Battery & range

Gross capacity
8.7 kWh
Chemistry
LFP
LFP — Lithium iron phosphate
  • Longest lifespan — the most charge cycles before it fades
  • Safest chemistry; very stable under heat or damage
  • Fine to charge to 100% every day
  • No cobalt or nickel, so cheaper to build
  • Less range for the same size and weight
  • Loses more range in cold weather
  • Slower DC fast-charging when cold

Questions for the seller (2)
  • Battery health report The seller can pull one from the car; it's the only real degradation data, and nothing remote can measure it.
  • Build date (door-jamb sticker) and original in-service date Settles mid-year running changes; the in-service date, not the model year, starts the warranty clock.
