Using an external battery for your electric scooter allows you to increase its range. The external battery is equipped with a BMS that manages charge control, discharge, and cell balancing. Before purchasing your external battery, it is important to know which type of battery corresponds to your scooter. Weebot tells you more.
How to choose an external battery?
Choosing an external battery for your electric scooter is not done randomly. Several criteria must be taken into account to ensure compatibility, performance, and safety. Here are the three essential elements to consider before making your choice.
1. Check technical compatibility with your scooter
First of all, it is crucial to ensure that the external battery is perfectly suited to your vehicle. This involves several technical points, including:
-
The type of battery: prioritize lithium batteries, known for their reliability, lightness, and longevity.
-
The power circuit: the chosen external battery must be compatible with that of your scooter. A poor match can lead to performance loss or even risks to the electronics.
-
The voltage: for optimal operation, the external battery must have the same voltage as the internal battery of your scooter. A voltage difference could damage electrical components or harm the range.
2. Choose a capacity suited to your needs
The choice of your electric scooter battery should also depend on the use you plan:
-
For short trips in the city, a battery with moderate capacity may suffice.
-
However, if you plan long trips or regular rides, opt for a more autonomous battery, capable of covering a significant distance without recharging.
-
Also consider size and weight: a more powerful battery is often bulkier. You need to find the right balance between performance and practicality, especially if you need to carry it or attach it easily.
3. Buy from trusted sites to avoid counterfeits
Finally, a criterion often overlooked but essential: the origin of the battery. It is strongly recommended to buy your external batteries from specialized and trusted sites, like Weebot, to avoid counterfeit or uncertified products.
A poor-quality battery can cause overheating, rapid discharge, or even pose a danger to the user.
And to combine safety and practicality, Weebot provides you with a waterproof bag with every external battery purchased, to protect it effectively from shocks and bad weather during your travels.
