Q: How to tell genuine Grade‑A Lishen lifepo4 cells apart from Grade‑B / refurbished units?
A: Genuine Grade‑A cells have complete batch serial‑number traceability, tight tolerance on OCV, capacity and AC internal resistance. Grade‑B/refurbished units show large parameter deviation, cosmetic scratches or swelling. We supply only factory‑new Grade‑A cells.
Q: Do I have to use a BMS with Lishen LiFePO4 cells?
A: Yes, a compatible BMS is mandatory for all Lishen lifepo4 cells. It protects cells against over‑charge, over‑discharge, over‑current and over‑temperature. Single bare cell has no built‑in protection circuit.
Q: Do you offer OEM & ODM custom battery packs built from Lishen lifepo4 cells?
A: Yes. We support both OEM and ODM services based on genuine Lishen prismatic lifepo4 cells.
Q: Does your DDP quotation for Lishen lifepo4 include all duties, VAT and customs fees?
A: Our standard DDP quote covers normal import duty and VAT for regular commercial addresses.
