We understand that the power battery is the core asset of an EV. Before export, our technical team will use professional OBD diagnostic equipment to read the underlying data from the Battery Management System (BMS). We will provide you with a technical report that includes key indicators such as battery health percentage (SOH), cell pressure differences, and charge-discharge cycle counts. If the SOH is below our established export safety standard (usually above 80%, depending on the vehicle's age), the vehicle will be intercepted and not sent overseas.

If the delays are due to policy-related force majeure like customs system upgrades, or if our documentation errors lead to short shipments, all additional demurrage and storage fees incurred at ports within China will be borne by sellwellauto, and the buyer will not have to pay a cent.

Most models adjust through the central control screen menu, while a few models (like some BYD or MG) retain physical levers or paddles on the center console or steering wheel. We will check if the drag feel when the system engages is linearly normal.
