For a vehicle, I liked it. For a power outage, I like it. To reduce pollution by recycling is another reason to build it. For info, I am glad this video is here. Just make sure this is feasible in your area. $125/Kwh per 1000 (?) full cycles = 12.5 cents per kWh. That's about the same rate we pay in Florida for FPL.
I know you did this video a long time ago, but some of my tips will still apply to future endeavors. It is almost always a good idea to put a series resistor in a micro controllers serial line. I use a 1000 ohm resistor most of the time, unless you use a very high baud rate (115200 baud or more), then a lower value resistor is called for. Now, you can get a high voltage of the old reliable LM317 regulator, I think it is an LM317V. I use them to power micro controllers inside my solid state power amplifiers that use 48VDC. The regulator has a 60VDS limit. An LM317V and a couple components and you can make yourself a 3.3V (or higher) regulator.
received some of these from you last week, the connectors are in great shape!! Love how the whole thing is wrapped in the aluminum sealed inside the plastic with only two leads out. Thanks Jehu!!
For anyone who cannot get their pack to wake up, here is what worked for me; the packs seem to have a lockout, which Jehu tripped when testing with the inverters. If you trip this lockout, connect the arduino as he showed in the video, then give the pack power on the smaller connector, the larger one does not work at all when the lockout is tripped, at least for me.
@@theman56 Before charging the meter read about 15 V, which I believe is just some leakage through the mosfets. In reality, it was at about 33V, which I could only see once it had started charging and the mosfets had turned on.
Hi, the code for some reason is not working i tried multiple Arduino and i double checked all my connections and everything is correct . still not keeping the pack alive, please help
Badass setup!, can imagine running a few of those with a decent pure sine wave inverter and solar panels to match the power Wao so much power in such compact enclosure. Thanks for the video!!
Very informative video as always, I am in look out for similar sealed batteries for my home inverter. Right now I am using a 900VA, 220 Volt inverter and a 150AH lead acid battery which manages to support 5, 6 hours of back up. How ever owing to frequent power cuts, the battery life is very short and its quiet expensive (to Indian standards) to replace every couple of years. I am considering to pick 3 or 4 of these sealed battery packs if you will be able to ship them to India. I have an Uno and a Nano which i bought for project. I am an Old timer so not so much into these online transaction and/or social media stuff. I apologize if this is an odd post here.
Ya led acid batteries aren't supposed to get low in voltage it makes there life expectancy drop every time only deep cycle have larger plates inside and can handle it so invest asap in different bats if you don't believe me look up car batteries for solar storage it'll explain everything
The arduino has multiple outputs. Just make new code sending individual signals and wire them individually to each output pin.. the uno has more pins than the smaller one..
Hi Jehu I am new to your channel. Cool stuffs you've got. Quick one. Can you have this system setup and have them for sale for some of us overseas where sourcing couple of DIY stuffs are challenging?
Do not connect a non-5v tolerant serial line to a 5v output. Even with paralleling them all together, it makes no difference as the serial receivers inside the BMS draw virtually no current from the line, so you can never 'pull the data line voltage' down far enough to be within the 3v3-3v range. At best, the receivers are 5v logic tolerant, at worst the receivers will eventually be blown out after being pushed beyond spec and you will have effectively killed the BMSs.
@@OHydroTsunamiO You'd need new ones that play nice with the exact type of batteries otherwise you have fire hazard and / or kill the batteries. jehugarcia seems not really very proficient with electronics which is sad because the idea is great.
Jehu, is it possible you are seeing resistance build up on the DC Power strip? maybe that is why you show a lower amperage the further down the line you go as you test.
@@ItchyKneeSon Center tapping between the 2 strips instead of daisy chaining 2 in line would cut it significantly... other than that just have to beef up the conductors to stop voltage loss
Great idea, can someone recommend good and more powerful inverters for this setup? I Don't like the idea of having a lot of inverters. I rather have few but more powerful. Thanks
The Amazon link for the inverter is no longer working. Can you recommend a cheap inverter that can be grid tied? And how could I change how much power is being supplied by the system to the grid?
So I’ve started prototyping a nice plug and play solution for people who just want to have a no fuss operation of this battery’s. Dose anyone have more information on the BMS like chip IDs. As I also want to build a smart version that will hopefully give us some battery information from the BMS

Pretty dangerous choice of ac output sockets in those grid tie inverters. Why not choose male panel connectors instead,, as old PC power supplies used to have for powering the monitors..
For integration with an existing grid tie inverter (Sunny Boy 5kW) would it be safe to wire 4 of these batteries in series. The inverter requires a minimum 120vdc to start. If that’s safe, any recommended BMS to allow for safe, automatic daily recharging when the sun is up (looking at Victron 250v MPPT Charge Controller but thinking it still needs BMS to keep each of the 4 packs in balance).

