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.

Vetting takes a day and can save you thousands. Work through this checklist. Verify the business: ask for the company registration number and check it on China's National Enterprise Credit Information system or a commercial registry tool. Confirm the registered address matches where they claim to operate, and that their business scope includes vehicle export. Check export credentials: they must hold a used-vehicle export license issued by Chinese commerce authorities. Ask for the license and a recent export declaration showing they actually ship cars. Test their knowledge: a real exporter answers detailed questions about your destination country's import rules (age limits, left/right-hand drive, emission standards) without hesitation. Vague answers about your own country's requirements are a red flag. Structure payments safely: small deposit (10-20%), balance only against inspection reports and shipping documents, ideally through a payment method with recourse. Refuse full prepayment by irreversible transfer—no legitimate exporter requires it.

RoRo (roll-on/roll-off) is cheaper and faster for a single car—you drive it onto the vessel and it is secured on the car deck. Container shipping costs more but offers better protection from weather, salt air, and handling damage, and allows you to load spare parts inside the car. Marine insurance is essential either way. Standard cover protects total loss and major damage, but read the exclusions: many policies do not cover pre-existing mechanical faults, cosmetic scratches below a deductible, or damage caused by improper securing (lashings). Ask for ICC(A) or All Risks coverage rather than basic total-loss-only policies. Practical tips: 1. Photograph and video the car thoroughly at loading, with the VIN visible 2. Note existing scratches on the bill of lading 3. Inspect immediately at destination—claims windows are often 3-7 days 4. For EVs, declare the battery; some insurers charge a supplement or exclude battery damage altogether
