Let’s put it into perspective. That battery is 2x the kWh of a tesla powerwall 3.
Each powerwall will set you back $15k a piece.
Residential battery setups usually cost $1000 per kWh.
This is $80 per kWh.
China’s selling these near the predicted theoretical limits.
Domestic brands are a cool 10x more.
Do you realize what possibilities this opens up?
Instant micro-grids. 3 days of offline power for $10k. Crazy-durable power resiliency.
When packed cells hit the $50-100 kWh range, batteries stop becoming the restraint.
“Virtual transmission lines”, (aka digitally controlled, strategically placed battery storage) become *cheaper* than real transmission lines.
Power becomes fungible.
If the US wants to
My understanding of the bill is that it only removes the tax credits and does not provide any logistical or legal restrictions on this type of device.

aren’t large LIPO batteries of these size a huge fire hazard?
Yes, large LiPo batteries can pose fire risks due to thermal runaway if damaged, overcharged, or exposed to extreme conditions. However, this unit appears to be LiFePO4 (safer chemistry with lower hazard). With proper installation and BMS, risks are minimal—far safer than early
This seems pretty scary from a fire safety perspective. Especially if they are as cheap as possible and made in China. At the very least, they should be stored in some kind of concrete vault outside (buried) and connected by cables to the house. Even if it adds to the costs a lot
It’s also LiFePO4, which is way better than LiPo in that it’s far less hazardous in terms of fire and it has far greater cycle life.
Amazing. Very exiting to see these prices.

apparently this is the company that can make batteries at near cost ?
“Virtual transmission lines” - No, just higher utilisation rates and loss optimisation. Energy still needs to move, you can't magic energy from X to Y.
The fungiable aspect is one of the more critical aspects that people have not registered yet, where X sells directly to Y.
My first question is how many cycles can you get useful output out of this thing before it turns into a big brick of hazmat that you need to figure out what to do with?
China is *literally* “crushing it” with the lithium strip mines.
But for a moment forget all the dead Mongolians.
How long do these cells last before needing refurbishment?
How much energy is lost to transduction in a home battery array?
I’m highly skeptical of this approach.
If you run your house on 52 volts DC and only consume 1200 watts (forget A/C !).
Imagine manufacturing the entire planned home and it arriving and being put together like legos.
If only zoning wasn’t in the way
LiFePO4 is different, and that would have to house 6 200 Ah 24volt batteries, and that does not look even close to that size. It would have to weigh close to 500 lbs as well. $2500 would be aa good deal for that...
Lol, you probably saved a million tons of CO2 in the atmosphere with this tweet.
There’s a fortune to be made on the companion fire suppression module for this.
Most people don’t know how to put out a fire, let alone a chemical fire. I could only imagine how many chemical burns we’d have across the country.
Your $/kwh price chart is completely wrong.
There's been a handful of Chinese suppliers providing <$30/kwh for industrial bulk orders, for at least 2 years now
With these prices in mind, you can have more realistic estimates of the margins of home power installation suppliers
A day isn’t hardly enough in Maine. Power can be out for days or weeks depending on storm severity and location.
A 5-ton A/C compressor uses 3kW. This would be only 10 hours on 1 pack of this rating.
Decentralized energy storage hitting $2.5K price points is exactly what we need. When hardware costs drop, community-owned power becomes reality. China's manufacturing scale driving adoption through accessibility 
We got subsidies in Australia, for batteries and solar, got a few quotes for my place, but not quite yet at $2500/30kWh.

