Radar, AES and GPS Nav plus electric cooking range/oven and refrigerator/freezers . The real plus is eliminating the propane system with the problem of refilling bottles with no two counties using the same tank valve. connectors.
I don't have a lot of electrical experience but it seems to me that it would be a good idea to make a drawing of all of this in case you need to trouble shoot an issue in a hurry in the future. Trying to remember all of this while under stress might be difficult. I appreciate your making this technical video; very interesting.
You can get lube for pulling cables that evaporates fairly quickly over time. But gel hand sanitizer works if you have some on hand. I only mention as the next cable you will have to pull through that cableway is going to be tight
It's amazing how slippery gel hand sanitizer gets when wetted with water, even several minutes after it's apparently dried on the hands. Trying to unscrew a cold water bottle with condensation droplets 💦 on the surface is easy with dry hands, but not if you've sanitized your hands within 15 minutes.
You LOST ME somewhere near the very beginning but yes, it was honestly very interesting to know how safe and well protected your boat is, electrically, in all situations. Secondly, I can only say that "those two ladies" of yours, are in very, very safe hands. Good luck for the rest of your tasks and I can't wait for you to start your next adventure.
The refit is very nice work, however I'd like to broaden the discussion a little. 1. We used a specialised small sealed lead/acid battery for engine starting alone. It allegedly gives a starting current of 1100 amps and is only 200 by 100 by 100 mm. and has worked without maintenance for at least 15 years. 2. I have considered placing a specialised battery for anchor raising/lowering in the bow with small diameter charging leads rather than using a main battery with very long high current capacity expensive conventional leads. these might be worth considering as alternatives; though I must also say that your enormous battery capacity must be very comforting.
Very impressive video on a smart combination of old/ cheap and new/ more expensive technology. I was supervised to see that the charging bar is loading the lead acid as well as the Lithium batteries because usually they have divergent charging curves and are not supposed the bee connected together whiles charging. I am very curious to see how it will work out in the future. Well done and excellent explanation Johan. Thank you so much 😊 🙏👍
I have a lead acid 2400 watt system for the solar system in my house in Mexico. It was very clear hearing you work through everything. The next time I need to get new batteries, I will consider moving to a lithium battery system.
Hi Johan, people who mentioned the cable length needing to be the same is because of a different resistance if they are not the same. In your case it looks like the entire bank is connected in series to the BMS and charger so it will not be an issue. If you had more than one bank then each would need the same length cables.
That was a really well put together video, no need to apologise, keep the videos coming, lock down maybe easing, but i think you have alot of ppl hooked
A lot of it was way over my head in technology, but you certainly know what you are doing. It will be a very reliable system, and best of all you will know it intimately if it needs fixing.
