Brian, I love your engineering mindset. You never jump to conclusions (like at the beginning when you are unclear whether Mastervolt has Bluetooth or not. You simply say "I don't know but here's WHAT I know ...". This is where a big part of your trustworthiness comes from. Love it. :-)

[@simonhantler8062]

i like the directors input "move your phone closer" good work blue.

[@vulturemunchies4692]

Not just technology but also technical sailing videos in general....... we want to learn everything about Delos and sailing around world....... thats the dream 💚

[@prankishsquire2663]

Off the track? Off the wall? On the beam? Outside the box? Do what feels good and keep doing it so well. Love ya.

[@diverbob8]

Great job Brian, I have spent a lot of time trying to teach people how to understand these terms and inter relationships. Looks like you have done a great job at getting your system up to date. One pitfall is the inverter. Many boat people threat their inverters like an after thought which is an expensive mistake if the ambient temperature derating curve is ignored. So the inverter winds up in a tropical enviroment buried in a hole with minimal ventilation and then they try to use the full rating of the unit. If you haven't done so, it would be a great service to your followers to get out the docs for your inverter and examine what happens to the output rating when it's in a ambient temperature of say 120° F or 40 to 50°C. Hope all is well....

[@TheCruisingKiwis]

Electricity is the bane of our sailing lives. Very interesting informative stuff, thanks!

[@davidc6510]

A great continuation of this 7 part series. Thanks!

[@robertadamsmetaldetecting6324]

Always enjoy Captain Brian Tech talk. Man is very intelligent and good at explaining thimgs.

[@andymauermansvsandybottoms4645]

Hey Brian. Thank you soooooo much for ALL of the videos you and team put out. I've pretty much watched all of your videos over the last few years... and now I've bought a sailboat. It's so cool to be able to look back and see how you did certain projects and see if what you did is the right thing for my Citation 34. It's an enormously helpful resource! THANK YOU! Andy Mauerman SV Sandy Bottoms

[@mayflowerlash11]

The whole description of the electrical system is valuable, not only for sailors but for land lubbers with a house who want to have a system of grid. Many thanks.

[@scs130773]

Thanks for confirming the windless question and a dedicated battery forward. Its something I've considered given the long run and the PO doing a crap job at running the cable.

[@mikecress3297]

I really like this series. It would be nice if this became a regular addition.

[@songsinthedrawer]

Hey Brian, KZbin algorithm brought me to your channel the other day, since I am always watching off grid power videos. Your tech stuff is great, and what a refreshing channel! Now I can't stop. After watching one of your videos, I am mellow and in the chill zone! Cheers my friend.

[@tedenda]

Tack Brian att du gör dessa informativa videor om era system på båten! Mycket intressant att följa!

[@elysiumsailing]

Thanks Brian, these tech videos are a great addition to the weekly videos. Thanks!

[@tommycook6039]

Please, please, please do more of these. My wife and I are new cruisers and I've learned so much for you that is helping to keep us safe and comfortable. Cheers!

[@tomgurskey8599]

You’re on the right track. I am in process of installing a Victron system on my cat now. More tech videos please. Thanks!

[@travisruse7834]

Loving the Boat Bit series! Please keep them coming.

[@strong002]

I use the same monitor in my RV and love it. Thank you so much for sharing.

[@JohnStec]

The explanations are very concise and clear! Teacher Brian!

[@itsvash679]

The Victron lineup for battery monitors is the BMV-700 and 702 (for 2 batteries) these do not come with bluetooth but you can buy a dongle add on. The BMV-712 is the bluetooth included model on the Delos. They come with a single 500 amp shunt rated to 96 volts max. The shunt is installed at the battery negative to measure all actual power flow.

[@paulsmyers203]

I think there has been a Victron firmware update in the time since you filmed this. My MPPTs now have a "Trends" screen where you can select from a variety of electricity monitoring methods to display on a chart over time in real time. It resets when you connect to the MPPT, and I've seen mine display more than an hour (graph is adjustable). It's kind of nice! Good for Victron for adding new features to their existing product line and providing them for free. I'll be buying more! ALSO! There are a few pieces of hardware from Victron for collecting all the usage information and uploading it to their cloud service so you can track the details over long periods of time and view it in a really nice web page. The data is shareable as well. AND! You can run the local app on your own Raspberry Pi and have it send data to the same free Victron cloud service, if you want to do it on the cheap. I think Victron have to be some of the coolest geeks out there.

[@fincaelmoro1869]

Keep these tech videos coming please, it makes you the stand out sailing channel, all down to Brian’s engineering expertise. Thx

[@riktigelaar8002]

Those boattech videos really help me a lot! Great inspiration for our own tech projects.

[@M_J_nan]

All these "specialtity" videos are great if you, like us, live on a boat for longer time. Keep it up! Greatings from Sweeden...

[@Cambuelkid]

Thanks for sharing your hard earned solar and battery experience...Much appreciated!

[@bimmergeezer]

Keep up the great tech videos. They answer questions I am sometimes too dumb to ask!!

