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 hidden fees. The total amount on the FOB/CIF invoice is the final amount. We rely on professional supply chain operations to earn a reasonable margin and do not allow any sales personnel to privately request kickbacks or service fees from you.

Our legal delivery milestone is based on the "Estimated Time of Departure (ETD)". As long as the vehicle enters the port area and customs clearance is completed within the agreed timeframe, any delays in shipping schedules due to the shipping company's capacity adjustments will not be considered a breach on our part. The uncontrollability of maritime transport must be factored into your expectations.
