Ryan’s nerdy guide to lithium batteries on sailboats (VS lead acid)
This week, Ryan shares all the knowledge he has of lithium batteries from the company he once started with his once college roommate, and why we are installing lithium batteries on our sailboat.
Ryan goes through all the advantages of lithium batteries, from size, weight, charging time, charging cycles to temperature range and useful power.
We go through the different type of lithium batteries out there in the world and compare the price between lithium and lead acid batteries. Ryan even answers some questions regarding having lithium batteries on boats.
In a different video, we will show the installation process.

Hope this info us useful to you! We are installing those batteries in a month, and we'll make a complete installation video. Are there any particular aspect of the installation process you guys would like us to show/describe? Let us know!
Well done Ryan! You could sell and Eskimo pie to an Eskimo! Like Sophie able to talk the paint off the walls!
Looks like a little short term pain for long term gain. Nice job capt.
I'd like to know what type of batteries Sophie runs on, also if you have a carbon monoxide detector for the batteries should they fail and outgas when you're asleep.
Excellent presentation
Show it all!! Love all the detail!
This is a great explanation of the different battery types. I spent yesterday learning less than I just learned in your video. As a sailor on Lake Superior, I just found Dakota Lithium online before viewing this video. Dakota Lithium has numerous "packaged bundles" for different van life or weekend sailing applications. This is EXACTLY what I needed to better understand what to buy and install this upcoming Spring. Thank you!
Ryan you gave an Excellent informative presentation that even an old 64 year old can understand! Well done. GOD bless. JC
I love the high tech "post it" graphics. Keep the videos coming. Thank you.
best lithium boat video I have seen. This is what is so good about Ryan & Sophie.
(ryan) Thanks for the great comment Steven
Another issue with lead acid batteries is that it takes a great deal of energy to charge them from 80% to 100% Dash in addition to the fact that you can’t Push or pull as many amps as you can with lithium. When I was cruising I had 800 amp hours of 12 V AGM batteries and I had a 3 1/2 kVA genset and I never ever bothered to charge the batteries up to 100%. So I really had 800 amp hours and I could only use 80% down to 50% so we’re talking about a useful 240 amp hours. If you’re selling with an auto pilot in difficult weather you can need to charge every day.
The videos are getting much better each week! Really good the idea of the using the color notes, it was really clear!
The best vlogg on explaining the difference in batteries I have seen. Thanks Ryan - looking forward to the installation video
The best explanation I've heard on this matter. Thanks for the clarification.
Another GREAT tech video! Thanks so much for posting this content!
Brilliant, well presented video. Thank you Ryan
very well explained... Nice graphics and editing - thanks for that!
Really great video. Well done Ryan. Thanks for that to both 😊
WOW - This was by far THE best explanation on lithium vs lead acid batteries I've ever seen!
I've watched quite of few of these vids on replacing lead acid with lithium. We will have to do this before we leave for the South Pacific, so we're like a sponge when it comes to information on this. Thanks for this vid!
Thanks for sharing that information Ryan, very interesting.
Agree for full time live aboard Lithium is the way to go. Several of my sailing colleagues have installed Lithium but made the mistake of not having a BMS not having compatible battery regulators for their battery chargers, alternator and solar panels, as well as using the lithium across the full 95% range. Destroyed the batteries and were a costly exercise. After retrofitting these items they now take a more conservative approach and run no lower than 20% and no higher than 90%. Great outcome and the benefits of Lithium are amazing. We get 4 to 6 years from our lead acid batteries which equates to about $200/ year, which is consistent with the numbers you state. Looking forward to the cost of Lithium dropping to the point where we can justify the change over. If we moved aboard fulltime away from shore power the numbers would stack up quicker.
(ryan) I think everyone is looking forward to the cost coming down and it will happen, in a few more years I think you will see massive reductions.
Very interesting. The best information on the batteries. Thank You.
Awesome info! Thanks!
Dude these videos are so informative and understandable!! Thanks alot
Great job of explaining everything Ryan!!
Very well explained. Thank you.
Brilliant presentation . Even I can understand now . Thank you
nice explanation of the "price per usable watt-hour" :) Now I can link to this instead of grinding through it every time. Thanks!
Very clear and concise. Thanks Ryan ... looking forward to the next video. 👍🏻
Hi guys, I just started binge watching your channel a few days ago, your very entertaining and fun, love you’re channel, well done. Ryan, just wanted to say this specific episode was fantastic, really well done , easy to follow and great information. I’m not a sailor but just installed a solar system and had never had lithium batteries explained better. Well done! Can wait to continue watching your adventures.
Great video I'm an heavy industrial electrician and I enjoyed your explanation thanks
Very well explained. Thank you
Great explanation, you speak with conviction and present a solid background. Most importantly to me I learned a lot about several types of batteries.
Very well done, tons of great info.
Super excellent vid , very informative and clever!
Incredible timing!! I just got off the phone discussing a 7000$ conversion including 3 solar panels and a wind turbine. I will compare Dakota. Outstanding presentation, TY!
