BEST BATTERIES OUT THEIR GET YOURS BEFORE THEY SELL OUT.

Some people sure like to complain about the dumbest things, sure Jehu held the camera and recorded but the ideas he shared were very useful. I ordered four modules and all the cells tested above 3000 most in the 3100 range very close to 3200. I just wish I weren’t so broke I’d order at least 20 of them to do the same thing Jehu is doing.

Great stuff! Enjoy your show. Building my own Powerwall here in South Africa!

Thanks for all the hardwork Jehu 👍

Waiting for you to get it all figured. Promised my sister to make her a 36v pack for her golfcart

It’s great to see your continued interest in building with li-ion batteries. Be it a Volkswagen electric bus or a power wall. The great part about it is the knowledge you share with others. Still keeping safety in mind. Thank you.

Jehu, if you're getting into 3-phase power, you would be wise to have a licensed electrical contractor take a look at your building power system, and advise you as to how to hook up your battery system. 3-phase can be a lot more complex than it first seems, and compared to split-phase. For example there are two basic types of 3-phase, called delta (for the triangle-shaped look on a schematic) and wye (for the Y-shaped look on a schematic), and if you plan on altering the power coming in, you'll need to know which kind you have. Delta is used for long range power transmission because it only requires 3 wires, and also to power large induction motors. Wye is used more to distribute power to offices in large buildings. Both can be used to make split-phase power like a home circuit, but because each leg is 120 degrees out of phase, the voltages don't always add up like they do with single/split phase. Neutral and grounding can be a bit different too. It's fairly easy to make split-phase branch circuits from a 3-phase input, but not so easy to configure inverters to deliver 3-phase power when there are also split-phase legs. A good contractor will be able to figure out how best to convert from what you have to what you want to have at minimum cost and danger. It's money well spent.

Just an observation, take it or leave it. 3-phase is not your strong point either..... Star/Delta is the terms you are looking for and yes, a electrical engineer would be best to design things however, a 3-phase inverter is advised. leave individual single phase systems bastardised together for those with too much time on their hands. Yanks and their bloody "Split-Phase", far out.

LOVE your videos-I am learning SO much from you!!!!

thanks for doing the project with these battery packs, here in SoCal we have too many scooters in the trash, good way to recycle. thank you.

you need an Arduino to turn on the local BMS, not seeing the original wiring and testing the BMS it's kinda hard to reverse engineer. After messing with one unit it looks like a serial connection will be needed. These are GREAT batteries!!!

Awesome work! We need to get access to that BMS somehow.. :)

Cool workshop 🙂👍

thanks for sharing your build! It really change my perception and approach on how to do things properly, with lesser cost and improved build quality ! Just need to figure how to get those packs in europe :)

What about a small shunt trip breaker? Use a depletion mode MOSFET, when the BMS shuts off, the mosfet will conduct, tripping the shunt trip, disconnecting the battery, eBay has tons of shunt trip breakers, I don't use mine as a breaker, it's basically used as a latching relay, I have fuses, and a disconnect in series with the shunt trip breaker, like this you can use a tiny BMS, and balance manually, if needed, you can use a enhancement mode MOSFET, with resistors, and zener diodes, to accomplish the same goal, it's just a bit more complicated, cool system growing there!

They r great cells ive tested a few?pack and not 1 tested below 3000ma.. hope this works..

Looking Sharp!!

That would be called 3 phase 208 volt bro. 😁 love the shop btw. 👍

I have a couple of these batteries with functional BMSs, I want to dig into them maybe see what wires do what on yours? I’m able to charge both with a regular 36v scooter charger, but they will also charge each other when the power wires are connected in parallel.

You are awesome. Thanks for your videos.

If I had a few packs I maybe can get the BMS working. Not going to buy them tho. Have no real need for it. Thanks for sharing looks cool. God Bless

Hey Jehu, that inverter with limiter you showed. They do a 45-90v ver of them as well as the 22-45v ver. Not sure if those are 120v out tho.

Awesome....

I am thinking about upgrading my parents camper with a good li ion pack and an inverter to run their camper. lots of the remote places they go dont have electric hookup. would these cells be a good choice?

Man! You're really dedicated! Go on...

I agree with pulse jet, they are better than anything that’s out there and I’ve been looking and comparing.

I think you should wave the camera around more! LOL. Luv ya man, and you really make me want to spend more (and this vid shouldn't be watched while drinking).

Goo is the technical term for conformal coating 😉

jehu , about the Solid State Relay ..... it will probably not work .... most of them are just triac, which re a specific kind of transitor , that REQUIRES AC to work, what will happen is that it will turn on but it will never turn off again ,unless you unplug it from the power source, which is kinda useless

I thought you were having trouble with the BMS output. Can you clarify that.?

Any idea what brand/model scooter these came from? I just ordered 4 to experiment with and would like to take a crack at the BMS.

Over time the Clear Araldite of the BMSs will heat up and cause a fault of some kind. Just letting you know for the future. You may get luck too and thing happens hopefully that is the case. Stay safe have a wonderful day.

