Additionally, it is important to store the battery in a dry and isolated environment to avoid excessive pressure and keep it out of reach of children.

Our battery is perfect for 500w – 2000w motors, providing an estimated range of 15 – 40 miles on a single charge (depending on motor power). And with all waterproof connectors, you can rest assured that your battery will stay protected from the elements.
