Tesla Lithium battery question.

[DeepFrz]

Has anyone on the forum installed Tesla batteries on their boat? I know these are not LFP but they seem to be very safe batteries and I was wondering how people handled the different voltage.

not safe to install on a boat due to thermal runaway potential.
Tesla uses Lipo not lifepo4

Yes not safe away from its thermal safety systems and central controls.

Backyard shed science project, not for a boat.

[DeepFrz]

Yes, thank you. Has or is anyone using them on their boat?

[transmitterdan]

Unlikely since they are liquid cooled. There is not much special about Tesla batteries except the packaging. The underlying batteries are fairly old tech. The bms system is not in the pack so would also need the processor from the car.

Probably cannot get insurance for a boat with Tesla batteries. So unlikely very many will want to brag publicly about it even if they were stupid enough to install them. Then again we should not underestimate the level of stupid in the world.

if you decide to give it a try let us know .
Also let us know where you are so we can watch the papers for a battery caused marina fire.

This is the kind of question where the answer is: if someone hands you a brand new (or lesser) Tesla bank, the best and cheapest way to install it would be to sell the Tesla bank and buy/DIY Winston/Calb batteries with your cash from the Tesla sale.

You can always figure out a way to get a square peg through a round hole, but if it's easier and cheaper to just swap for a round peg, I'd take the swap option.

Tesla banks are made from the extremely common and widely available Panasonic 18650 cells, that have been the go to cell for home brew designs for years.
They are a good, quality Cell and the risk is minimal, but existent, usually what sets a Lipo battery off is physical damage or extreme overcharging.
How many Tesla’s are there on the road and how often does one catch fire?
You can do it, but why?

[john61ct]

They don't (often) catch fire because of the car's complex protective systems surrounding them.

There are EV guys working on reverse engineering the BMS etc functionality.

Great hobbyist projects, just not ready for us mere mortals to sit on in our boats.

This was my cave diving scooter

A kilowatt / hour small, light weight battery, not much larger than a big coffee can.
Very safe, never heard of a failure.

However the original question stands, why?

[john61ct]

Sometimes they do come up cheap.

Or doing so sounds cool. Cooler than Leaf or Volt anyway 8-)

[DeepFrz]

I was just wondering. I saw a guy installing them in his RV and wondered if anyone on CF was doing it.

On Sailing Uma, a Pearson 36?, (see YouTube), Dan removed a diesel and installed an electric motor for the drive system. Recently, he replaced his lead acid batteries with commercially manufactured Lithium Ion, and it appears to be a successful first. Since this only took place about a month ago, he is not finished testing or reporting on his progress.


He did not go into the construction or specifications of the batteries, but I believe they are made from collections of 18650 Li batteries, just as the only larger Tesla banks are.


There is a future in boating, combined with solar, for this technology.

Just to clarify.. Sailing Uma did not install Lithium Ion batteries.. They installed LiFePO4. They installed BB10012 Battle Born 100Ah LiFePO4 batteries.
