We use Ford C-Max (Energi) 7.6 Kwh per battery and we pay less then $75 per kilowatt and they are Panasonic made in Japan cells. Been using them since 2018 with no BMS and they run our home 24/7 and yes, I have checked the cell voltage a few times and they have stayed where they were when I purchased them so take it or leave it.
I've built two EEL cases and both times dropped a screw in the back, which fell through the slots. Try using the foam cutouts (scrap, for the battery vents) to block the slots in there before you install the balance lead bars with the screws in the back
There aren't really any links that I know of. I got these from Jenny and she can send you all the details about the products. Her information is in the description.
I'm interested in knowing how easy it is to connect this to solar panels? Watching the build was really thorough I really appreciate what you did there.
Thanks so much for the video! How much do these units weight when assembled? Did you assemble in place or get a couple friends to lift and place the assembled battery pack before wiring it into the central bus bar?
You would have to buy three EG4 100ah batteries to get the same as what you would get in this build. Check out the prices of the cells, and the kit to compare.
bought the parts last week, all the parts needed using EVE 280Ah cells and this Case from USA stock (which has already arrived, FYI, less then a week from ordering with a Holiday Weekend) came to a little under $2,200, by comparison the current lowest price on the EG4 PowerPro Indoor model is $3,299 (before tax), so it's legitimately 2/3rds the cost of the EG4 or more if you are in a state that doesn't go tax free on solar, the final savings vs the EG4 PowerPro indoor came to $1,345 and change.
a question: what is the value of this kit over say an EG4 LL? These kits with a batteries are much more expensive in dollar cost, and have the added expense of needing to be assembled?
ok rather than delete/amend, i'll reply to my own post, since I didn't do enough diligence. So looking up the total cost of an EG4 LL-S delivered to me, it'd be ~$1700. the complete kit ((China stocks) 15KWH DIY Battery : 48V DIY 280/304 kits + 16pcs EVE LF280K V3 cells + Inverter cables + RS485 connector) would run me ~$2000 delivered. So for an extra $300, it's nearly triple the capacity. It's a lot of scratch to lay out at once, but it's also a lot of capacity.
I am yet to see a production battery with insulation or venting (while there should be because of explosive risks) . If you have a link, share it. It's been quite some time since I bought these. Check with Jenny (in the description) for a current price.
@@BecomingOffgrid Um, yeah, but you didn't say inch pounds or foot pounds. You said nano meters. There is no torque measurement ANYWHERE that is "nano meters". What a strange response to say "well it's measured in inch / foot in the US". Newton meters are also used in the US, by the way.
A disconnect needs to be added to these units, have 2 of them and if the bus bar that they are connected to is live the unit will start charging or discharging no mater what position the push button is in
Thanks for the vid. What is the amp rating of the bms? Do you know what bms it is? Are the boxes stackable? Do you have an idea of the weight? About how long did it take to arrive? What was the cost? So many questions -thanks
Its an Apexium BMS 200A model. The boxes are stackable They are heavy - like need more than one person heavy Mine showed up quick as they have a USA Stock, but ask Jenny and she will tell you I don't want to share a cost, that locks Jenny (and you) into whatever price I put on here. It's not my place to say or speak on her behalf. I would ask her for pricing as this market is constantly shifting. I can say that the first round of cells I bought two years ago were quite a bit more expensive than the ones I just bought.
You can get 16 brand new EVE 280ah cells from battery hookup for $1,640 plus tax and shipping. They have 24.6 KW of New Gotion 16S 52.2V modules for $2400 plus tax and shipping. And they guarantee everything they sell.
is that in pesos or yen? each 280Ah Eve cell is currently around $90-95 USD and the Box and BMS was like $600-700 USD, the out the door shipped price last week for me from USA stock using EVE 280 Ah cells and this box was $2,184 paid via Paypal. By comparison the CHEAPEST Price on the EG4 PowerPro Indoor Model battery is $3,299 BEFORE Taxes, with Tax (for me anyway) it jumps to $3,529.93 so I saved like $1,345 by assembling the battery myself.