[@sadiqmohamed681]

This is fascinating series, and Brian is a great host. It is a long time since I owned a boat, but I'm a retired techy so it is interesting to see how far things have come and how it is done these days. I've been watching this channel for two reasons. The tech stuff and how sailing has changed over the last 15-20 years, and the amazing video footage, particularly Alex's underwater stuff.

[@SoupyOatmeal]

I am tuned in to this series , keep going.

[@vraymond108]

I have a Victron BMV-712 in both my Sprinter van conversión and on my boat. I love the BT interface and even more the ability to update firmware via WIFI or cell service. On the Sprinter install i put a Victron 300ah Lithium battery so with the same IOS app I check the voltage and temp of each cell. Just the thought of being able to communicate with my battery is amazing. Now if I could just do that with my toaster I would be in heaven.

[@iamblaineful]

Victron makes really nice kit, love their stuff. Not cheap, but you get what you pay for in longevity and trouble free uptime.

[@LeighLino]

These vids are a perfect fix of you while away from Delos. keep em coming.

[@robertarmstrong3106]

I find these videos to be very interesting and would love to see them cover all the different systems on the boat. I am also interested in all the different things you do around the boat. Please include all the work you do that normally does not make it to a video. This is one of the best channels on KZbin.

[@progressiveokay]

Guys i love your tools, gear and technic vids!! Thanks!

[@larrykulesha1775]

Nice series congrats on having a baby.

[@David-ys9dr]

Enjoyed your small bits video on lit. Batteries. More please

[@appick01]

I've been loving the deeper dive into the systems it's really good info for people considering cruising or just upgrades to their weekend sailors.

[@peterdunbar4973]

These are really useful videos. I particular like that you are stress testing everything you have installed for weeks, months or years. Your movies are about the most up to date electrical systems like LED vs incandescent lighting, lithium battery banks, and multiple sources of charging. Once you have us all straightened out about power cables I would love to see easier explanations of troubleshooting NMEA connections. Is NMEA 2000 really the answer if you have a boat loaded with devices hooked up to the older standards? So many questions that you can help us to answer. THanks

[@svdelos]

Hey thanks Peter, glad you enjoy them! Good idea on the NMEA 2000 video, we have both networks on Delos and I have numerous devices all talking to each other so that one could be pretty cool. I'll add that one to the list. Fair winds and thanks for your support. Brian

[@jackjania9619]

Brian excellent video on power management. You should write a book on the state of the art of sailboat power system design. I’ll purchase the first copy.

[@paulhiguchi]

Great video Brian, you make things easy to understand. Thanks

[@RB9522]

You are on the right track in my book. Maybe you should start the EEBoat channel?

[@blainespaulding3197]

I love these tech time videos! Thanks!!

[@jodymooney255]

Love my Victron 712 with my Battle Born batteries! Thanks guys!

[@seafodder6129]

Really enjoy the tech videos. Especially the ones where something breaks and Brian has to put on his Macgyver hat.

[@mattlewandowski73]

As always, I appreciate the information. Lithium conversion has been added to my list of to-do's when I am able to get my boat. (And hopefully will be used on both my truck and camping trailer as well til then) Keep the tech videos coming. I am a huge fan of both your uncut long play videos and your tech/how-to videos.

[@SeanOBriant]

Thanks for these, I learn so much hands on from watching your "how to run a sailboat" videos. The travelogs are fun, but I 'buy you a beer" when I learn super helpful stuff on these behind the scenes videos. Please keep them going.

[@beebsisme233]

Boat bits I like it makes me not notice you guys are not on delos atm

[@richardmorholt1175]

Another great technical video, great job Brian!

[@peterfrebold]

....... awesome ..... waiting that you Brian are standing on the deck, maybe the fore deck or the side deck and controlling the whole boat in say a docking maneuver from a hand held controller box .... yes it will be easier once you have electric drive ...... Late, but still awesomeness, congrats on the wedding and the growing family Brian and Kazza ..... have fun be safe, save our oceans ......

[@erickeibler]

I am enjoying this series.

[@markjungmann1681]

Love the regular content and the new tech videos. Boat technology has come a long way.

[@JohnKimbler]

I really like this series -excellent information!

[@NMathew91]

Really appreciate these tech videos Brian, building a yacht myself and though no where near touching electrics or anything yet, it's still great to learn about the systems and system design to inform which way I go in the future. Keep em coming!

[@montyscooter1965]

These videos are excellent. Keep up the great work.

[@MrZipitydoallday]

Totally enjoy your videos .. but i'm finding these a bit short on time. Have a Great day (New ) Dad . And also the rest of the Crew.

[@sirroberttaylor9969]

All of your vidio's are extreamly informative captain,

[@Brzypoint]

It's so cool you guys are making this series! Excellent work!

[@stolas666]

Love that technical videos. Bring us more

[@valsa2]

Thanks Brian for the informations you give us. Always very interesting

[@pedropedroztravels8272]

Just bought the same monitor can't wait to see how it goes.

[@apick02]

I have the same unit as well, I love it! Only one annoying problem; some guy in my marina also bought the same monitor and now every time I turn the App on, it doesn't know which unit to connect to. The app displays both serial numbers and you must pick one. The serial number is on the outside of the box it came in..... Do yourself a favour and write that number down somewhere close at hand for that one chance that you park too close to a similar equipped boat. Cheers!

