Don't the Tesla packs use lion chemistry, and wouldn't LiFePo4 be much safer and durable in the long term?

I like your video！ keep doing it！

Nice work!

13:09 I died

I found the video to be great - any comments now, 3 years into its use how it's working. All good or any comments you'd like to add?

How does this system cool? Is there a separate system I’m missing?

Good morning I have a dps 800gb-2A. Compared to this one in the video is there a difference in making the transformation? Thanks

Man, Thanks, so interesting. Amazing job was done. Would like to hear feedback after few years, how it system feeling still running, any isue to improve or all perfect since beginning

How do you get such a low frame rate it's painfully to watch Also you connected the packs wrong, you need to cross connect the positive and negative wires. Although with these low currents it's not that big of a deal. I'm scared these will once get into thermal runaway and burn down your house. Man, buy lifepo4, they also last way longer and match better in voltage with your inverter

You have 2835W of solar for charging. How much power do they generate in a typical day?

I will suggest adding a couple of AFO balls in the DB case, in case the things go south. Neat work though 🙌

You should put an insulator material between each module, Just for extra safety

This answers my question about using Tesla batteries for a battery bank

Just curious , why wouldn’t those still need to be cooled?

im wondering why not use the battery as it is. is there something wrong with the battery? it would seem to be much easier and very very much safer to just use the current external connections.

Suuuper nachhaltig diese Bauweise. Das ist richtiger Umweltschutz...

Interesting video, what is the BMS u are using?

This should be enclosed in a metal cabinet!

This is incredibly irresponsible. All it takes is an internal short within a cell and your house is gone. You could do everything perfectly and still experience a thermal runaway event. During a thermal event, the hot gasses of a cell will directly shoot into another module grid. You have zero thermal runaway protection For those watching on RUclips, please don’t replicate this. Leave this to professional engineers

Nice music, annoying as fk

Can I have afew of the battery to build an small ebike cell?

Do you need a resistor? I know on the DPS1200’s you need a resistor or they will blow up after a few weeks.

- Лёлик, но это же неэстетично… - Зато дёшево, надёжно и практично! Осталось найти регулировку напряжения. Но это уже опытным путём. Берём резистор на 5-10 килоом. И сединяем через него плюс последовательно с сигнальными котактами. Следим за вольтметром. Если есть колебание то мы нашли либо регулятор ибо 12v share/ Меняем номинал резистора на другой большой и проверяем снова.

You have any 21700 cells? I'm looking to buy some

Your job is impressive. thank you for interesting video

A lot of "hey. hold my beer" engineering going on there......

Do not use a parallel connection on one side of the cells. Give the plus wire on one side and the minus wire on the opposite side. This helps to unevenly discharge and charge individual cells.

Is it possible to use the battery pack “as is” directly. Would seem a lot safer and easier. Is voltage a problem?

Solid setup

We gonna need to double up on da power. I need more battrees

Nice clear video Zai thankyou. I also have a 3 kVA Multiplus and MPPT charge controller to set up , Can i ask what settings you used to interface with those battery modules so they partied nicely together ?

Wrong main lead connection! The + and - lead to the inverter should be connected diagonal to the first resp. last battery in the pack, so you have no voltage/SoC/performance difference between the batteries.

Why did you use mppt controller? Because victron 24V 3000 inverter does not have inside it? Or do you have another reason for that?

Rather use LiFePo (LFP) less hazardous than Li-ion. Less energy dense. Less risks.

Why did you not only change the bms's?

I skipped through video may I ask what you use to actually charge batterys please and what amps to charge and voltage.

Absolutely love watching young people making a serious effort, using affordable parts but doing a good job. Well done there :) If only the older (my) generations were making as much of an effort.

Thats a bad ass setup! Twelve 250a 24v modules! WOW! Im currently building a Tesla system, currently have 4 of the modules and want 4 more.

This is a nice setup you got going on there. Would it be possible to use the battery pack in it's original state, aka without removing the modules, and do something similar to power a mobile home/trailer/caravan? Asking because I do live in a could country (-20C, -25C). So coolant for keeping it warm in winter and cold in summer would be nice.

Heat guys , heat. Take a heatgun to loosen the kit.

This was like teenagers having sex for the first time. A real cluster fu€k.

Genuine question, why do all this? What do you get by using a vehicle-grade battery pack for a home? You get more capacity. But it is meant for a vehicle type environment, to withstand different conditions, which you won't be facing in your home. So all that is really just an overhead that you're throwing away.

Thanks

Hey Zia, Awesome build. ❤ Love it. I live south of La Paz Mexico. In 2015, 9 years ago, I built our home out in the desert. No grid available. I bought 22 used Tesla batteries from demolished Smart cars. These are 54V nominal lithium batteries made by Tesla. At the time each used battery cost me $1,000 USD. I connected all 22 batteries with a machined bus bar and used NO BMS. I have been running my house that has multiple 2 ton air conditioners since 2015 with no problem. My QUESTION to you is if you used no BMS how much cheaper would your system be? I’m selling my Mexican house in moving back to the states so I will need to rebuild my system in the USA for my new house. I very much like your system. Much love from Mexico ❤. Also have no fear of heat for you batteries it gets really hot where I live and I am on top of a volcano vent. Your home will never get hot enough to cause a problem for the batteries unless the house burns down first. For inverter and MPPT I am using a Schneider 6848 and 200/80 MPPT.

Nice work.. I started my power wall about 5 years ago using mostly Lap top cells, Now nearly all are gone.. don't be tempted to use laptop cells, they are discarded for a reason. I'm up to about 20Kw but that's where it stops as the solar shed is full. Its my Daily top up for my Tesla.

So how did you get a Tesla battery pack for only $4800?!

Loving your content. How’s the hydrogen generator coming along? Hope to get some updates from you 😇

I can't stand the choppy framerate in some of the shots

Great idea putting a battery pack into a nice wooden box! It will aid in accelerated combustion when the whole project goes up in smoke.

So when you wire tesla packs like this they are basically dumb packs? I don't see how a BMS could balance the mods in a setup like this? You basically just flood the posts with current and push the front cells hard enough that the rear cells eventually reach 100% SOC? I just don't think this is a good long term solution
