LiFePO4 Chemistry
LiFePO4 is the formula name of Lithium Iron Phosphate, also known as LFP. The nominal voltages of this battery chemistry are 3.2V. It replaced other battery technologies because of its technological advancement and safety features. This latest technology is being used in a number of application from small devices consumer devices to heavy duty industrial machines. These cells have high density and light weight which enable this technology to use in multiple devices.Lithium Iron Phosphate Cylindrical Cells
Cylindrical cells one of the most widely used lithium ion battery shapes due to ease to use and good mechanical stability. The tubular cylindrical shape can withstand high internal pressures without collapsing. Melasta produces multiple sizes and capacities according to the customer requirement. These cells are mostly used in Electrical vehicles such as golf cart and in power tools.
