WATTNINE 14.6V 5A LiFePO4 Battery Charger for 4S LFP Battery Pack – 75W Table-Top Charger with CC & CV is designed for charging four-cell series-connected lithium iron phosphate (LiFePO4/LFP) battery packs with a nominal voltage of 12.8V. It provides a regulated 14.6V DC output at 5A and uses Constant Current (CC) and Constant Voltage (CV) charging modes to manage the charging process. The table-top switching power supply design includes LED indicators for charging status and protection against output overload and short circuits. It is suitable for compatible 4S LFP battery packs used in portable power systems, energy storage, and other battery-powered equipment.
