A stack of battery packs like that would be perfectly suited to a FLIR type of infrared diagnostic tool. The IR camera will show you which battery packs are running hot, so you can plan for replacement.
In some states the power companies will give you discounted power rates in off peak hours. This is a set up that could pay for itself by charging the batteries in the off peak hours then in peak you remove yourself from the grid and use the power you saved from the night before and you are helping keep the power grid more stable.
I wish to see more and more VPP solutions on the market. Trading electricity in a real time on the markets and making money for you, but you not doing anything for it) Just build and use.
Depending on what the efficency is you are correct. I wonder how much energy is lost in charging these batteries during off peak and utilizing it during peak times.
Easy to put together. Not so easy to design. Understanding what can cause thermal runaway (fire) I think is the most important. You definitely have to make sure no individual cell gets over charged.
Picking packs 9 through 20 in about a week (last in stock near me and cheap.) Managed to hit the $100 per kWh on the packs overall so the tough decision is not to harvest out and stick with the 36v environment OR go down the PCB 24v rabbit hole with cell level replacement and more inverter options .... you make it tough Jehu!!!
@@jehugarcia Indeed ... been interesting to say the least. Ive been thinking of ways to adapt to 36V permanently over time if I could manage to craft a 10s PCB board to add capacity or replace scooter packs that may need to be pulled out of rotation. At least that way you future proof the 36v support equipment investment (inverter charger etc) more. What do you think?
Hi Jehu. Great video as always. Thanks. Would it be possible to make a video on a custom metal cabinet for 48 or 64 Eve/Lishen 3.2v cells with locking wheel casters and door. That would be cool. Alternatively any alteration of an existing metal cabinet that would neatly hold 64 of said cells. 🇬🇧🇯🇲
how do you protect the packs from high amps - example if you have 10 packs and charging if bms goes off in 9 so only 1 pack left the 18amp charger will push 18 amps into 1 pack and blow it and discharge if 9 turn off all amps will be drawn out of 1 pack - most scooter packs work on 15-20 amps out and 3-4 amps in so how can you do this safely ??
On your inverter to generator switch power cord, how did u wire that up? 2 outputs from inverter are each a separate leg into the gen transfer switch cord? So are the ground, neutral's both joined....then separate hots to each leg of the gen transfer cord?
Been working on my solar set up and I put a fuse on my series connection load line to regulate the amp draw pull then series connection a Joule thief to get ground heat pull and a resistor capacitor on the series ground connection using the load pull is that acting like a breaker for the load line just wondering working on my wall system for hold charge with a earth battery in close loop with a antenna to charge the ground with radio and sun for a good ground battery
Hey! Any update on the MegaloDongle??? Manage to get a bunch of 36v scooter batteries and was thinking on a way of connecting them without taking them apart. PR!
@@jehugarcia Thanks for answering! I saw you have the boards in stock. The batteries I have are X8F 40 cells 36v. I haven't tested yet but I guess they will have to be awaken. I'm guessing the activator or awakening thing is generic and works for many models? What 36v charger you would recommend for charging this batteries with 3Kw Solar System. Thank you so much for all your content! Bori!
Ahhh Thats perfect! I would double like this if I could. Seems a bit steep on the pricing though if I could afford that I would go that route instead of the DIY wake up for the batteries. I have 40 battery packs and to pay $1100 to enable the batteries that cost $2200 seems fair when you consider the total price per watt, but when I already paid $182 for basically the same setup without the wake up module installed its hard to understand the price. If the price for 4 was around half that price I would start from scratch and buy them, but maybe theres some more to it that the PCB powerstrips dont do?
@@jehugarcia Understandable. I would have thought that scale would reduce the price, but you know your numbers better than myself. It is fair, but not if you already have the other setup. Who knows I may still order it in the future to save some time.
@jehugarcia, that transfer switch has two legs. Did you put the white together and the blue wires together to make it one. Or you feeding two 120 on each leg or side from the inverter? I see two plus on the inverter. I ask cause I was going to do the same.
A listing of parts and where to purchase them would be helpful. The battery enclosure can be purchased as a electrical panel can, just need the dimensions.
I'd be able to get all the scooters out of the river, there's probably at least 150 in the Willamette as it was, as it always has been, about the only thing to do in Oregon if you don't have a bunch of money. See: just tossin bikes in the river bro
I love this. I definitely want to build it on a smaller scale. How hard is it to charge the system via solar? What happened to the charger panel? It would take ages to charge this with 1 charge brick.
Jehu, how do feel about the server rack batteries that come prepacked for 5kw priced at $3.33 per kw for an Eg4l battery system that comes with a fuse and BMS. They are also stackable and seem like a great alternative to DIY system. Did I mention they have them in 48v and 24v?
I've been following your videos for a long time and I've decided to start making my powerwall. . Question . your conection dongle can work with inverter and charger all in 1. or need the charger seperately.
Can you extract the cells out of this battery pack? I watched your other video where you harvested cells from a scooter pack, but when I clicked on the link to purchase them, they are sold out or no longer there. Can you please help me find 18650 cells to buy economically?
Heat does not rise. Hot air rises. So if you do not have good airflow each battery will radiate heat in all directions. Which means without airflow the center battery will be the hottest.
Hmmm, that's an interesting statement. When something gets warm in a vacuum, even with gravity involved, it does tend to stay stationary. However, when there is no gravity, cooler air will tend to "fall" underneath the heat source and "push" the warmth upward. I suppose you could refer to that as hot air rising, but only inasmuch as colder air sinks. Take away gravity and all bets are off.
Jehu, you're sold out of the Master Megladongle... I don't want to order a slave and batteries unless you are going to build more Masters. Can you confirm that more Masters are being built and is there a way to reserve one? If yes, I'll order 20 scooter batteries and the slave dongle now. Please let us know if more are in the mix, thx
Hey Jehu, I was wondering if you have any boards that will work for the night 7.5v Batts from hybrids. I have 4 prius and 3 honda sets. Very interested! Thx
@jehugarcia I have a Growatt 2-MPP converter for my solar panels that doesnt have a battery connection. Is it still possible to build a DIY powerwall after this system? The cables from MPP that go to the fusebox from the house for example?
hello, I really like to build a 48volt battery but I cant find all the parts I need on your website to complete a project. I just don't want to get stuck with parts I'll never use if the other components aren't available. thanks for your videos
2 questions. 1. Why is there no floor clearance? (cleaning and potential water leaks?). 2. What's the difference between Aluminium, and Aluminom? or are you just replacing the "iu" with an "o"?
That looks to be a Reliance 306C 6 Circuit Generator Power Transfer Switch. Its UL certified and code complient in most if not all areas if it is installed correctly as a critical loads panel since it breaks the connection from the main panel downstream for each circuit you want to power so their should be no chance of backfeeding even if the main panel was left on since it breaks that connection before making the gererator socket connection. These are common to find in houses and cabins where you only need a few backup circuits to run on a generator or portable power station.
I still prefer to use a transfer switch (unless it's a grid tie inverter), would I 8 this was wired up correctly Nice use of scooter battery's thought, interesting product
@@kuhrd so shouldn’t it have another set of circuit breakers installed after it as well? None of this would be compliant in Australia, not only would it need circuit breakers but it would need rcds as well, however we use 240v so more chance of electrocution.
Well, as I understand it, after the powerwall is built, connect the solar charge controller to the powerwall to charge the batteries inside the powerwall and that should do it......
