As a retired PE, Oliver, you are outstanding. Where did you get the PowerBMS? I keep coming up with nothing on google. How about today, 2021, using 200 AH cells and running the bank at 50 V so that you can charge at 200 A from your alternator? You could dump the 50 V to a 27 V unit which is always charged by the 50 V system. The 25 V battery could be 300 AH. You can feed your inverter from the 50 V bank to 240 v Inverter as required. Yes, it would give you double the storage and when you jump from location to location with the diesel, you can charge the big bank. I am looking at 400 w SPs with 4 on the stern and 2 on the side rails. Great job. These are the best batteries with the best battery clamping system to resist battery swelling and extend the battery life.
Thank´s Grahm, we are fine on board. Our last port was Gran Canaria last december, since then we crossed the Atlantic and sailed the West Indies. Living all the time on anchor. No Marinas. -Oliver-
Thanks for the useful description and the crystal explanation of a boat system. This is what we are looking for on an Amel SV, beside you both are quiet cut! Be safe and keep us update, Love! :-)
Hello, yes this lithium project is a bit different from all other implementations. By now we where successfull and do apply this proven system on other boats. Its not a small project but it was worth it. It´s a real game changer and made life on board so much more easy and comfortable. Now we are 2 years living on this batterie and our installation and no problems. One of the advantages is that we have one single batterie and not a stack of small units pluged together. There is more infos at our website www.velanautica.org so long -Oliver-
I do not know how I found your channel (but I do follow lots of sailing and boat build/refit videos) and I am glad I did. I realise this is just one video of your installation (I will watch the other shortly). Just a couple of questions: 1. Would there have been merit in rigging the best of your lead acids as the engine/generator start accumulator and possibly a couple forward for winch and bow thruster? Or just too complex with respect to cabling and charging? 2. How have you designed for temp regulation of the batteries especially the issue - if too cold notable to charge)? I watched your freezer rebuild - absolute master class.👍
Hello Norman, On our boat it was not nessecary to rig any batteries to the bow for windlasses or bow thruster (10Hp). The lithium batterie can easy handle these units even without engine support. I would anyway not like to have any batteries in the bow, if there is no separate charger for them, they die quicklybecause they never get full charge because of the long wires. The temperature regulation for the lithium batterie is handled by the powerBMS desing, it monitors the batterie temperature and in case its too low it will prevent charging. It could even start an electric heater to warm the batterie in to charging conditions. so long -Oliver-
Great implementation! I noticed that you promised to provide a link to the battery supplier but haven’t found that link. Could you also provide a link for the BMS please? Thanks Be safe.
Hi there, trying to find more info on which cells you bought and about your BMS. After three months lockdown in Busuanga I am just on my way to Cebu(Carmen) to use the rainy season to install my LiPo's and a water maker and a rigid dodger on my boat. I am going for 400Ah LiPo (small boat, only 31 ft) to replace my 200 Ah old Gel house bank. Would love to hear about which cells you used(make/model/I'll have to ship to PH) and about the PowerBMS (is that a Kit ?). Cheerio and beste Gruesse
@@svvelanautica2374 Hi there, thanks for getting back to me. I don't have an email for you so I can't email you. I have 400Ah of Winston LiFeYpO4 coming (8 * 200 Ah in 2P4S) and a REC-BMS which ties in and communicates with my Wakespeed 500 3-stage Alternator. Still in Carmen, PH working ont eh boat and feeding mosquitoes. All the best to you. Are you sitting out Hurricane season in the Caribbean ?
@@novelistusonthewater Oh, you are good setup, Winston will be fine cells. We got the free version of the wakespeed. Do not place the lithium cells in the engine room. better find a well tempered dry space under a bench. Its worth to reroute the wires if needed. Yes, the first hurricane of this season is closing up, aproaching on Saturday morning. Tomorrow we move into a Hurricane hole and sit it out. If we are luck izt will stay south of us and if we are very luck it will diminish... hope the best. -Oliver-
@@svvelanautica2374 OK, I keep my fingers crossed for you in regards of Hurricanes. Well, I was too late for AltReg project. There wasn't any boards anymore and Al had already partnered with Wakespeed. I bought a better Alternator (110 A instead of 60 A). Lots of connected projects right now. The LiPo's, BMS connected to Wakespeed, Watermaker (based on Karcher K2) ran on LiPo, hard dodger, more solar. Do you know what happened to the control SW they planned to offer for the AltReg ? Amel 54, lucky folks ! Thats always been one of my dream boats but out of my range. But I'm really happy with my little 31 Hallberg Rassy. She's been a great boat for 20,000 nm+ so far and most of the time I sail on my own anyhow. Greetings from PH
Hello, you will get my answer soon, I will get a direct link to the right product from the vendor. Please watch our future videos about the technic to build this kind of batterie. there are some pitfalls about neede cellbalancing equipment, BMS, cell connector setup aso. I will describe all this soon in part 2 about this project.
I think thats a good size for this boat, we have plenty of spare energy. There is times on a boat where u need it, like when the genset gets its maintenance. We can also run our watermaker on the batterie for hours producing, 100 liters per hour, The Watermaker does not take so much power and the genset would idle a lot. Now we run the watermaker 3 hours and recharge in less than 1 hour. On passage it turned out that electric cooking was favorite. We cant open the hatches on passagre because the waves might give us a salty shower into the boat. When you light the gaz cooker in these conditions the oxygene in the pantry is quickly gone and you breath gaz fumes. That was over and we could enjoy electric cooking while we had our Atlantic crossing from Gran Canaria to the Caribbean. Since we left Gran Canaria in December 2019 we did´t need to go in a marina, since then we live on anchor including the Atlantic crossing in January. Now its July 2020, so more than 6 month now. -Oliver-

So nice to see other parts of the world and also to see a Filipina being able to explore so many places too! Congratulations
I love you two. Stay safe fellow travelers.

Good one, very interesting, thanks you.
So many lithium options out there. This one is a little different and I think this is more along the lines of what I want to use

@@svvelanautica2374 I would be interested to know which lithium batteries you purchased as well
Hello. Now this battery cost 300+ $... but it really cool decision. What about bms. A can't find. Which model was it.
Hi nice Video, would you mind sharing where exactly you had ordered the batteries? I would very much appreciate it. Maybe you have a link?

@@svvelanautica2374 Great thank you very much, I am looking forward to the next episode and the link :-)
I’ve heard that Chinese batteries are not as good as others. Don’t know in what way. Perhaps the BMS.
14kWh of lithium battery storage. That’s huge.

Charge times to 100% are much better over Pb
oh china
Background music is annoying
Hello, this is one of our more early videos, we changed now to a professional soundtrack provider. Music should be better by now.
