NEWS: BYD has launched its next-generation battery energy storage system. It has a unit capacity of 14.5 MWh, the highest globally to date. The energy storage system achieves an ultra-large capacity of 10 MWh within a space equivalent to a 20-foot container, BYD said. For a 1 GWh storage... plant, it will cut the number of required units by more than half, reduce land use by one-third, and trim cell count by 76%, according to the manufacturer. It uses BYD’s self-developed 2,710 Ah Blade Battery cell, which the company claims is the largest energy storage cell in the world. "This next-generation cell delivers three times the capacity of conventional storage batteries, boasts a cycle life of over 10,000 cycles, and reduces the total lifecycle cost per kilowatt-hour to below $0.014 – a milestone that could reshape the economics of large-scale storage." BYD says it can cut project-level levelized costs (LCOS) by 21.7%. For a typical 1 GWh installation, total costs related to equipment procurement, transportation, and installation are expected to drop by around 30%. In addition, BYD has launched its new GC Flux grid-forming inverter solution, which covers the 2.5–10 MW capacity range. According to BYD, the inverter boasts a performance level approximately 38% higher than common industry standards and a maximum power density of 1,474 kW/㎡, which is around 130% above typical values in today’s market. The system provides an overload capacity of up to 3x for 10 seconds and reaches a peak efficiency of 99.35%.show more

BYD vs MegaBlock comparison

per GPT5:

You might want to give some context rather than these misleading marketing numbers direct from a breathless press release. They advertise high inverter efficiency whereas Tesla correctly gives system round trip efficiency. BYD’s number is akin to saying you’ve got really efficient transistors. Irrelevant. They boast a huge MWh number, but such a pack cannot be transported conventionally and/or will need to be assembled onsite. Tesla’s system is fully factory assembled and transportable. And so on. Comparing these ESS systems is complex and I don’t fault you for NOT doing the comparison since that’s better left to a true expert in the field (which there are very few), but rather than regurgitate PR numbers, maybe just say that BYD just released their answer to the Tesla Megablock and that there are several companies in this fast growing industry. BTW, Tesla is at a structural disadvantage to BYD and CATL in this industry since these competitors also manufacture battery cells which is by far the biggest cost item in ESS. However, Tesla has just started manufacturing their own cells for ESS (near GF-1 in Nevada), and probably has a lead in ESS systems architecture and software. Tesla will no doubt be leaning on their German Grohman subsidiary to build automation for LFP battery cell factories in Europe and China, which will be needed to compete in the coming years.

China ripped off Tesla, and will sell them with huge subsidies from the Chinese Communist Party. This is bad.

Dude can you stop advertising for BYD.

@CJ_h04 Me: Posts two pieces of news about BYD. You: cAn yOu StOp AdVeRtIsInG fOr ByD. As my bio has stated for a LONG time, I cover EV/space/tech news.

Fine to make up i will sub to him. This make me bullish for $tsla 🚀🚀

@CJ_h04 Thanks 😂

Tesla is the only company that matters right now.

If anyone else than China buys this they are idiots! In case of a conflict with China, I’m sure they can switch it off remotely, harming the infrastructure in that country!

So Byd is truly the knockoff Tesla?

Wow… this is a full generation ahead of Tesla

way better than Tesla's offerings

Is energy density a big concern with energy storage systems? I was under the impression that it was pretty far down the list of things to care about.

Is BYD going to make a humanoid robot too? Maybe open a diner?

Cool

Are they state sponsored/subsidized?

$TSLA can’t compete with BYD or CATL in batteries

Stop with the China propaganda. It’s always Tesla knock off tech attempting to imply they’re innovative. Plus none of this stuff really gets audited, it’s pumped and then we hear zero adoption or ghost sales.

BYD just launched the world’s most powerful storage unit: 14.5 MWh per box, LCOS < $0.014/kWh, 10,000+ cycles. They don’t just sell batteries anymore, they’re building energy sovereignty. The East doesn’t need your grid anymore. The West still needs its permits. 🔋 Storage is the new oil. 🧠 Who owns the energy protocol? → Thoughts? 👇 #JanusProtocol #BYD #EnergyWar

2,710 Ah is huge.

The comments are hilarious. I genuinely believe that for 80% of Sawyer’s readers this is the first time the penny dropped on Chinese battery manufacturers. It should be no surprise to anyone that if Tesla buys all their batteries from CATL or BYD eventually they can’t compete.

I wonder how heavy this will be to gave that much energy density? Could it exceed the weight for shipping and trucking? My understanding was this was a real limiting factor, the shipping unit maximum was something like 80k pounds.

I only remember BYD saying their cars can run on two wheels, but in reality, both quality and technology are terrible—don’t believe BYD’s propaganda lies.

@grok how does BYD new next-gen battery storage compare with Tesla's new megablocks next gen battery storage?

We have been seeing these amazing battery advancements announced for several years, but nothing ever comes. If BYD can actually bring this to market, it will be a large hurdle for Tesla to overcome.

@grok since when has BYD been copying what Tesla does?

So, BYD is not gonna stop at just EVs when it comes to competing with Tesla !

BYD just has a serious brainpower advantage over everyone. As of last Dec they have 110 000 engineers working on R&amp;D.

@Grok compare this BYD product with recently launched Tesla block.

It's good to see new battery storage innovations announced. The key is always reliable, large-scale deployment, and Tesla has shown consistent leadership here with the Megapack. It will be interesting to see how these new systems perform in critical grid applications over time.

This is one area i don't mind BYD copying Tesla the more the merrier

Does BYD have any different ideas other than copying everything Tesla does? 🤔 Chinese govt pours money in BYD so they can undercut tesla. What do they have in return? Imagine a car spy on people with its cameras is sold worldwide and send datas back to a cunning socialist govt

RIP $TESLA

This completely blows away Tesla megablock/megapack stats I. A space of a megapack BYD delivers a 50% of a megablock, they are just killing it here.

I like megablock more

How long till wind towers are profitable without subsidies? I work in a field where we have to do heavy lift repairs and we have a competitor in the area and we stay hooked up. Cranes aren’t cheap…. There’s no way it’s profitable