[@ericjohnson1322]

Victron I keep hearing great things!

[@sebastienmarceau8065]

Well done Capt.

[@thesailingkiwi]

thanks Brian

[@j.j.springer1099]

I had a couple Browning bows that were heavy draws 150 # and 80# but the batteries in the sites would last a month is you remembered to turn them off! But they did work good early morning and evening I used sr44 batteries 2 in each site! Was thinking about small solar cells to charge during the day but didn't get enough sun light in the woods even thou I was 15 to 20 foot in the tree! Funny ain't I? enjoyed

[@barbaralane9825]

Very informative-appreciate the effort it takes to present this information to your viewers.

[@edwinprins1563]

Excellent series

[@richardseagrist2647]

Definitely on the right track. Good timing for me too. Re-wiring mine right now.

[@bryanwatt9751]

Awesome, thanks for helping me fix my SOC alarm :)

[@1sheinz]

Love the series,keep up the good work. CHEERS AND FAIR WINDS Steve h.

[@murph914]

Love these videos. Reminds me of the pacific yacht systems guys. Wonder if there would be a way to monetize these. Keep it up boys.

[@blenkimcclapper7073]

love the videos the power system is awesome I was watching Danger Marine he was installing the same power system on his tug boat repair very cool stuff.

[@HopeOfJoe]

On the right track !! Thank you.

[@erikdaschalk3475]

Very helpful Brian, thanks!

[@tikiking3844]

Nicely explained

[@jerrodguidry3337]

Awesome series, keep em comin.

[@Pimptorious69]

Love the boat tech!

[@searchpei470]

Finally!....something besides sunsets and swimming fish.

[@rosserpace3602]

Great info from the operations side of sailing. Any chance you could post a pdf of your wiring diagram. I reproduced most of it from reviewing the vid but would be nice to know I got it right. Looking at a 2001 ASM now....time to start that sunset sail.

[@brianb6603]

Excellent as usual!!!

[@dalltm]

Keep the tech vids coming!

[@pmarr98]

Love this series so far

[@SV-DEDICATED]

Very helpful. More please.

[@JustinBellingerTV]

Brilliant, as ever. Really helpful to know.

[@johndixon5097]

Very interesting topics. Great job.

[@camielkotte]

Something tells me you really like the onboard electronics, you Brian, you nerd! Respect man. It is a really difficult thing to grasp if you don't have the appetite to understand. It takes a special Gene i think . You got it all sorted out now, please don't sell Delos! We want to know if your battery philosophy, monitoring et all works out.

[@lisadungey6257]

These are very interesting Brain thank you for sharing your knowledge with the tribe❤️

[@simonemezzedimi4054]

Brian, thanks a lot, I'm particularly keen on all your boat tech videos. I hope you get a minute to answer a question that is unrelated to lithium: you often show an handheld depth finder you use when scouting for an anchorage. Would it be possible for you to make a recommendation? It would be very helpful as I would need to import one. I tried to find a reference on your website but I didn't find anything. Thanks a lot in advance,

[@cellllman]

Brian, you do a great job of explaining technical things. I did not know the lithium vs wet battery differences but now I do! Love these tech moments! One question; I know wire size dictates how much power you can send; is there a difference in efficiency between lithium and wet when sending a longer distance?

[@spaleshi1]

Here is a really good calculator that helps you define the wire size required over the distance. circuitwizard.bluesea.com/ They have an application for your phone as well and I have used it often for running wire on our boat. Brian will have to answer your question.

[@ianmackintosh7278]

It is wire size and Voltage that affect current flow over distance not the batteries. The batteries are storage only, that is they have different storage, recharge and discharge characteristics and different recycle abilities thereby different length of life. It looks like Lithium likes long discharge and high recharge while lead like short discharge (less than 40%) and slow recharge.

[@MrAnnadrew]

love the boat fix videos

[@slamhead]

I would like to see a video of the actual wiring showing in series and parallel to the buss and how all the charging systems come together.

[@ianmackintosh7278]

Watch 1 of 7, it is in that 1

[@justforfux]

Could you get some footage of sailing at night with stars/moon. I know you need some high quality cameras.

[@sadiqmohamed681]

Alex has some great night shots on Instagram, and there is video in one of the recent weekly episodes. Several people have suggested she do a coffee table book.

[@douganniewall3429]

Helpful info, thanks from the tribe

[@robertgustavsson9817]

Ni är bäst. Jag följer er helt och hållet. Det blev ett svar på svenske men det skadar väl inte bland alla andra på engelska.

[@lisadungey6257]

Really enjoyed this thank you

[@jastark22181]

I love this series! =)

[@glalaxys]

First, I like these technique videos, nice to watch. I connected our victron bmv-700 without Bluetooth to a raspberry pi and log all the data that's coming in. So I monitor it over the internet from every I'm :) One question: What batteries you had installed before? Normal lead acid or GEL org AGM?

[@ahmetsezai]

Good video Brian!

[@beaudwayful]

Another great tech vid!
