Everything you need to know about batteries
Are chargers from other manufacturers safe to use?
Booant chargers are adapted specifically to the Booant batteries Using a different charger may reduce the service life of the batteries or cause other damage or malfunctions in the eBike system.
Can Booant batteries be opened to replace individual cells?
Booant eBike batteries must never be opened – not even if they are being repaired by third parties. Opening the battery always means interfering with the condition approved by Booant and entails safety-related risks. once opened, may catch fire during assembly due to crushed or incorrectly routed cables, detached components or poor quality electrical connections.
After opening, the seal of the housing can no longer be guaranteed, so that the ingress of water or dust can lead to damage to the monitoring electronics (Battery Management System) or to the cells.
