Cheap lithium-ion batteries can look identical on the outside — but be dangerously different inside.

A CT study scanning 1,000 18650 cells found some ultra-cheap brands missing key safety protections and showing serious internal defects — things you cannot see.

I use these cells in my T-Beams. Brand matters.

I’ve worked in fire safety management and training for 28 years. In that time, one hazard has grown from niche to everyday risk: lithium-ion battery fires. These incidents don’t behave like “normal” fires — and that difference is critical for safety. 🧵

@kiwiev.bsky.social shows it best: stab an NMC battery, it erupts. Stab an LFP pack—nothing. That’s why BYD, Tesla & China are shifting hard to LFP. Safer chemistry, no thermal runaway. Battery fires aren’t inevitable—they’re preventable. This isn’t hype. It’s chemistry.🔥 #LFP #EVfire #BatterySafety