Thats pretty cheap, I paid over a grand for 48v 100AH rack mounts last build I did.
Is there something less fire prone than lithium for home power? I don’t care about the weight savings I’m not gonna be moving my house anytime soon.
just make sure there is no wifi or network connection for a remote kill switch.
While impressive, the powerwall has self-cooling technology to preserve the life of the system, plus it's watertight in case of storm of temporary flooding. Exposing a battery system like this to water is a major fire hazard.
Coming from the same nation infamous for counterfeits and battery banks with bags of sand in them.
How can one be sure this isn't just propaganda?
Lithium polymer batteries (LiCoO2, used in drones for its high discharge rate) are a different chemistry from LiFePO4 right?
Love your content tho, keep it up
You can't even buy the cells for that price. $80 per kwh for a completed pack is not feasible. Those are either misrepresented or used cells. Probably used.
That's a very good price. If they're safe, would be a game changer paired with solar panels.
Didn't china make those two wheel balance board things? Didn't they keep catching fire and burning houses?
No thanks. I'll pay a premium for the brand.
finally another use for that neighborhood storage facility they just built
if installed in an external building made just for it as a bulkhead against fires, Maybe.
I only run lithium iron phosphate for this reason. And still keep it in a separate power building.
Never heard of this brand. Dangerous is bad quality. Tesla powerwall I know won’t burn my house down
fantastic!
now, raise your hand if you want one of these stapled to your house with 100amps running through it…
hello? …guys…?
I don’t know I’m using up like 80kwh a day man, you sure you live in America? Your McMansion numbers ain’t mathing
51.2 volts...does the price include the inverter to convert from DC to AC at 120v or some other standard voltage?
Welcome to Business of BESS. It's been 10y they are building huge battery plants worldwide
Gym shorts for only $10? BFFR… this Fabletics New VIP Member Offer is crazy - the hype is worth it.
Best way to burn your house down for insurance money
The Tesla power wall is more expensive because it also doesn't burn down your home.
It’s China, the numbers they post are about as reliable as anything a politician says.
I would love to see if you could insure a house with this if you can't park an EV in a garage in many places.
Terrible idea.
they are LFP batteries not Lithium Polymer.. nobody want to have these in their home
China’s scaling and cost efficiency on batteries is next-level. The kilowatt-hour per dollar ratio is rewriting what’s possible for homeowners.
Gladly buy some cheap meme shirts from China but you're not getting me to drop $2500 on anything Chinese Tech. They produce mostly garbage that breaks easily and is disposable. We should all worry about the resources they are mining to make this junk.
There’s a very important rule in life to remember: “You get what you pay for.” I suspect these Chinese battery “tofu dregs” will burn someone’s house down. It would be a hard pass for me.

Can someone eli5 why these lifepo are safe and not an liveleak explosive device like I'm used to?
A 30kWh battery…for your house.
That will weigh 540 pounds.
Won’t be moving that with 5 guys.
extremely easy when your idea of 'water treatment' is a drainage pipe to the nearest river.
What’s the fire hazard? It’s not like that’s not a consideration with Chinese batteries and their low QC.
holy shit..... china is going to outpace the US cause the US loves drama more than osmosis
this is degrees better than Tesla in every single possible metric
thats insane
LiFePO4 is a lithium iron phosphate battery. This is not a Lithium Polymer or a LiPo battery.
These are much safer than LiPo batteries. Seems like everyone here is confusing the two.
30 kwh of electricity is $3.60.
Why pay $2500 to store $3.60 worth?
I can a small generator for cheaper, completely mobile and supply more power on demand. A battery solves nothing for a much higher price.
Why are you trying to compete against the dictatorship that enslaves it's people, violates every environmental hazard, manipulates its currency, lies about everything, steals what it can't invent, and heavily subsidizes medium tech industries ?
STOP TRYING TO COMPETE IN GAMES
Witch is great but make it so the average American can afford it. This is the demographic that needs it most. Tesla wall is a good idea but years away from fruition for the common household.
sounds great but US will be locked out of these prices for many years due to tariffs and sourcing requirements for tax credits. US has been missing out on solar price declines for years now due to tariffs.

If batteries get that cheap, then it would be a game changer for India. While we have started installing lots of solar, storage remains a pain
As of now, batteries roughly cost $250/kwh in India, and that's extremely prohibitive for larger installations.

Solar panels are quite cheap but storage remains a problem as LFP batteries remain expensive; ~20k INR/kwh.
A 5MW solar plant can easily produce 25k kwh/day. Such a plant costs ~20 CR INR to build but if you want to store that energy, you need another 50 CR INR for batteries. x.com/Benarasiyaa/st…
I think it’s better to wait until we have sodium ion batteries less likely to catch fire to go big on in home systems. That’s probably next year or year after. But I understand people moving into the space now.
Lots of storage for a low price, but:
- It’s very heavy (260 kg / 575 pounds)
- It only works with low voltage solar inverters
Any other disadvantages?
Small correction: This is Lithium Iron Phosphate (good for home storage) not Lithium Polymer (not very good for home storage).
Laurie, lithium polymer and lithium iron phosphate are different lithium battery chemistries
For the folks commenting about the fire hazard. I have 30kWh LiFePO4 installed -- it was a consideration.
Name-brand batteries with internal fire suppression from the factory and a good BMS are key
They are in a metal rack in a cement floor room painted with Intumescent paint.
Damn, is there any mid ground brand that is between Ecoflow, Bluetti or Jackery (Amazon) and this that can be bought for a normie? Literally paying same $$ for 10 times less capacity and power…
The missing part is the solar+battery+utility supply/demand monitoring and control that would allow grid balancing.
But US utilities can't even get a grid-tie system to work in island mode because they don't install switches that stop back feeding current during blackouts.