I didn't say because I'm not a salesman for Apexium. You will have to ask Jenny for the current price. Mostly because the cost of cells fluctuates a lot.
@@BecomingOffgrid Yeah, but we come here for information and I see nothing wrong with mentioning the price. I am well aware of price fluctuations and don’t want to fill out some form giving a bunch of information for a simple price.
It's not that simple. 3-5k would be my best guess per pack. If there is a high demand for cells you could pay a lot more than when there are times of little to no demand.
the feet on the bottom are held on by a bolt up the middle of the foot, I don't have proper measuring equipment to confirm it, but i'm fairly certain it's a 1/4" diameter, 20 TPI (thread per inch) approximately 5/8" long bolt that can fully seat all 5/8" of length easily and possibly slightly longer, using that information I started searching for threaded casters, the closest I could get had 1" lengths threads, I ordered those, should be here thursday/friday and I'll be able to confirm if thats the right bolt size and thread pitch by this weekend.
Good job & nice build, looks like a solid unit, I did notice it is missing the Confirm (yellow) button, or is that how it is meant to be? Would be nice to know more details of the BMS used, type, surge capacity, balancer type & current, etc… I would double check ur sequence for installing the balance leads & battery main leads, as I thought ur supposed to tighten down ur battery leads before plugging in ur balance leads because if ur 1st & last balance wires are mot making a good contact when you plug in the leads it can give a BMS error msg, but it may not be the case with this BMS. What an excellent build this is, been checking out ur other vids, good info. Cheers
The yellow button didn't fit because I put the sticker on crooked. The rest of the data you are asking for is straight from Apexium. The BMS is apexium and it includes a balancing function. Its a 200A BMS. Jenny would honestly be a better person to ask those super technical questions to. I don't really know all of those answers.
Fantastic! Was really looking forward to your build after you’d mentioned it in earlier video. Makes so much more sense if you’re going to power a whole house. Guess I’ll have to get me some. How low a percentage do you normally cycle these down to? ⚡️☀️👍
Is it possible to operate these Apexium battery boxes standing up vertically? Hadn’t seen anyone do it yet but if the cells are clamped down into the box I thought it might be possible? 👍
@@terrahillfarmYea they should be just fine running that way. Plenty of people out there have the cells laid flat in production systems. I would ask Jenny if there are any designed for vertical orientation coming down the pike. May be worth the ask and wait if they are.
@@terrahillfarm I was told by a rep. that they are not designed to be vertical but if you must, to secure it very well. There are boxes designed for vertical, EEL makes one.
Good job. I am on my way to build myself one. I bough the DIY box kit from Cassie Zhang (I'm from Europe). Next month I will buy the cells. From what I saw, eye-shopping around, this kit looked ok. Yes, for a 15kWh battery, the price is around 2/3, and you learn something in the process. I have 22kWh installed already (from ready made batteries) and according to what I know now, for the price I should have 32kWh. I do believe that DIY is the way to go as the readily made batteries become more expensive instead going the other way due to the increased number of manufacturers. Anyway, here in Europe, the energy is quite expensive and being self reliant on it is a must (due to prices and the less maintained grid). Let's not forget the natural disasters that could become more frequent due to the already well felt global warming. Having more EV's is putting a strain on the grid. I suppose that on the long term, if nothing happens (like WWIII), the batteries prices should go down.
@@iviemaro380 better ask yourself because the prices have dropped. Second what is good price for me, maybe not be good for you. When I decided to proceed and do use a DIY box kit & cells, my reference was the price difference between it and a ready made battery. So gather prices for (1) DIY box kits & cells vs (2) fully assembled batteries and see kWh/kWh which is more reasonable from the price point of view. Bare in mind that you must take into account the (3) shipping fees (which will vary) + (4*) your own time spent to assembly the battery (* optional if ou want to have an accurate estimation).
