We will directly check the registration certificate (the big green book) and count the number of changes.

We will carefully check if the chassis number on the windshield, chassis, and door frame matches.

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.
