When sourcing BYD vehicles, the most critical component is the Blade Battery technology, which utilizes Lithium Iron Phosphate (LFP) for superior thermal stability and safety. Buyers must verify the NEDC or WLTP range to ensure it meets local market expectations. Additionally, check the charging port standard (e.g., GB/T, CCS2, or Type 2) to ensure compatibility with the destination country's infrastructure, and confirm the presence of the DiLink intelligent network system for software localized to your region.