Got my order yay have to wait till the 1st to get 40 batts will a Solar Charge Controller work in place of a BMS

Not instead of one

Yep they went totally Skippy with the Silicone on the BMS. Super pain in the rump to remove the BMS. BUT I have to. Going 40P 7S here. Realized I can spot weld fuse wire right on the left over nickel strip on cells. No need to pick and clean each cell. Just clean them up some and test . Using 6 AWG wire as bus bar each side down pack set between the two rows of cells. Spot welding fuse wire to said bus bar . Using the 6 AWG bus I can pull 50Ah out of the pack no problems. Only tested first 40 cells . Nothing under 3000mAh. Most around 3.3Ah. Man these cells are decent. Each set of 7 packs will provide 130Ah of power to my system. For this price I'll do the work. 2nd set of 8 packs got here yesterday. LOL 2 day shipping to New Mexico ? If there still around next month I'll be ordering another 16 packs. I'm a political prisoner on Face Book right now. Using Jab on the group.

This looks amazing - fantastic work. But how much does the entire power wall cost to put together? Is it not cheaper to use other larger cells (like CALB, etc) that are used for off-grid solar array setups? What are the full specs of this build? ie, voltage, max charging rate, max discharge rate, etc.

Doubt it lifepo4 is really expensive like $400/kWh and these are around $100/kWh

So you can use the 240v but cant use it huh? Lol...love ya jehu. The 120v option works out better all around

What kind of Buss Bars do you recommend?

I been experimenting with my batteries, i have those same batteries but with the cable connectors, case and manufactrurer details, the main problem with the bms and whole charging system is that is controlled using CAN protocol, so far all i can worked out is that the battery is asleep, it can be charge directly into the black and yellow wire but then nothing goes out the battery at all without connecting the whole system, this battery is the only source of power for the bycicle, so once connected to the controller, through those 8 color wires near the 2 big negative cables, it will send a very small voltage to the system where the gsm, tracking, display, etc is... now, if you clean the board where thos 8 cables are you will see more or less what each does, the CAN system will give the bike just enough juice to be standing by until a user hires is, once an user hires the bike the system wakes up the battery and unlock the rear wheel lock cable and the bike has full access to the battery, once you finish using the bike and plug the rear wheel lock cable in, the system goes back to stand by and put the battery to sleep. Other problem i been having is that you would assume there is a constant power going out the batter through those 8 wires but the maximum i can get out is 0.06v i think, which is another problem and if you remove the battery from the system you would have to kickstart the system some how, THIS i could be extremly wrong and i am unable to test the full charge of the battery at the moment, i am doing all these test without removing any of the clear gel protecting the bms but it seems that i will have to remove the and test the whole pack properly so i know proper numbers... By the way the 0.06v reading i got are steady

@@giorgioarmignacco1346 Hi... I think i spotted what we actually need, i was looking into some relays and i got the info from this chip S50085A, i think is what controls the ammount of power to the CAN system. www.infineon.com/dgdl/Infineon-BTS50085-1TMA-DS-v01_00-EN.pdf?fileId=5546d4625a888733015aa435bccd114b Here is the ARM chip which i think deals with CAN. www.nxp.com/docs/en/data-sheet/LPC11U2X.pdf I am also thinking the MOSFET between the 4 in one side and the S50085 can be the one one letting the 36v out the batter marked "Q20" I need to track the pin out of the yellow and red wires as i think they go to the D9 and D10 then to teh U6 and Q20, if the so hopefully yellow to D10 the U6 to charge the pack and something switch the Q20 on, maybe the U8 to D9 out as the U8 seems to be a regulator, maybe it senses the low voltage of the pack and cuts the Q20 out to stop the pack from going below the voltage... This clear silicon is a nightmare...

Don't you have 220-240 (208?) volt, if you connect to 2 of the phases of 120v, instead of 1x 120v and neutral?

@jehugarcia

4 жыл бұрын

Yes, but my circuits are spread out over the 3 phases, so if a 220v load is over only one of the phase that the inverter is on then I’ll be back feeding into the grid. It’s just too messy, if I use 3 of the smaller 120v inverters one on each phase it’s just more elegant way of dealing with any load.

Why not get a 3phase inverter? Or UPS, and use it as inverter?

Would be worth to do a collection between people and pay someone to figure out that bms.

Do you have this build documented other than these videos? Videos are great but they don't always tell the details, like wiring digrams.

3 phase 120/208 volts.

just use a small relay on the ac side.

Don't forget to mention that the goo smells stinky!

Let's crack that BMS, buying a third party BMS makes no sense when you already have one!

Your basically going to be able to power your entire shop off these batteries, is it 290ah? Or was the math wrong?

I highly doubt your supply voltage is 120v 3 phase. Normal North America is 230-240V 3 phase. In the panel they they use a neutral to ground to give 120V single phase circuits. A 230/240V single phase circuit is connected between any 2 phases. Three phase power is connected to all 3 phases. There are also 2 different types of 3 phase power that can be supplied to the building. "Y" type and "delta" type. Typically, 230V will be "Y" type, 240V will be "delta" type. Connecting to the panel with inverters will need to be done with a proper 3 phase inverter, not 3 single phase inverters. It could cause major problems with the grid connection. Also any 3 phase motors will not work correctly. They depend on the phase difference to operate properly. You can NOT treat 3 phase power panels like a single phase home panel.

@briandolbec37

4 жыл бұрын

Also "delta" type power is neutral-ed differently than "Y" type and requires a different panel wiring to get 120v single phase circuits. You better consult with a qualified electrician before connecting any inverters into your electrical system.