Ryan thank You. You explained everything very clear way. Thanks for that!
Great job, Ryan. Thanks.
I rarely comment on anyone's videos. Been following and enjoying yours for over a year. I have seen several videos no batteries that lelf me confused. The way you explained and broke everything was excellent.
Thanks Brian! Glad you appreciated it :) next week, we will publish the video about the installation!
Great video Ryan, thanks for the info,
Ryans tech corners are awesome!!!!
this was an excellent episode. I am sure many followers enjoyed the information you provided in it......cheers to you guys! Stay safe everyone.
Looking forward to the install!
Nicely done.
Great explanation on these types of batteries. I’ve been enlightened. 😊.
You definitely made it easy to understand. Thanks.
Thanks a lot for this excellent episode!
This is super informative, thank you so much Ryan (& Sophie), I'm jumping straight into the lithium battery installation!
Excellent explanation! Loved the post-it notes 🙂Thankyou Ryan! -Terysa
Thanks guys! Glad you liked it!
Excellent explanation, looking forward to the install video 👍
Great explanation and video!
Excellent video. Very informative and educational without TMI. Well presented. Thanks Ryan, exactly what I was looking for.
Excellent demo !
This was very educational thank you
Another stellar ryanandsophie video production. Absolutely clear exposition in the benefits of lithium batteries, which, if I ever win the lottery, I will install when I buy my next yacht. Promise.
Thanks for the video
I am looking forward to the full installation video. Thanks
Very interesting and well presented.
Many thanks! Ryan
Great video thank you! That was by far the best explanation on the subject that I have ever heard!
Excellent... great info
Great video on the subject!
Thanks Dana. Ryan
Thanks guys, makes so much sense.
Excellent explanation Ryan, your good at it and you obviously know yur stuff. Thank you.
I appreciate your simple thorough explanations which are easily understood by any layman. Thank you.
Excellent !!!
I'll be waiting eagerly for next video
Best explanation I’ve heard. Enjoyed meeting you in Des Moines.
Thanks Joe! It was so nice meeting you :) thanks for coming all the way! /Sophie
Super bien fait Ryan 👍👍👍 very well explained and very informative. Looking forward to your installation. From being camera shy to being a real pro. Bravo m’sieur. Thanks and best from HKG 🇭🇰
Very informative and interesting video. Ryan you would've been an excellent teacher.
Thanks for sharing:-)
This is a great video, great explanation Ryan...
Great Video!!!! I have watched a ton for both RV's and Boats and you made things I already understood, so much easier to those just beginning their research(awesome price comparison). It was the best presentation and understandable one I've seen:) Enjoy Hawaii, we go every year. What Island? I have been fortunate enough to have been on every beach on every island that you can drive to. I had the pleasure of photographing them all for a website:) Can't wait for the installation video.
Nice job!
Thx for an intelligent info on bats
Thanks a lot Ryan for this tuto even if i discoverd it vert late 😀
Nice :). I did solar power systems engineering about 10 years ago. Seems like it's really getting streamlined these days. Thanx for the vids and try to keep warm out there this week!!
Great Video
Cool video, thanks for going into detail about the battery chemistry, I never heard a lot of that stuff before.
Great video.Ryan !
Best lithium battery video on the internet!!
Well done.
Great job. Looking forward to seeing the next phase. Also, really like seeing the dynamic differences between the Sophie Show, the Ryan Show, and the Sophie & Ryan Show. The mix is Grrreat. Sorry, I use references that no one remembers. But, Tony the Tiger still has a cherished place in my heart, as do both of you.
Ryan, thank you very much. I have always had a hunch that Lithium batteries are more cost effective than lead batteries. Congratulations on your explanations which even me as an amateur could understand very clearly. Awesome.
Well done Ryan.....U are obviously in Ur own element....
Great information, The Work Out Battery 😂😂😂 Thank you Ryan for all the information 👍
I am planning an uninterruptable power supply replacement in the house. Your timing is excellent.
Really good video about battery basics on a sail boat 👍🏻
And nice video trick on correcting led -> lead 😃
(ryan) good eyes! and thanks!
Thanks!
After getting this far into these videos (watching every single one in order), it was rather apparent that Ryan is a genius, but this... this puts him into the category of mad genius!!!
d3w4n3...Your comment is much appropriated! Though i can assure you i am not a Genius. - Ryan
Thanks Ryan. Wish we had lithium back when I did marine electronics. And lead acid batteries off gas hydrogen so ventillation was an issue too.
I'm thinking about upgrading to Dakota Lithium batteries from AGM on my Catalina 25 sail boat. I've been reading about the benefits on the Dakota Lithium website and the prospects of lithium over traditional look amazing. Awesome video! Thanks for the great explanation!
Thats awesome. Ryan
Love it
Thank you
I'm a nerd and I loved the knowledge drop in this video!
