26700 lithium cell — Ø26 × 70 mm cylindrical cell

The 26700 (Ø26 × 70 mm) is a large-format cylindrical cell that packs far more energy into a single can than the 18650 or 21700 — fewer cells per kilowatt-hour, simpler pack architecture and lower assembly cost. We offer it in both NCM and LiFePO4 chemistry, with rated capacities from roughly 5000 mAh to 9000 mAh.

NCM or LiFePO4?

Choose NCM (prefix INR) for the highest energy density and weight savings; choose LiFePO4 (prefix IFR) for the longest cycle life and the best thermal stability — the preferred chemistry for deep-cycle storage. The suffix marks the cell type (D high-power, E energy-storage, P high C-rate). Full specs — weight, internal resistance, charge/discharge rates and cycle life — are in the table above and the datasheet.

Typical applications

The 26700 is well suited to energy-storage systems and high-endurance drones & UAVs. For deep-cycle LiFePO4 storage you may also want to compare it with the 32700 and 32750.
