The range of IEDs in general increases over time and with technological improvements. This is therefore also the case for electric skateboards. The latter has a variable autonomy depending on the type of model chosen. Once again it is often the longboards that are at an advantage. As they are made for the road, manufacturers often give them more autonomy. Even if today the batteries used on gyroskates are often composed of ION-Lithium allowing an optimal speed of energy transfer allowing to recharge the VEI in only a few hours, the capacity of these batteries remains variable. The average available today is about 15 to 20 km maximum range. However, some more expensive models offer higher autonomy of up to 50 km.  What is quite surprising is that the batteries offered on the majority of electric skateboard models are lower than what is offered for the same equivalent on electric single wheel models for example. The price is often more expensive on electric wheels, but less expensive than the price of a hoverboard, this probably explains this, but the difference in the coming years should be less (some Hummer off-road hoverboard models go up to 20 km/h). The advent of powerful lithium batteries has really helped revolutionize the production of electric skateboards, and almost all new models use them. Of course, some brands still use a classic SLA battery. But the choice will ultimately be based on how you're going to use your machine. You should know that the heavier the skateboard, the more powerful the battery will have to be. And so the electric skateboard will cost more. Also, if you like speed, a very powerful battery, therefore lithium, would be ideal. But of course, the lithium battery does not only have advantages. Compared to SLA batteries, they have shorter battery life. And in terms of lifetime, SLA batteries are much more reliable.
