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.

International wire transfers generally follow "shared (SHA)" or "sender pays all (OUR)" principles. To ensure we receive the full remaining payment to release the bill of lading, we require all buyers to choose the "OUR" option when remitting, covering all intermediary bank fees.

If your market is in extremely cold regions (like Russia or Northern Europe), we strongly recommend purchasing ternary lithium (NMC) models equipped with heat pump air conditioning. The range achievement rate of used LFP batteries typically plummets at minus 15 degrees, and we will alert you accordingly.
