$3870 for 10kwh is a good deal. It compares to a $500 1280 wh battery. Additional savings comes from the reduced wiring requirements plus having a battery monitor build in. I guess they are finally taking on the diy firewall market. My planned system is - 8 kw Solar - 32 kw 48v battery Just 3 of these batteries would do the trick. I won’t be ready for another 2 years, it’s safe to assume the competition will increase and the price will drop. Exciting times.!

SOOO glad to see you testing these. We purchased one back in July/2020 and think its a BEAST. We went with a 48V 10Kwh unit. EDIT: So we just noticed our battery is not even remotely reaching the state of charge you show in your video. (our ceiling appears to be 53.98V) Should we be concerned? We're also in a much colder climate in Idaho! However, the battery lives in a heated workshop at about 58 degrees.

BYD just recently announced that they now can produce their BLADE batteries for less than 100$/kWh on the pack level. These batteries are rated for up to 10.000 cycles. That’s for the automotive industry, batteries for home storage usually are a good bit more expensive, at least for now and of course it’s not the price for the consumer. But I expect the prices to drop by about 50% over the next 12 months. At that price point you are down to 2-3 cents per cycle/ per kWh. That makes these batteries interesting not only for people who have solar, but also if you just have hourly tariffs or want to cut down your peak demand. Once people have the batteries, of course they will want to have solar as well.

The BYD Blade batteries are an exciting technology. I hope the car that they're being shown in, the Dolphin, makes it to the US market someday. Googling "BYD Blade batteries for sale" brought up a listing on a Chinese retail site for me. I'd be interested in seeing who goes first in sourcing them for a DIY solar project, or even a DIY EV project.

It's a really good time to be getting into solar and thinking about power walls. I just had a 9kwh system go on the roof with go-live in about 2 weeks, but it's strictly a grid-tie system with no off-grid support (batteries). My SO remembered Tesla Powerwall and got all excited but I told them no on Tesla due to all the problems and high cost. Trying to steer towards an EV battery for price and safety, but seeing products like this starting to splash down is exciting.

Roughly $2 Australian per kWh which still makes sense to me, even at a severely reduced capacity. All the best :)

Riddle me this Will (please). My first started on your channel it was to add a solar system to my RV. Back when 20, 50 80 watt panels were popular. Anyways you had just come out with your book and I bought a hard copy. So I've been watching you since then. With knowledge obtained from all your videos I've installed solar system on the last three RVs I've owned. The very last one I use those little 50 amp reclaim batteries from the hospitals crash carts. I picked up six of them for ridiculously low price. It worked awesome we never were concerned about running out of house battery power. Anyways I sold that unit about another one, it came with one 12 volt battery that I upgraded to two golf cart batteries. There's a lot of things needed to be upgraded or fixed/repaired on this RV so inexpensive golf cart batteries was the way I had to go at the time. What is the most cost efficient lithium style battery that you would recommend for an RV? Thank you very much congratulations on your success and your improvement in health

Thats still mighty pricey. I paid $1500 for 8kwh, but to be fair, i had to assemble it my self and it does t look as pretty. All parts considered, i still paid half of what they are charging. Assembly is simple - get batteries, assemble on a flat surface, with 90degree angle to butt it up against. Glue cells together temporarily with hot-glue. Order nickel strips, cut them as needed, build basic welder using a button, car starter relay $35@local parts store, and some thick copper wires mounted on a wooden block. Use car battery for the power source and get a solid fuse to prevent stupid mistakes. Get hole saw, cut holes in the right places on a couple 2x4. Cut 2x4 along cener through the holes to provide a top-bottom supper. Sandwich between two ply board cut to right size, leaving room at top to mount BMS and DC fuse. Connect wire, add a connector like the one seen in the video and bam. Ive made 17kwh of power my self. Couple to 6000w of solar panels and midnite 150 solar charge controller. Make a LVC using $12 programmable delay with thermistor connected to the normally closed side of the board relay, and a 12V 100A relay connected to the normally open side of the board’s relay. This provides a soft start/inrush prevention to keep from damaging the inverter, and prevents the relay contacts from welding together, so the charge controller can shut off reliable when the voltage gets too low. I run two AC units, one that draws 1.4kw and one that uses 1.1kw. The second AC unit only comes on when it gets really hot otherwise its not needed. When the sun goes down i normally have 15-16kwh of power to: charge my neighbors car with the excess, run my two computers and do a number of things. The BMS has thermal cut off, but because the system is capable of taking in 3.4kw of charge at 1C, and charging never exceeds 4.8kw, the batteries NEVER heat up beyond 31C, in the summer, under full charge load. These batteries wont heat up appreciable until they reach 1.5-2C charge rate, which my system never achieves. If you are a DIYer, dont waste your money. Takes a few days to put the batteries together, a few days to charge and test. Batteries come charged at 3.2V per cell. Charge pack until any of the 16 rows of cells reach 3.45V, then using Variable DC power supply ( $50 amazon), charge each row to 3.65V and wait till final charge rate settles to .07A, perform this once more for each row 12hr later, then bolt the shell together. Bam. They are ready. BMS will balance them from here. Its been a year since my last balance and the batteries still dont need maintenance. If you have time and have the skills, dont waste your money on something like this

What enphase do right is making them modular. That eliminate the need to move something so heavy. Further, it is expandable and component replaceable. What really needs to happen is to make all in one unit easy for consumer to use, install and maintain. It needs to be modular, otherwise too heavy. Your videos are great.

