Application for 2200mAh 18650 LiFePO4 battery
This 3.2V 2200mAh 18650 LiFePO4 battery is suitable for compact devices that need safer LFP chemistry, moderate discharge capability, and a cylindrical cell format, including solar garden lights, emergency lighting modules, IoT sensor nodes, wireless communication modules, portable instruments, barcode scanners, small backup power boards, and compact field measurement tools. Its 18.6mm x 65.2mm cell size fits common 18650 holders and custom pack layouts, while the 0.5C charging current and 3C maximum discharge rating support many low-voltage industrial and commercial electronics without positioning the product as a high-drain power-tool cell. VTCBATT can customize battery solutions by matching holders, nickel tabs, protection circuit design, wire length, connector type, NTC configuration, labels, and packaging, with factory-direct battery wholesale support for distributors, equipment brands, and OEM manufacturers.
VTC18650-2200mAh-3.2V LiFePO4 Cylindrical Battery Cell
The VTC18650-2200mAh-3.2V is a 3.2V 2.2Ah LiFePO4 18650 battery cell for compact rechargeable equipment, backup modules, sensor platforms, solar-powered devices, and OEM battery pack development. This article is based on the local parameter sheet, selling-point notes, model comparison table, and product images available in the project folder.
Product Overview
This cell uses Lithium Iron Phosphate chemistry in a standard 18650 cylindrical format. The local product notes position it as a lightweight, high-performance, safe and reliable LFP battery cell, while the model table identifies the target item as VTC18650-2200mAh-3.2V (18FC-7.04Wh).
Core Electrical Parameters
The cell has a nominal voltage of 3.2V and a nominal capacity of 2.2Ah. The model list gives 0.5C charging current, 3C maximum discharge current up to 6.6A, and internal resistance of no more than 25mOhm. These values make the cell suitable for many moderate-current electronics, rather than unsupported high-drain claims.
