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.

The "usage type" section on the vehicle registration certificate has legal validity. Any vehicle that changes from "commercial" to "non-commercial" has a usage intensity far exceeding that of personal vehicles, and we will label these prominently. Such vehicles are usually cheaper but have more severe mechanical wear.

Typically you will need: 1. The commercial invoice and packing list from the seller; 2. The bill of lading issued by the shipping line; 3. The vehicle's export customs declaration; 4. The original registration certificate and a deregistration or transfer proof from China; 5. A certificate of origin if your country requires it; 6. Destination-specific documents, such as a pre-shipment inspection certificate (for example ECTN for West African ports). Requirements vary by country, so confirm the full list with your customs broker before shipment.
