With a built-in 50A BMS supporting 50A Max. Battery management system not only controls the charging and discharging of the battery, but also the temperature to ensure safety, protects the battery from damage such as:over or under voltage/over current/ high temperature/short circuit.
5:12V 50AH Lithium LiFePO4 Battery Wide Usage: Replacing Most of Backup Power, Home Energy Storage and Off-Grid. Usage for air pump, fish finder, golf car, trolling motor, RV & camper, Houseboat, Travel Trailer, Dump Trailer and more. When the batteries are used in parallel or series, the battery voltage and capacity must be the same.12V 50Ah Lithium LiFePO4 Battery Built-in 50Ah BMS, Up to 8000 Deep Cycles Lithium Iron Battery. When the battery is used alone, it can be used directly. When the battery needs to be used in parallel or in series, each battery shall be fully charged according to. The standard charging method before parallel or in series. When long-time storage, the battery SOC is 30% 50%, if high-SOC storage will accelerate the battery capacity degradation. The battery need to be charged every 6 months if out of use. No fall down, no pile up over 10 layers, and keep face up. 12V 50Ah Lithium LiFePO4 Battery Built in BMS, 10 Years Lifetime 4000+ Cycles Output Power 640W. 12V 50Ah LiFePO4 Battery Curves. 12V 50Ah LiFePO4 Lithium Battery. 12V 100Ah LiFePO4 Lithium Battery. 12V 200Ah LiFePO4 Lithium Battery. 24V 100Ah LiFePO4 Lithium Battery.
