We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.

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.

No, we are not responsible. The high salt and humidity of the marine environment do have an impact on the chassis surface. We recommend buyers in tropical islands or countries that use salt for winter snow removal to perform a thorough chassis anti-rust spray locally immediately after the vehicle arrives.
