Wow that was a fast reply. Many many thanks for the info and your fabulous work.
please do a bms video for these cells. That would be awesome.
Regarding the BMS for NMC battery, should get one for Li-ion or LiFePO4?
What is the resistance of 2 NTC in the module at room temp ? I need this to see if I can use the internal NTC of the module to connect to the BMS.
This looks great! Can you show the charging circuits and the inverter circuits / hookup?
I see you posted 3 bms in the description i ordered 4 battery and going to run 24v which bms do you recommend
Jehu, I've got an existing Enphase grid tied solar array, 15 kW peak production. On a typical summer day we produce 80-90 kWh. What drives me crazy is that our power company required the system to be tied directly to the grid, we have no direct electrical connection between our solar and our house. To fix this situation we need batteries. I'm looking for an AC coupled battery system that will play nice with the Enphase solar to allow us to be grid-tied 98% of the time and automatically switch over to battery and solar power for the 2% of the time that our grid goes down (which happens 4-6 times per year unfortunately). Batteries like this for $100/kWh are really tempting but of course the key is sourcing the right AC coupled inverter/charger. Do you have a recommendation?
bms is a must on these, are these pouch cells and can be charged to 100% to balance, or a cobalt chemistry? Amazing quick build. 100kwh for $10k.
Im thinking trying this for my first solar project. Whats a good solar panel and charger controller i can get to complete the system?
how much it will cost to ship India
(5 pack).
Good stuff, subscribed.
So what would the price be for a 48 volt system
Love your vids. Always interesting which batteries come up.
I was wondering, is there ever gonna be a diy grid tied powerwall?
yes I have a design in mind
@@jehugarcia can't wait. :)
@@jehugarciaany ideas on how to cope with ‘risk of fire’? Will an insurance company cover a DIY powerwall?
I watch lot your video ❤❤❤❤ i have 48V 3000 watts pure sine wave in i have 48V solar charger controller 30A i have 4 12 volt battery 18A each what size solar panel to how volt or watts solar panel
Hi. Just watched your video. I was just wondering about charging. Could I charge one of these units using a standard car battery charger or even better one of the affordable 100W solar panel and 20A or 30A charge controllers available on ebay. Or does the battery have to be charged using the unique connector you refer too? Many thanks in advance
You can charge it with any equipment you can set the max voltage of 12.6v per module, this excludes most 12v chargers and 12v solar charge Controllers. Variable power Supply is your best bet
Awesome!
Maaaaaan i want some of those
Having access to the cell voltage makes these fantastic. I just don’t trust the balance part of the bms on used packs without being able to verify.
I’m really looking forward to Bluetooth bms batteries hitting the used market.
My biggest concern with Li-Ion in powerwalls is the fact of how volatile they are. Since they are sealed, I'd be very interested in seeing what happens if a module gets shorted till total failure. Also, what if its sittiing in a fire, does it eventually fail catastrophically? Or does either test result in failures being totally contained (ie it wouldn't affect adjacent cells)?
Fires on these are basically unheard of, since power wall batteries are under very low stress, far less stress than EV batteries which are BRUTALLY discharge and charged
@@Ryukachoo Actually ive seen a burned lgchem module, but it was an user error because of no cmu use :D And it burned really little. THere was a video on youtube from Ukrainian user, but can't find it
If you can verify that each individual cell never goes above 4.2v then these are not a fire risk unless they get physically damaged or flooded with salt water.
I regularly check the individual cell voltage plus I only charge to 90% when dealing with used batteries. Making sure they never go over 4.2v
awesome! i have a question...im buying fork lift and wanted replace the old dead lead batteries with litium diy style and add my own ballast, is there any reason why id need special forklift lithium batteries?
cant find any info or get arepsonse.. my sense is its all the same. i think its 850ah 36v lead
Yes you just have to verify the slight voltage difference is not a problem. Then find out the max current the forklift wants and make sure you battery can handle that.
Also never let a lithium cell go above its max voltage. With these it’s 4.2v. But you need to verify that with each cell specifications. Over charging is the number one cause of fires second is physical damage
We are currently running our 36v forklift with one of these modules jag35.com/products/chevy-lg-36v-5-9kwh-li-ion-modules?_pos=2&_sid=294c5f43b&_ss=r
@@jehugarcia nice. How long does that last
@@jehugarcia looks like you don’t ship those. I’m in Nc.
Is this something that could be used with a Bluetti AC200P?
I would like to know this as well.