On the scooter there must be a way to power the main board even with the battery shut off. Otherwise how can the main board switch on the batteries without being powered? (Something like BEC on ESC)
The battery always remains on. Only shuts off with large 1-2A loads without signal. That’s how it runs systems. There is tx, rx, alarm & positive /negative load leads. That’s it
@@jehugarcia haha ok. Nothing found online anyway. It could be something like an electric lock. I think the only way to figure it out is to test and reverse engineer the unit
@@jehugarcia I just got a few of these from you (thank you) and noticed that both were on at about 15v on the discharge terminals... is this expected? For what I need, 15v is actually perfect.

On the scooter there must be a way to power the main board even with the battery shut off. Otherwise how can the main board switch on the batteries without being powered? (Something like BEC on ESC)
The battery always remains on. Only shuts off with large 1-2A loads without signal. That’s how it runs systems. There is tx, rx, alarm & positive /negative load leads. That’s it
@@jehugarcia Thanks for your reply. And what is alarm cable supposed to do?
You tell me
@@jehugarcia haha ok. Nothing found online anyway. It could be something like an electric lock. I think the only way to figure it out is to test and reverse engineer the unit
@@jehugarcia I just got a few of these from you (thank you) and noticed that both were on at about 15v on the discharge terminals... is this expected? For what I need, 15v is actually perfect. Do I need to only wake it up to charge? Or is the signal only required if I want to discharge at 42v or greater than a few amps? Thanks
This may not be the way to do this but does anyone know why on his site I would be having trouble placing an order trying to buy some scooter packs but it’s not letting me push any buttons thank you very much
Yeah, let's test the battery, plug in FOUR INVERTERS on at the same time....what can go wrong....
Too bad you are not shipping those to Canada...
Yes I wish I could get them in Canada
Me too guys. Sucks we can't get them here. Hopefully he will look into a way to get them here for us.
Hi there, we will be importing these into Canada again, please contact
AffordableEbikes@gmail.com Subject : Powerwall Packs + Quantity Desired
They will be priced at $100CDN + shipping which covers import taxes
Please respond at earliest convenience so we can get proper estimate of numbers for import

Hey Jehu big fan of the chanel been watching since the bus conversion. I'm a Canadian and I REALLLLLLY want to buy batteries from you but I see you dont typically offer shipping to Canada. Could we please work something out. Its so hard getting well priced batteries here. I desperately want rid of my lead acids but cannot afford to spend the thousands required.
I can’t ship internationally
@@jehugarcia aw thats a shame. Is there no way to do it. I seen another 3 canadians in the comments who all seem to want batteries. Id pay the extra or wait the time for a different method of shipping.
Short of you sending me a label I can stick on the box and have it pick up.
@@jehugarcia I'm going to look into that! :D what state do you live in? I'll try and research a way to have them shipped. I wouldn't mind paying in advance. Do you have a business email I can correspond with you directly? I'm going to be doing my research on getting these shipped to me, ill take care of figuring out the shipping information.
Battery hook up ships to canada with no issue at all.
LTO cells - whats your opinion please ?
can i ask you some questions on a particular battery?
Is there a rechargeable cr435 pin battery?
Too bad they are 36v. Kinda the same problem I have with my A123s
I need them ... !
I want to convert a Hinda CRX to electric, how would it be done?
probably not by asking in youtube comments
@@zachhoy Smart ass.
I notice in this video you have mating connectors (on the load side at least). Do you have these available for sale?
Warning, Scam!
@@quietwon8992 Actually they did have the mating connectors and I did buy them. At the time repurposing these batteries was a good option for me. Today it is not because technology has moved so far so quickly. But it was far better than lead acid which I had been using for the 10 years previously. Jehugarcia is definitely not a scammer. He buys surplus batteries and helps people put them to other use... economically. He's a good guy.
Question : Pack is 10s but the meter is 8s. Why use the 8s BattGo meter?
To power the arduino via the USB charge port
@@jehugarcia OK. So, it there a recommended 10s meter?
Doesn’t exist
@@jehugarcia That is disappointing. How does one monitor 10s packs? I have two arriving today (from you !!). I have a 10s BMS. I have a meter that can see the whole battery but nothing to monitor each of the ten.
A regular meter, i have the one I used linked
siiiick
How many cycles can you pull out of these batteries?
I myself would guess around a thousand, depending on many factors, since they are Li-Ion packs and probably optimized for power output...
@@GantryG How did you arrive at 1,000 cycles? Are these USED packs? How many deep discharge cycles have already been consumed?
@@GantryG Gotcha, yeah Lifepo4 is a better option for a solar wall in that since you'd get 3-5k cycles.
20 feet.on a ebike! Useless
Cool 😊👍
Viel Arbeit aber gut 👍
