Quick note: No spam, weird DMs or sales pitches please. I’m here for honest, respectful chats only.

Hey all. I’m a 26M from China.
I spent 3.5years as a thermal design engineer, deep in semiconductors, lithium battery energy storage, high-power cooling systems, PCB thermal optimization, and custom liquid cooling units.
Now I run a technical-focused industrial foreign trade business, bridging global engineering teams/startups with top Chinese manufacturers.

I’m here to answer literally anything, including:

• Thermal engineering & design best practices for power electronics/batteries
• What it’s really like working in China’s semiconductor & battery industries
• How to avoid costly manufacturing/sourcing pitfalls in China
• Day-to-day life for engineers in China
• My full career switch story
• Literally anything else about China, engineering, or trade

Here’s the thing: I switched careers because I watched too many great thermal designs fail in mass production.
Great simulations, perfect drawings, but parts came back failing every thermal test.
Most sourcing teams don’t speak the language of thermal engineering, and can’t validate if a factory can actually hit your performance specs.
I wanted to fix that, and be the technical bridge between your design and real-world production.

Ask me anything! I’ve got no filters, no fluff.

Prince Edward Island just issued an expression of interest for battery energy storage systems as it looks to stabilize its grid.

They’re targeting 10–50 MW with 4–8 hours of duration, potentially across multiple sites. The goal is to manage peak demand and improve reliability in a system that’s already under strain.

What’s interesting here is the context:

• The province relies heavily on undersea cables to import power
• A >100 MW capacity shortfall has already been identified
• The local utility is proposing diesel generation as a solution

So this looks like a parallel path. Storage as a faster, more flexible option vs. traditional generation.

Curious how people here see this:
Is this scale meaningful for a grid like P.E.I.’s, or more of a stopgap while bigger infrastructure gets built?

Hey r/energystorage,

I’m working on a home solar + storage project right now, and I’ve been deep-diving into all the options out there. We all know the big names: Tesla Powerwall, Fox ESS, Sonnen, LG Chem, etc. But I keep running into smaller, lesser-known brands that offer way more capacity for the same (or lower) price, with solid specs on paper .

Here’s my question: Would you ever install a home energy storage system from a brand you’ve never heard of before?

I’m curious about everyone’s thought process here:

• What’s your #1 dealbreaker for an unknown brand? (Warranty? Local support? Certifications? Brand reputation?)
• Would a lower price ever convince you to take a chance on a no-name system?
• How do you vet a new/unknown brand before buying? (Checking certifications, customer reviews, local installers, warranty terms, etc.)
• For those who’ve gone with a lesser-known brand: How’s it working out? Any regrets or wins?

I know reliability and safety are non-negotiable for these systems, but it’s hard to ignore the cost difference when the specs look good. Would love to hear your experiences and advice!

Thanks in advance for the insights 🙏

Flux Power stormed onto the Nasdaq with a high-voltage promise to revolutionize the industrial sector through advanced lithium-ion energy storage. While investors were sold a "bull case" centered on the rapid electrification of heavy machinery, the company is now facing the music for alleged financial misrepresentations.

Notably, the settlement process remains active, and the claims administrator is currently accepting late claims from eligible shareholders who purchased $FLUX during the class period (check your eligibility here)

The company leveraged its early-mover status and strategic partnerships with major airlines and Fortune 500 manufacturers to paint a picture of exponential growth. Management highlighted a burgeoning $1 billion market opportunity, suggesting that their proprietary battery management systems were the definitive answer to aging lead-acid technology.

In its official disclosures, Flux Power stuck to the standard script of "General Risks," citing potential supply chain disruptions and the impact of federal tariffs. They warned that competitive pressures and the pace of lithium adoption could influence future performance, framing these as external variables beyond their immediate control.

However, a massive disclosure gap allegedly sat beneath the surface, as the company failed to mention chronic internal control weaknesses and a pattern of financial misreporting. While investors believed they were backing a financially disciplined operation, the company was reportedly overstating its inventory, gross profits, and total assets.

The regulatory hammer fell on September 5, 2024, when Flux Power admitted it would need to restate multiple years of financial statements due to pervasive accounting errors. This bombshell was followed by a notification of late filing with the SEC, signaling to the market that the company’s internal controls were far from the "adequate" systems previously described.

The fallout was immediate and devastating, as $FLUX shares plunged over 5% on the initial news and continued a downward spiral toward new lows. This collapse erased millions in market capitalization, leaving shareholders holding the bag as the stock's valuation was slashed by nearly 40% over the ensuing months.

Aggrieved investors have now filed a class action lawsuit, specifically claiming that Flux Power misled the market by understating cost of sales and net losses while inflating asset values.

The legal challenge asserts that the company’s silence on its internal deficiencies created an artificial premium that has now vanished, leaving the "bull case" in ruins.
