This site only provides pre-purchase risk prompts. SOH, insulation, voltage delta, warranty and repair conclusions should be confirmed by manufacturer systems, professional reports, contracts and official explanations.
Questions to ask
Anchor questions to verifiable records, diagnostic items and written commitments to reduce information gaps.

Displayed range is not SOH, but it is one of the easiest onsite risk signals. Below 80% needs BMS review; below 70% should not be bought on a test drive alone.
Risk guideSOH reflects capacity-health trend; cell voltage delta reflects consistency risk. One number is not enough: review temperature, SOC, fault codes and test-drive behavior.
Risk guideFast charging is not automatically bad, but high share, hot climate, cooling issues and high mileage together should raise the inspection level.