Great video. I just subscribed. It's funny hearing you complain about how much that battery weighs. We installed our off grid system almost 6 years ago and went with flooded lead acid batteries. Our battery "system" weighs about 7500 pounds - so yeah that's heavy. I'm certain when we are forced to change out our batteries in the future, we can convert to a much lighter technology. I hope that's at least another 10 years out. We try to never drop under 75% SOC.

Will. To set things up, I worked in San Antonio, Texas years ago where I worked in shipping containers that had been converted into storage. The temperature inside of those things would reach 120 to 130 degrees F even in the insulated containers. There were even a few times that they approached 140 degrees F. All of those containers were water tight and little air circulated through them. The containers that I worked in had open doors. God only knows what the temperatures would be with the containers closed for several days or weeks. Listening to you and others that review DIY prismatic cells two common threads are that the ones from China are weeks and months in shipping and quite often the cells that you all recieved were puffed up. More than likely, they were shipped in containers like I described. I have two questions in relation to this information. First, knowing that heat is bad for Li batteries, would the heat that I have described be harmful to cells that are in transit for weeks and months? Second, would a person be better off paying shipping fees for faster transit so that the cells that arrive have not been cooked for days and weeks on end? I know that grade B cells are often pawned off in other countrys by Chinese firms, but how long could they really get away with that practice before word spread and they couldn't sell in the US or Europe? For those reasons, i belive that at least some of the problems that we see with battery cells out of China are the result of poor shipping practices. 'What do you think? Thank you

Good work. I'd like to point out that a 20 year warranty has some value even if the company goes belly up, since most companies don't plan to go bankrupt, which means that they plan their warranty policies to be financially viable, or in other words: the product is designed to last that long, (while a product with a shorter warranty is designed to break sooner). One more thought: if you want to orient them the way you wanted initially, and still be able to access the screen, you could probably set them up like drawers in a vertical "tower"... maybe even use a couple of small mirrors per battery, (a "mini periscope"), to avoid having to pull each of them out just to check their state.

You are right that there is a lot of energy that can come out in a very catastrophic way if not well designed. Keep up the good work!

One of the issues with these batteries is the low C rating requiring multiple units to run a larger system. Requires one unit to run a 3 kW Inverter.

One thing I see that concerns me is how the negative group of cables is laying over the positive pcb. When going back to 2:20 I do not understand why there is the big loop in the negative carriers when they could have easily been routed straight into the battery area without looping over the positive side of the pcb. Strange. Even with the white plastic wire looms over that bundle of negative carriers, I am not comfortable. I have been a bench level tech and lo and hi V installer for many decades. Even in fixed applications, I try to avoid any near or cross placements of different polarity carriers. While I recognize that space is at a premium in this battery system, it only takes a few seconds for high amperage dc power systems to go very quickly into a disastrous situation.

Just a thought, based on the locations of the main power connector, communication ports, and handles I think they intend this to be installed in rack mount configuration flat on its back. Yeah the control panel would be a bit more difficult to use but depending on the space between the cells when you rack mount it it should be visible enough (or you just pull it out far enough to read it). My guess is they are assuming you are going to use multiple and hook them all up together with the communication ports to a unified monitoring panel anyway after the initial install so the local control panel wont really be needed after that. So if that is / was the case then you wouldn't have any issues about the cells stacking up on each other or the electrolyte possibly not being distributed properly. Thanks for all the vids, I have learned a lot watching this channel!! Currently working on putting together a small pack for camping and contemplating a larger one for a camper.

Though we are using mainly DEYE Hybrid Inverters in our install, the usual problem of these batteries is the DC Low-Volt Fault and sometimes the batteries don't balance or just becomes fully drained. The batteries just automatically returns to its normal condition after Inverter firmware update. Though I'm confused as to the reason why these faults happen.

This beast is a little out of my price range of $3,800. 320ah prismatic cells are cheaper and weigh in at approx. 11.5lbs.....so doing the math and multiplying that by 16 would put a DIY weight around 185lbs. If you separated the cells into two 24v packs they would even be more manageable to move around, could be stacked or shelved easier, and connected/disconnected in series for use, or maintenance. Also, doing a replacement of just one cell in this beast is going to be more difficult to find. And, when it comes to watt hours, this beast is only 200ah. A DIY 320ah will be closer to 15Kw. There is a lot to think about when it comes to making this purchase. But, I can see some people buying into this battery already made, and not having the knowledge or skill to make one themselves.
