The components in the battery compartment are very sensitive. In particular, contact with the battery can be life-endangering due to high voltage. This is why the battery compartment is sealed with waterproof insulation. If you open the battery compartment, this will damage the seal and your scooter will no longer be waterproof. Furthermore, you may unintentionally damage the components, endangering the operational safety of the scooter. We can therefore accept no liability for damage to the scooter when the battery compartment has been opened without authorization. To open the battery compartment, contact your EGRET dealer (link?) or get in touch with our customer service.
