The 72V 50Ah LiFePO4 battery is a medium-to-large capacity energy storage and power supply product, designed to meet the power demand of equipment that requires stable high-voltage power supply. It adopts mature LiFePO4 cell technology, with stable performance and reliable quality, suitable for multiple professional application scenarios.

　　I. Basic Product Parameters

　　Nominal Voltage: 72V

　　Nominal Capacity: 50Ah

　　Cell Type: LiFePO4 (lithium iron phosphate)

　　Energy Density: Consistent with standard LiFePO4 cell level, ensuring reasonable volume and weight under the premise of capacity.

　　Charge Voltage: 84V (standard constant current constant voltage charging)

　　Working Temperature Range: -20℃~60℃ (discharge), 0℃~45℃ (charge); performance may be slightly affected at extreme temperatures.

　　II. Core Performance Characteristics

　　Safety Performance: LiFePO4 cells have stable chemical properties, with no obvious risk of explosion or fire under normal use. The built-in BMS (Battery Management System) monitors voltage, current and temperature in real time, with overcharge, over-discharge, short-circuit and over-temperature protection functions.

　　Cycle Life: Under 80% deep discharge condition, the cycle life can reach more than 3000 times; the capacity retention rate is not less than 80% after long-term use, which is better than traditional lead-acid batteries.

　　Charge and Discharge Performance: Supports constant current charging, and the charging time is about 8-10 hours under standard charging current; the discharge platform is stable, which can provide continuous and stable power for equipment.

　　Maintenance Requirement: No need for regular water addition or other maintenance operations during use, only need to avoid overcharging, over-discharging and long-term exposure to extreme environments.

　　III. Applicable Scenarios

　　Electric Vehicles: Suitable for medium-sized electric vehicles such as electric tricycles, small electric trucks and some special-purpose electric vehicles, providing stable power support for vehicle operation.

　　Energy Storage Systems: Used in small and medium-sized energy storage scenarios such as off-grid photovoltaic energy storage, small wind power energy storage, and emergency backup power supply, to store and release electrical energy as needed.

　　Industrial Equipment: Matching with industrial equipment that requires 72V power supply, such as small forklifts, electric tools and test equipment, to ensure the normal operation of the equipment.

　　IV. Usage Notes

　　It is recommended to use a dedicated 72V charger for charging to avoid using non-compliant chargers that may damage the battery.

　　Avoid storing the battery in high temperature, high humidity or low temperature environment for a long time, which will affect the service life.

　　When the battery is not in use for a long time, it is recommended to keep the remaining power at 40%-60% and charge it once every 3 months to maintain cell activity.

　　Do not disassemble, puncture or short-circuit the battery to prevent safety accidents.

　　The 72V 50Ah LiFePO4 battery focuses on stability and practicality, and can meet the basic power supply needs of related equipment. It is a cost-effective choice for scenarios that require high-voltage and medium-capacity battery products.