I can’t wait till i have the money
Looking to do a powerwall, Im currently on your webpage searching.. Can i please ask how these will work on 24v system if they are only 11v?? 2 batteries n series would only be 22v.. Also in video you start to talk about the bms but dont give much info as you switched to talking about the cable connector.. Is the bms in the Phoenix inverter and you jjust need the connector to plug into it?? Sorry for my incompetence, im learning this as i go.. Thanks bro!!
2 in series would be 22.2v. So would only work with some 24v inverters like the referenced Victron ones. Bms, you have to source it yourself, it can be any 6s li-ion units available in the market today
@@jehugarcia Sorry to bother you again, can i please ask what to search for on google or the ali's/amazon?? Tried searching and only thing that came up was in the $400-$500 range.. Thanks for your help!!
I ordered 4 I was expecting to get bus bars as stated In Video I did not receive any. What gives? Did you run out is there a way it get some??
Contact support@jag35.com we should be able to ship them out to you separately
Can you post the hardware you used for stand offs
I got these too and after some experimenting, the corner mounts are 5/16 and over 3 inches in length, that will be up to you. The terminals i found that M6 1 thread works, little tight but nothing is stripping, at least 10-20 mm length works great
How good is NMC compared to Li-on and LFP?
way smaller and lighter, but less cycles
Wouldn't it be best to do 5 of these in series for a 48v power wall?
Yes you can
11.1V nominal @ 5S modules = 55.5V, 63V fully charged
Hi jehu, how can I buy Tesla batteries? Thanks in advance. Btw, I’m from Australia.
eBay
Garcia PM me para ayudarme hacer un PW con esto. Dejame saber precios tampbien. Gracias
👍👍👍
1. Are they new?
2. What's the warranty?
3. Does it have an internal bms with low temp charging shut-off?
4. What's the link for these batteries? I can't find in description.
Thank you.
How many would I need to run my house and not worry about anything?
40kwh
thats not an answerable question
These cells look awesome but can you confirm that they aren't part of the I-Pace battery recall? NHTSA 23V369-3467
Would be very interested to hear Jehu commenting on using recalled batteries in 2nd life applications. For example,, modules have been recalled because of cell impurity issues- debris has gone on the cathode. Do we reuse the modules? What is a nogo recall and what is an ok-lets see?
I can not confirm unfortunately, As far as I know these are from car wrecks, thats why we get 1 or 2 cars worth of them at a time. I said in the video that there was another pallet inbound but it turned out to be completely different packs (Tesla Rav4 Modules)
WARNING: Jaguar Land Rover North America, LLC (Jaguar) is recalling certain 2019-2024 Jaguar I-PACE vehicles. The high-voltage battery may overheat. Consequence: The high-voltage battery overheating increases the risk of a fire. Remedy: The battery energy control module software will be updated by a dealer, or through an over-the-air (OTA) update.
I hope it's not these batteries.
I saw that too but i already bought them. The issue im having is that i can't read all the cells through the connector on some of them. I speculate, with what I'm seeing, maybe the cell connections weren't complete and that was throwing off the bms since not all the cells were in check.
@homdiddlyoh bring a previous buyer from Jehu on several battery types and thousands spent.. I can say that without a doubt, nothing has been top quality. I'm honestly just going to buy new from now on and actually get a warranty and not deal with the hassles. His "great prices" aren't even great with these issues.
Go time
Aloha
@jehu Lot of Australian subscribers.
Anything ???????
gdaymate
Love those but man the cost f this stuff just pushes me out of the race
Battery prices are the cheapest they ever been
you dont know how broke ass i am and still doing it anyway..@@jehugarcia
To build a 48V with these is way more expensive than a EG4 server rack battery. Actually you can get 1 and 1/2 EG 4 battery for the cost of this.
But you need 4 eg batteries to get 20kwh. Eg4 are
Exactly 3x more expensive than these.
im sorry bro but get those aluminum busbars out of here.
The proper spelling is kWh
2 mistakes in the title
How can I trust the content of this video if you are clearly not an engineer?
I don't think he ever claimed to be an engineer. He's a guy who likes batteries and was doing videos about what you can do with batteries when a lot of that information wasn't available at the time. He imports batteries, figures out things you can do with the batteries, and has created a way to get those batteries to people that otherwise wouldn't have access to them. Trust him or don't trust him. No one cares.
How can I trust that you are capable of safely playing with batteries if you cant see that spelling is not the important thing to focus in this video..... pedantic fool
When it comes to engineering spelling is very important 😊
@anonymousmc7727 nope . Spelling is not important to me, specially in English where there’s no rules, just a bunch of exemptions.
