Before You Select a Platform
How do I choose an E-bike battery enclosure?
Start with the available frame space, mounting interface, motor-system voltage, and discharge-current requirement. We confirm cell layout, BMS, connector, and fit before quotation.
Can an existing platform be customized?
Yes. Existing platforms can be configured around cell selection, BMS settings, connectors, labels, and packaging. New enclosure tooling is reviewed as a separate custom project.
Need a Different Battery Configuration?
Start with a proven enclosure or send your frame, electrical, BMS, connector, label, and packaging requirements for review.
