June 17, 2026 — An incident report details a dangerous malfunction with an Aniioki A9 Pro Max electric bike battery, which began emitting smoke upon its first charge, posing a significant fire risk. The consumer, fortunately uninjured, was then illegally pressured by the online retailer and third-party seller to return the hazardous battery via standard commercial carriers.
Product Details
Product: Aniioki A9 Pro Max
Incident Overview
The incident occurred when a family member of the purchaser plugged the lithium-ion battery of their newly acquired Aniioki A9 Pro Max electric bike into its charger for the very first time. Shortly after plugging it into a standard outlet, the battery began to emit smoke. The user immediately unplugged the battery, preventing a potential fire or explosion.
While there were no injuries reported, the incident presented a severe risk of a catastrophic house fire, indicating a critical thermal and fire hazard with the e-bike battery. The consumer reported this incident due to the inherent danger of the product.
Adding to the consumer’s distress, when attempting to return the defective product, the online retailer (Amazon) and the third-party seller reportedly demanded that the smoking, damaged lithium battery be shipped back via standard commercial carriers. This demand is a direct violation of US Department of Transportation (DOT) regulations for hazardous materials, which prohibit the shipment of damaged or defective lithium batteries without proper Hazmat handling and documentation. The sellers allegedly refused to provide a safe, Hazmat-compliant freight pickup, effectively trying to compel the consumer to illegally ship a known fire hazard.
Safety Concerns
This incident presents multiple serious safety concerns:
- Immediate Fire and Explosion Hazard: The primary concern is the potential for the lithium-ion battery to overheat, catch fire, or explode. Lithium-ion battery fires are extremely dangerous, difficult to extinguish, and can spread rapidly, releasing toxic fumes.
- Property Damage Potential: A battery fire inside a home could quickly lead to extensive structural damage, destruction of personal belongings, and even render the home uninhabitable.
- Risk of Injury or Death: While no injuries occurred in this specific incident, such fires pose a severe risk of burns, smoke inhalation, and potentially death to occupants of the home or anyone nearby.
- Hazardous Materials Shipping Violation: The demand from the retailer/seller for the consumer to ship a damaged lithium battery via standard carriers is a significant safety and legal concern. Shipping damaged lithium-ion batteries without proper Hazmat procedures is illegal, extremely dangerous, and puts package handlers, transportation personnel, and the public at risk of fire or explosion during transit. It highlights a dangerous lack of awareness or disregard for hazardous material regulations by the sellers.
What Consumers Should Do
If you own an Aniioki A9 Pro Max electric bike or any product with a lithium-ion battery:
- Immediately Discontinue Use: If your Aniioki A9 Pro Max battery shows any signs of overheating, swelling, smoke, or unusual smells, immediately stop using it, unplug it from the charger, and move it to a safe, non-combustible outdoor area, if safely possible. Do not attempt to charge or use it again.
- Do Not Attempt Illegal Returns: If you encounter issues with a smoking, damaged, or defective lithium-ion battery, DO NOT attempt to ship it back via standard mail or parcel services as directed by a retailer if they do not provide Hazmat-compliant shipping. Inform the seller that this violates DOT regulations and demand a safe, compliant return method, such as a specialized Hazmat pickup.
- Battery Safety: Always use the charger specifically provided with your e-bike. Do not overcharge batteries or leave them charging unattended for extended periods, especially overnight. Store batteries in a cool, dry place away from direct sunlight and flammable materials.
- Check for Recalls: Stay informed about potential recalls or safety alerts for e-bike batteries and related products.
- Report Incidents: If you experience a similar incident with a product, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report helps identify dangerous products and prevent future harm.
