About this item
  • ⚠️ (note) | Our electric bicycle battery packs can only temporarily withstand high temperatures and slow down the spread of flames and smoke, but they cannot withstand high-temperature flames for extended periods. Therefore, we strongly advise you to call the fire department immediately in case of a fire! Warning: The smoke may contain toxic substances!
  • 🔥【Fireproof and Explosion-Proof Materials】Made with 100% fireproof exterior materials and flame-retardant non-woven fabric lining, capable of withstanding temperatures up to 6200℉. Our lithium battery safety bag has been certified by several reputable organizations and has undergone multiple successful tests by fire departments in real-world scenarios. It prevents the spread of fire, buying you valuable time for rescue efforts.
  • 🧯【10-Layer Thermal Attenuation Structure】This battery bag utilizes eight layers of heat-resistant materials from the inside out, including fiberglass fabric, thermal insulation cotton, aluminum foil, and silicone coating. The unique nested design creates independent spaces between the material layers, continuously weakening heat transfer within the bag and preventing heat from spreading to the outside.
  • ⛱️【360° Protection & Safe Heat Dissipation】The battery safety storage bag is sewn with flame-retardant thread and fire-resistant edging to prevent flames from damaging the fireproof bag from the edges. It also features unique double-sided, dual-color reflective strips for easy visibility in the dark. Three specially designed ventilation holes allow for rapid heat dissipation and the release of toxic fumes. The flap design can withstand high-pressure water jets from fire hoses.
  • 👜【Portable and Convenient】Our lithium battery bag is designed to protect your battery from fire, explosion, and moisture. This bicycle lithium battery safety bag is suitable for various scenarios. It features an ultra-soft hand strap and shoulder strap for easy lifting and carrying, and side openings allow for safe charging without opening the bag.
  • 📧【A Perfect Gift】This fireproof battery bag is an ideal gift for friends, family, loved ones, and customers. For any product-related questions, please contact us: 1. Go to your "Your Orders" page and click the "Contact Seller" option; 2. Click "Ask a question" on the store page. We will reply to you within 24 hours.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
