The battery life of electric skates can also vary depending on several factors, including the capacity of the battery and how the skates are used. Most electric skates can provide a range of up to 20 kilometers (7.5 miles) on a single charge, although this can vary depending on the user's weight, the terrain, and the speed at which the skates are used. The lifespan of electric rollerblades, also known as electric inline skates, can vary depending on several factors, including the quality of the materials and components used, the frequency of use, and how well the skates are maintained. Generally speaking, a well-made pair of electric skates should last for several years with regular use and proper maintenance.