Outstanding video. Thank you . ( Sophie will be so jealous of your new video skills)
A few critical instruments (NavCom, CPlotter, AIS, LED cabin lights, etc), as well as separate engine starter cct, could reasonably mandate dedicated electrical storage. But it doesn't require all that much power. The amount of weight and volume for a couple of Pb-acid batteries to support that is relatively low. The delta in wt or vol between a Pb-acid or LiFEPO4 house battery for those purposes is too small to justify the price tag for such limited capacity. In particular, there is no need for the extensive battery farms which have become faddish on boats & vans to power everything imaginable with 12 or 24 volts. It will continue to be much better to store large amounts of energy for propulsion, heating or high-output motors as combustible chemistry and use that to fuel a generator/engine as needed.
But as you know, the battery is not just an energy storage device. It's also used to translate different input formats, frequencies, power levels into a common form, which then again is re-converted as needed. However it's a pretty clumsy, heavy, and expensive way to do that translation. In most modern, current power generators 3-phase AC power is rectified/smoothed to a DC bus, then immediately inverted to some other required form, usually 1-phase. That DC bus is vastly more efficient than a chemical battery; as is flip-flopping format from electrical to chemical and back. The infrastructure to handle 12 or 24 volt DC with the amperage needed to do any kind of substantial work is also massive, heavy, and prone to corrosion and failure; such as 12-volt wiring for 300 amps over a 100-foot run from stem to stern on a small yacht, or multi-horsepower DC motors. Eliminating that 12-volt DC infrastructure altogether will save much more weight, trouble, and potentially cost than any conversion of Pb-acid to lithium.
Although the constant and immediate availability of a small amount of battery power for radios or other small electronics is a good thing, the endless extension of what was really a 12-volt starter motor cct for all sorts of uses is ridiculous. (Even a starter cct is not absolutely necessary for a diesel; it is very common to use compressed air to crank over large industrial diesels, and real-time magnetos were all that were used on early small aircraft - not batteries.) What I'd like to see is greatly increased use of power electronics and rebalanced 3-phase power circuits and motors at approx 460 volts on new small boats and retrofits. Particularly for induction motors on winches, capstans, pumps, and domestic appliances such as stoves, ovens, washing machines; even welders to repair steel hulls, and hand tools such as drills. Connected by a small number of 3-phase busses and sourced by 'instant-on' 3-phase to 3-phase generators and crossover capacitor banks.
My takeaway was that even matching the same volt + amp configuration of their current battery bank would make financial sense over a period of a few years based on longevity. That is excluding the weight/space reduction.
On my list of to do’s on my Leopard before full time cruising next year . I currently run 660 amp hours of gels and 600 amps hours of lithium will be a good swap
Great informations. I agree, lithium batteries are the best choice. We changed the AGM agains the MLI from Mastervolt last year.
I spent quite a few years in the forklift industry explaining batteries to customers and I wish we had lithium back then. Your presentation is perfect, concise, clear and animated . Bravo!! I am fascinated to find out how that marries up with the solar panel power generation process . Clearly a lot of people are solar panel ignorant, myself for example, and the ins and outs of the set up with the new batteries on Polar Seal. Meantime it's 20 below zero here and I have to start the old car while the lead battery is still alive at 4am. Fair Winds
(friarfox) are you still in the forklift industry? Thanks for the comments and feedback.
@@RyanSophieSailing Sorry no, that was back in the 90s in Quebec. I am retired in Indiana now. The business hasn't changed though.Shoot me an email if you have questions, or ask away here. Look forward to your installation . Thanks for sharing.
The best video I have seen on the battery's, very useful information in layman's terms. I feel I know you a little more Ryan, thanks, very good presentation.
(ryan) thanks Randy!
Ryan....FINALLY a comprehensive video explaining all the aspects of lead acid verses Lithium. I have seen a handful of vids on this subject but most of them were really weak with their analysis. KUDOS! Job well done! I'm very much looking froward to your install vid. PEACE OUT! Ü ps, If I was there, I'd lift that bad boy for you! HA!
(ryan) thanks for the great support!
Seriously sir, your should do more videos. You are and excellent presenter, teacher. Meat and potatoes, is what I'm looking for, thankyou!
Thanks! your words are kind. There will be more technical videos and others as the year goes on as well as a book... if i can ever finish it. -Ryan
Ryan and Sophie nicely done. A very clear and well put together presentation. Can I ask that once you have had the batteries in place for a while. That you follow up with a video on charging systems ( for example does your solar cope with all of the boats charging needs, or do you top-up from shore-power or engine power if yes how often is that necessary), average charging times to get back to 100% full during different times of year, and any maintenance you've had to do to keep this new system in tip top shape including any component failures with your new setup. Thanks and travel safe, Duncan
Hello! Absolutely... this is in our planning! - Ryan
wow.. I think you found your sea legs... I think you need to do more of these on systems... well done sir, well done...
Thank you for a great video! I am usually in favor of buying the most long-lasting and durable goods I can afford. There's always the question of how long the product will last and the more expensive the product the more important it is it lasts a long time. What is the warranty on most lithium ion batteries for boats?
Good clear and personable presentation. I understand your unwillingness to be on camera (I hate it too) but you appear surprisingly comfortable.
