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.

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.

As the importer, you mainly need to bear the following costs at the destination port: import duties, VAT or GST, terminal handling charges, local customs clearance fees, and inland logistics costs from the port to your company. Please consult your local customs broker before placing an order to accurately calculate the total landing costs.
