Reputable e-bike suppliers incorporate numerous safety features and thoroughly test their batteries, so the fire risk for good quality e-bike batteries bought from a reputable source is extremely low. Even so, it’s still very important to follow the instructions for charging and storing your e-bike battery. Batteries contain complex materials, including flammable electrolytes, which are great for storing energy but which need to be handled with care and disposed of responsibly. If a battery gets too hot or is damaged, it can cause a rapid rise in temperature, which could lead to a fire. Improper use, unauthorised repairs, using non-genuine parts or using the wrong charger will significantly increase this risk.
