Boat Problems with Lithium Batteries | Electrical Design | Sailboat Trawler Restoration (Ep107)

[@trep53]

Hi Joe, I give this ⭐️⭐️⭐️⭐️⭐️ on the boat work video list. I’m sure there is a lot more to it so I’m staying tuned in to hear more. This project is big enough to warrant help from outside experts and once completed can be scaled up or down for future projects.

[@motorcityboatwerks]

Thank you so much for your comment😁👍 I love it when folks get what I’m trying to do with MotorCity Boat Werks. 😎 Thanks again to all supporters and fans 🥰

[@MVSheKon]

Paying very close attention Joe. Keep it rolling hot in the New Year! Cheers! Rick

[@motorcityboatwerks]

Thank you Rick! Stay motivated my friend !😁👍

[@Cptnbond]

A great episode with loads of valuable insights. Thanks for sharing. Cheers.

[@motorcityboatwerks]

Thank you for your comments CaptainBond 😁👍

[@907T]

Well done Joe.

[@motorcityboatwerks]

Thank you! Happy holidays Joe 🎅🎄

Hi Joe. I want to say Marry Christmas and Happy New year to you and .... Tchan ... I bought a Bruce Robert motorboat 43ft .. I am very excited with some cosmetics projects. Be happy dear friend. I am from Canoas City, Brazil

[@motorcityboatwerks]

Merry Christmas Jeferson. 😁🎄Good luck on your boat restoration

Very sound advice, in the words of Dirty Harry, “A man’s gotta understand his limitations”

[@motorcityboatwerks]

Exactly 👍

[@MPrybil]

In the movie “Cool Hand Luke” two great lines: ‘a man’s gotta know his limitations’ and ‘ what we have here is a failure to communicate!’.

Although I understand your desire to keep with one charging and regulating system, you may want to consider a split system using the older technology exclusively for the engine system and the lithium for all your other electrical needs. By the way, you can install more than one alternator on that engine. Happy New Year to you and your family 🎉.

[@motorcityboatwerks]

Very true Barry, I’m thinking this may well be the ultimate solution. 🤓But the series 6 is a single foot mount and both alternators would need dual mounts on the Beta 43 engine 😕

[@bblod4896]

@motorcityboatwerks There may be a solution. 😎

[@motorcityboatwerks]

👍

Okay, there is one nuance you may be off base here. Please talk to your consultant about this. 12v is fine and all that, BUT if you spec 24v or 48v, you’ll save a great deal of money in wiring and components, then finally convert to 12v for the appliances running electrical. It would be interesting if you did a follow-up on this explaining the cost savings. I think 48v might be close to half your total project cost.

[@motorcityboatwerks]

Thanks for the comment. On the surface this might seem plausible, there are advantages to 24v or 28v. But the availability and selection makes this is not the case. 🙁

Joe- you're reading too much into the abyc standard. I'm actually studying to get my ABYC electrical cert. You are fine with having the fuel fill and vent running along side the batteries. Just can't have batteries laying directly on top- or below- a fuel tank without a deck partition. So no need to re-route your fuel fill and vent

[@motorcityboatwerks]

Thanks Danny. But the specific rule is quite clear. Fuel fill and vent constitute fittings -and the batteries can’t be below them. So the fittings must be moved. Then uninterrupted fuel lines can come back through the electrical compartment 😀👍

Lifepo4 is the only way to go nowadays. Half the weight twice the power and 10x the lifespan. Start battery should be the only AGM that you buy anymore. Alternator charging lithium is not hard you can add dc to dc charger or regulator for alternator. If you have an alternator that can produce 100amp you don’t need anything as most bms on lithium will only charge at 100amps. Currently on my boat I’ve got lifepo4 and I parallel connect them to AGM and charge from alternator had this setup 5yrs now. Currently I’m designing a 50amp 240v split phase setup and I’m going with Victron. 120amp alternator will work on lithium read battery and it will say it only accepts 100amps to charge.

[@motorcityboatwerks]

Thanks for the great comment 😁👍

[@seanmccambridge]

Just to be sure it’s clear, LiFePO4 is lithium iron phosphate, not lithium “ion” phosphate. 😎 Lithium ion (Li-ion) batteries should be nowhere near a boat.

[@motorcityboatwerks]

You are correct Sean Thanks 👍👍If you have been watching my channel you know each episode I intentionally make mistakes so uber-observant viewers like yourself can demonstrate their advanced abilities. 🐙😀 This week you are the most-best-observant-viewer! Definitely don’t want to blow yourself up 🤓

[@seanmccambridge]

Wow, okay. Hope I didn’t hurt your feelings. Just trying to keep people from getting the wrong (potentially dangerous) information. Very thorough and well produced video. Good luck with your build.

[@motorcityboatwerks]

No offense taken Sean 👍 You’re doing and excellent Job 😁Thanks for the comment

[@LouisBackover]

Came here to say this!

[@motorcityboatwerks]

Thanks Louis- you get a gold star also ⭐️!

Run a 40 AMPDC TO DC CHARGER OFF YOUR 12V SYSTEM TO CHARGE BATTETY BANK

[@motorcityboatwerks]

Ok
