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.

Unauthorized personnel are prohibited from entering and taking photos inside the roll-on/roll-off ship, but we will provide photos of the vehicles parked in the loading area with the ship in the background. The bill of lading marked "Shipped on board" with the date is the most essential legal proof of loading.
