Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.

Two main shipping methods are used for used cars from China: 1) Container shipping: the car is loaded into a 20ft or 40ft container. Safer, protects from weather and damage, and allows personal items inside the car. Slightly more expensive. 2) RoRo (roll-on/roll-off): the car is driven onto the ship. Cheaper for single units, but no protection and no personal belongings allowed. Typical transit times from major Chinese ports (Shanghai, Guangzhou, Shenzhen, Qingdao): - Middle East: 12-20 days - Europe: 25-40 days - East/West Africa: 30-45 days - South America: 35-50 days - Southeast Asia: 5-12 days Add 5-10 days on each side for port handling, customs, and inland delivery. Peak season (before Chinese New Year and summer) can add delays, so book space 2-3 weeks ahead.

We will provide the transfer record from the vehicle registration certificate. A high number of transfers does not necessarily indicate poor condition (for example, internal transfers within a family for quota purposes), but we will consider it a risk factor and conduct a more thorough physical inspection to verify its actual condition.
