Sydney’s lithium-ion battery fire crisis has reached a tipping point. In just 12 hours, Fire and Rescue NSW (FRNSW) raced to four separate e-scooter explosions—injuring residents, shattering windows, and leaving firefighters scrambling to contain the fallout.
The message from authorities is clear: modifying e-scooters or using unapproved chargers isn’t just risky—it’s life-threatening. Here’s what you need to know to protect yourself, your home, and your community.
The Incidents: A 12-Hour Firestorm

On February 6, 2025, FRNSW crews faced one of their most chaotic mornings yet:
- Sadlier Explosion: A modified e-scooter battery erupted in flames at 7:40 AM, injuring two men—one struck by shrapnel, the other burned and overcome by smoke.
- Granville DIY Disaster: A homemade battery pack for an e-bike ignited in a unit, forcing neighbors to evacuate.
- Parramatta and Canley Vale Blazes: Two additional fires linked to mismatched chargers and tampered devices.
These incidents contributed to 11 battery-related fires in NSW in just four days, underscoring a grim reality: cheap modifications and DIY repairs are fueling a preventable crisis.
Why Modifications Are a Ticking Time Bomb
1. The “Mix-and-Match” Menace
Using mismatched chargers or third-party batteries bypasses critical safety protocols. As FRNSW Superintendent Adam Dewberry warned, “People are not only repairing devices but making their own batteries. It’s extremely dangerous”.
Lithium-ion batteries rely on precise voltage and temperature controls. Unapproved components can overheat cells, triggering thermal runaway—a chain reaction that releases toxic fumes and explosive energy.
2. The Hidden Cost of Cheap Gear
Discounted or secondhand batteries often lack safety certifications. In 2023, FRNSW and Fair Trading identified 40 faulty e-scooters sold online—many with water damage or substandard parts. These devices are “ticking time-bombs,” says FRNSW Assistant Commissioner Trent Curtin.
3. DIY Culture vs. Professional Expertise
While YouTube tutorials make battery repairs look easy, FRNSW stresses that only qualified professionals should handle lithium-ion systems. Over 35% of 2024’s micromobility fires involved DIY modifications.
How to Charge Safely (and Avoid Becoming a Statistic)
FRNSW’s safety guidelines are non-negotiable. Here’s your action plan:
1. Buy Reputable, Certified Gear
- Look for the Australian Regulatory Compliance Mark on chargers.
- Purchase devices meeting AS/NZS 60335.2.114:2023 or UL 2272 standards.
2. Charge Like a Pro
- Never charge overnight or in bedrooms. Opt for open areas like garages (away from exits!).
- Use only the manufacturer’s charger. As FRNSW notes: “Just because the plug fits doesn’t mean it’s compatible”.
- Stop charging once the battery hits 100%.
3. Spot (and Stop) Danger Early
Red flags include:
- Swelling, leaking, or cracked batteries.
- Hissing sounds or smoke.
- Overheating during use or charging.
If your device malfunctions:
- Move it outdoors (at least 3 meters from structures).
- Call Triple Zero (000)—never attempt to extinguish lithium fires yourself.
NSW’s Crackdown: New Laws to Curb the Crisis
Starting February 2025, NSW enforces stricter safety standards for e-scooters and e-bikes:
- Mandatory certification: Devices must pass testing by accredited labs (e.g., AS 15194 for e-bikes).
- Penalties: Corporations face fines up to $825,000 for selling non-compliant products.
- Transparency: Retailers must provide safety guides covering fire risks, charging, and disposal.
FRNSW and Fair Trading are also collaborating with food delivery giants like Uber Eats and Zoomo to educate riders on safe practices.
Community Response: “We Can’t Afford to Wait”
After the Sadlier explosion, local resident Mark Thompson shared: “I heard what sounded like a firecracker—then screams. This isn’t just about rules; it’s about keeping our streets safe.”
Meanwhile, industry leaders like Zoomo CEO Mina Nada are pushing for awareness: “Illegal bikes with unsafe batteries are the number one risk. Riders often don’t understand the dangers”.
Your Next Steps
- Audit Your Gear: Check chargers for compliance marks. Replace damaged batteries immediately.
- Spread the Word: Share FRNSW’s safety resources with friends and family.
- Stay Informed: Track NSW’s 2025 safety standards rollout.
Final Thought
E-scooters and e-bikes are here to stay—but their safety depends on you. As FRNSW Commissioner Jeremy Fewtrell warns: “We don’t want to repeat the tragic losses seen overseas. Heed the warnings before it’s too late”.
