How to Source Custom EV Battery Packs from China: A Practical Buyer Checklist

Direct Answer

To source custom EV battery packs from China, buyers should provide vehicle type, voltage, capacity, dimensions, connector, charger, BMS communication, target market, certification requirements, sample quantity, and annual volume. They should also request specifications, certification scope, factory test records, labels, packaging, and validation samples before mass production.

Key Takeaways

  • Clear specifications reduce quotation errors and sample delays.
  • MOQ and lead time depend on housing, cells, BMS, tooling, certification, and documentation.
  • Buyers should verify samples before mass production.
  • Export projects need packaging, label, document, and target-market compliance review.
