It rarely happens, but there is a clear mechanism. If the transaction is canceled due to our reasons (such as the vehicle being suddenly seized by judicial authorities during the transfer), we will refund the full deposit you have paid and provide additional compensation according to the penalty clauses in the contract.

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.

All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.
