@@drumswest5035 They are as heavy as 3 adults, our fuel tanks have 3 times more weight variation based on how full or empty it is. So no, but we had more heavy furniture on the other side of the boat, so it kinda balanced the weight a bit.
Great way to recycle EV batteries. Curious to know what % charge capacity is still in them. Good work. You really need to build an enclosure around the batteries though, they would create a significant risk if they move in a rough sea. One last thought, you can buy these balls that are fire extinguishing balls. They explode if they sense flames. They are cheap, and although i don't know how well they work, I fitted them in power rooms where I put inverters and big battery banks. It's worth considering. Again, great video, and well done guys.
It is about 20kW left out of 24kW when they were new. The battery will not move because it is bolted down to the floor. The top case is in plan but will be more an aesthetic thing rather then will do anything for the battery. If lithium batteries start to burn you are not going to extinguish them with any balls size 🤣 You just have to get out of that boat and that’s it. If the battery is not overloaded, have good monitoring system and nicely engineered there is nothing to be worried about.
No I did change the assembly to make it compatible with our inverter. Now it is 12s16p 50.4V. Ideally to use 13s or even 14s but 13s is almost impossible to assemble due to form factor of the Nissan Leaf batteries cells and for 14s I would need extra cells. So 12s is just the most ideal option for current setup
Lifepo4 is cheap now but I'm almost 100% sure it isn't safer than the Nissan leaf battery. I destroyed modules from a faulty balancing circuit and all it did was pop and vent. No flames at all.
@@YachtCityLife you can get brand new lifepo4 batteries for only $90/kwh(about $100/kwh shipped). But I still like the voltage curve on the Nissan leaf cells a lot better. I can always look at the pack voltage and know almost exactly where the battery is sitting. No columb counting that drifts and has to correct itself time to time. That always comes back to bite lifepo4 users.
The IC (interrupt current) rating of the circuit breaker is much too low for this battery bank. You need something like a T-class fuse preferably as close to the battery as possible.
The IC rating for the circuit breaker will be listed in the specifications. If the IC rating is too low in the event of a short circuit there is a risk that the circuit breaker contacts will fuse and prevent the breaker from interrupting the current. Because lithium batteries can deliver a high current the circuit protection requires a high IC rating. Typically 20KA is required even for a relatively small lithium bank. The pictured circuit breaker will have a much lower IC rating than this. This is why expensive class T fuses are usually used on marine lithium banks.
Please have a safety exit plan to get off the boat in the event there is a runaway fire…it can happen in an instant and no amount of water or fire extinguisher will put it out! There was a resent incident where a couple was found deceased from exposure on an island off the east coat of Canada… They apparently had left their sailboat in a hurry. I had just started to follow them on TH-cam and they had converted to electric instead of diesel and had used a Nissan Leaf battery for their battery electrical storage… Their sailboat has not been found
Hello! Thanks a lot for this new interesting video! Waiting for a new one 🙂
More to come! Thanks for watching 😜
Amazing job! Congratulations!
@@MrJerobona thank you!
Brilliant? Looking forward to the next video. Marc from Bremen / Germany
BRILLIANT!!!!!!!
@@marcdodenhof1339 thank you Marc! More is coming ☺️
cool setup
@@destinny29 thanks!
Well done👍
@@JrR-fw5ph thank you!
Love this channel 🎉🎉🎉🎉
@@David_Blong thank you David 🔥 happy to have you here ☺️
Did you calculate the weight and balance of the batteries for the boat?

Hi, did you keep the original voltage or did you decide on another assembly to obtain a voltage that suits you better?
No I did change the assembly to make it compatible with our inverter. Now it is 12s16p 50.4V.

Nissan leaf batteries. Nice.
That's a nice and compact battery for 20kwh. What is the cost compared to getting 4 of the 5kwh server rack batteries?
2000cad
Lifepo4 is a safer choice for a boat...
@@cbinett and 5 times more expensive 🫰🏻

Not as cheap as Nissan Leaf batteries. 20kWh (originally 24kWh) cost only $2k CAD

It does sound like a scam. Can you send a link? The cheapest LiFePo4 I found is about 300CAD per kWh without shipping

@@kirbythomas5468 makes sense 🔥
You may want to switch to a safer battery chemistry as soon as you can afford it
@@kirbythomas5468 yeah, this is the plan. The more subscribers we have, the faster we can afford it haha)
