Overview

The Lishen LR2170SF is a genuine Li-ion cell with a nominal capacity of 4.5Ah at 3.65V, giving 16.4Wh of energy per cell.

About this chemistry

Lithium-ion cells with nickel-based cathodes (NMC, NCA and similar) have the highest energy density of all the chemistries we offer. Cylindrical 18650 and 21700 cells are used in e-bike, e-scooter, power tool and portable batteries. Nominal voltage is 3.6–3.7V per cell and the charge voltage is usually 4.2V. Choose high-capacity cells for range, or high-drain cells for power.

About this format

Cylindrical cells have a steel can and are named after their size: the first two digits give the diameter and the following digits the length in millimetres (for example, 18650 = 18mm × 65mm). They are robust and consistent, and well suited to packs built with spot-welded nickel strip or cell holders.

Typical applications

E-bikes and e-scooters, power tools, portable power stations, torches, drones, robotics, and custom packs where weight and size are critical.
