Your LFP chemistry is identical to CATL's. Your financing terms aren't. BatteryPassport gives you third-party verified field data that eliminates the brand-driven spread premium - so your bid wins on performance, not reputation.
Lender models don't distinguish "proven LFP from CATL" from "identical LFP from unknown assembler." They see brand risk - and price it in. Your datasheets say the same thing. Your financing doesn't.
BatteryPassport certification is bundled into the developer's competitive bid. The developer absorbs the cost in their pro forma. You get the data. They get the deal.
