Notes on Techfine Products

• Techfine’s official battery lineup includes 48 V LiFePO₄ packs up to ~14 kWh (300 Ah) and similar variants with LiFePO₄ cells and BMS features, but no specific “Techfine 16 kW 48 V REPT” PDF was publicly found on their website as of now.

• It’s possible that “REPT cell” refers to the cell manufacturer grade/type used inside such LiFePO₄ modules — similar to what some suppliers use (e.g., REPT, CALB, CATL, EVE).
