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 customs of the destination country has the right to disregard the commercial invoice and reassess the value based on its internal database (such as the customs valuation red book).

It depends on the specific brand and model. Some brands (like BYD and MG) have native multilingual systems that can switch to English directly; however, some models designed for the Chinese domestic market only have a Chinese interface. For systems that only have Chinese, we can assist with compliant system flashing (installing international firmware) or adding modules that support Apple CarPlay/Android Auto, so you can use Google Maps. The details page will clearly indicate the language status of each vehicle's system.
