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.

It depends on the car's value, type and destination. RORO means the car is driven onto the vessel and secured on deck or in the hull. It is usually cheaper per car and does not involve container packing fees. The downside: the car sits exposed to salt air for weeks, and RORO service is limited to ports with dedicated terminals. Container shipping (one 20ft or 40ft container per 1-2 cars) costs more but gives much better protection. It is strongly recommended for electric vehicles (battery safety regulations), luxury cars, and vehicles going on long voyages or rough sea routes. Practical tips: whichever method you choose, ask for the car to be shipped with a full battery charge disconnected at the terminals, tire pressures adjusted, and a condition report with photos signed at loading. For EVs, confirm the shipping line accepts used electric vehicles and what state-of-charge limits apply.

Yes. If your country (such as Chile, Peru, ASEAN countries, etc.) has signed a bilateral free trade agreement with China, our documentation center will apply to Chinese customs or the trade promotion agency for specific versions of the certificate of origin (such as Form E, Form F, etc.), which can help you legally apply for significant tariff reductions at the destination port.
