32700 LiFePO4 battery is a common type of cylindrical lithium-ion battery, with a designation that intuitively reflects its physical dimensions: a diameter of approximately 32mm (actual range: 32.0–32.5mm, accounting for heat-shrink wrapping or steel casing tolerances) and a height of approximately 70mm (excluding the positive terminal protrusion or protection board; 70.3–71mm including terminal markings or posts), with the final digit “0” indicating its cylindrical shape.
Compared to the common 18650 (18×65mm) and 21700 (21×70mm) formats, the 32700 has a significantly larger volume, resulting in substantially higher individual cell capacity and power potential. As a large-format cylindrical cell, the 32700 is widely used in applications such as energy storage systems, power tools, and light electric vehicles.
NBCELL’s 32700 cylindrical cells utilize Lithium Iron Phosphate (LiFePO₄) chemistry, offering features such as safety and stability, long cycle life, and flexible battery pack customization options.