@@iviemaro380 the actual DIY assembly time is no more 2 hours if you want to take it slow. Have all the instructions printed or on a computer screen to constantly check them. Also once you have the cells, I strongly recommend to link them in parallel for a couple of days, to be sure that they will ballance themselves. If you buy the cells in one go (from a trustworthy source), it is quite like that they will arrive already balanced. In my case, I bought them in two batches, at at least one month apart.
I bought 16 cells from jenny wu and 3 of them came dented and scuffed. One cell had a dent the size of a penny and depressed about 1-2 mm. I spoke with Jenny and she said that they can still be used without ill effect. She denied an exchange. What do you think about that?
It took a lot of back and forth with Jenny and FedEx and I am still not completely satisfied. Fedex only covered 1/3 of the damage and Jenny Wu (and company) would only cover another 1/3. I ended up having to pay $127 for them to ship out 3 replacement batteries. I think Jenny Wu should have covered the cost completely. I also think having to wait a month is pretty shameful. BUT I guess it could have gone worse. Well, it did get a little worse..... I also had a problem with one of the Apexium boxes. One of the temp probes was not soldiered on to the balance PCB correctly. This took me a couple hours to figure out and kept my battery offline for a day..... It was actually just glue that was holding it to the PCB and keeping the temp probe leads in contact. I let Jenny know about that and took pictures to make sure their manufacturer does a little better quality control. They are sending me a new board. This is the price we pay as first adopters and DIYers.
Thank you sharing a very interesting video Can you please share details related to the BMS I have two Pylontech US3000C installed with 5kW Solar PV Panels and Solis Hybrid Inverter Now, I am thinking to totally go off-grid and looking for good BMS to match with Pylontech Batteries Thanks in advance.
My cells were $2,200 dollars, $200 bucks for a BMS, $100 for a T class fuse, and maybe a couple hundred for cables, lugs, ring terminals, circuit breaker..And I built my own boxes out of wood I salvaged for free, from a project..That is a thousand dollar difference, and my BMS has an active cell balancer and awesome bluetooth app..I don't have communication between my all in one inverter/solar charge controller/AC charger, but, don't need that at all..Don't need a shunt either, I have way more battery than loads..But, I do like those boxes...And maybe I could have communication, never tried to connect it up..
They are really for fire prevention. I know LifePO4 just smokes and simmers - and I want that to stay contained. Too many posts on "Up in Smoke" on the DIY solar forum for me to take the risk.
Hi David & Real, there's ~$700 difference between your prices, Real goes into more break down detail, David's appears way more expensive if just inverter cables. Could you clarify total build cost for me please, incl where from, Ah cell, resulting kWh, assuming you both did 48v/16s, & are based in USA (way cheaper & more availability vs Au) Be also great to see same answer from yourself Becoming.
The difference between the three is after sales support. I have seplos and eel cases as well. My experience with them was not good. EEL lied about the cases being in the US and My seplos cases came with damaged battery cables they refused to replace or even acknowledge. Seplos gave me firmware to flash to my BMS that bricked one of them, and then they refused to warranty that BMS. Different strokes for different folks I guess.
@@supermo26 As far as build out goes they are all close to the same. The cases for the Apexium and Seplos units are thicker steel than EEL. The after sale support for Apexium is great. I will never buy from Seplos again because they didn't want to support their product.

@afreemanreigns did you bottom balance these cells?
What happens when one cell decides to die on you?
And get reverse charged?....
I use the same cells from Docan. Several orders, zero issues!
They have worked great for me for the last 2 years! Thank you for watching.
I've built two EEL cases and both times dropped a screw in the back, which fell through the slots. Try using the foam cutouts (scrap, for the battery vents) to block the slots in there before you install the balance lead bars with the screws in the back
This is a good tip.
how about communication between this Apexium battery to the EG4 or the sol-ark inverter?
My EG4 comms works, but it's not great. I haven't really dug too deep into why.
