EVE is a well-known manufacturer of lithium batteries, and this range includes cells at two voltage levels: the C40 3.2V 20Ah and the 3.2V 100Ah, plus 3.6V cells in 1200mAh and 3200mAh capacities. A nominal voltage of 3.2V is characteristic of lithium iron phosphate chemistry, which is valued for stability and long cycle life, and the large Ah ratings make these cells suited to energy storage, backup power and electric mobility packs, where they are assembled in series and parallel. The 3.6V cells are typically used in compact devices and electronic equipment. Selecting the right capacity and voltage lets battery-pack builders and equipment makers design for their power needs.
