A discharged battery during riding is a frequent issue for electric scooter owners. The battery is a key component of a scooter, however, many people are unaware of how much the battery in an electric scooter lasts and how often to charge it.

An electric scooter allows you to travel a relatively short distance on a single charge. If you are its user, you have surely noticed that the range of your scooter decreases noticeably after a while. Many people regularly replace their equipment with a newer model, which is very expensive. In addition, electric scooters need to be recharged frequently. So how do you effectively increase the range of an electric scooter? The solution to these problems is an additional external battery.
An additional external battery is a battery that you can connect to the primary (internal) battery and mount it outside the scooter (e.g. at the platform). External battery works simultaneously with the primary battery, thus noticeably increasing the range of the scooter. This is more than just a second life for your scooter – it’s like upgrading to equipment 2-3 times more expensive!
Looking for a way to increase the range of your e-scooter? Well you have found the right place! In this article we guide you in choosing the right battery for your current needs.
