Overview

The Tenpower IFR26700-40HE is a genuine LiFePO4 cell with a nominal capacity of 4Ah at 3.2V, giving 12.8Wh of energy per cell.

About this chemistry

LiFePO4 (lithium iron phosphate, LFP) is the most widely used chemistry for stationary storage and deep-cycle batteries. It is thermally very stable, contains no cobalt or nickel and typically lasts thousands of cycles. Each cell has a nominal voltage of 3.2V: four cells in series make a 12.8V battery, eight make 25.6V and sixteen make the 51.2V used by most home storage inverters.

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

Home and commercial energy storage, off-grid solar systems, campervans and motorhomes, boats, golf carts and light electric vehicles, telecom backup, DIY battery packs.
