A 12V 120Ah cylindrical LiFePO4 battery offers durable, efficient, and safe energy storage with long cycle life and fast charging capabilities. Featuring robust cylindrical cells and an advanced Battery Management System (BMS), it is ideal for applications including solar energy, electric vehicles, marine, and backup power, delivering reliable, maintenance-free performance.

What are the technical specifications of a 12V 120Ah cylindrical LiFePO4 battery?

This battery has a nominal voltage of 12.8V and a capacity of 120Ah, providing approximately 1.54 kWh of energy. It supports continuous discharge currents of up to 100A and peak discharge currents up to 150A for short bursts. Typical dimensions are around 328 x 171 x 215 mm, with a weight near 13.3 to 15.6 kg. The battery uses high-quality 3.2V cylindrical cells (21700 or 18650) arranged in a 4S30P configuration, integrated with a smart BMS.

How does cylindrical LiFePO4 technology enhance battery durability and efficiency?

Cylindrical cells offer superior mechanical strength and thermal management compared to prismatic or pouch cells. Their shape facilitates better heat dissipation and structural integrity, reducing risks of thermal runaway and extending cycle life.

What are the common applications of a 12V 120Ah cylindrical LiFePO4 battery?

This battery is widely used in solar energy storage systems, electric vehicles, marine applications, RVs, and industrial backup power systems requiring reliable and efficient energy storage.

How long is the cycle life and expected lifespan of a 12V 120Ah cylindrical LiFePO4 battery?

Typically, the battery delivers over 2000 to 4000 full charge-discharge cycles at 80% depth of discharge, translating to 8 to 12 years of service life depending on usage and maintenance.

What safety features and certifications ensure battery reliability?

Equipped with a comprehensive BMS, the battery protects against overcharge, overdischarge, short circuits, overcurrent, and thermal runaway. It holds certifications such as UL, CE, IEC, UN38.3, and RoHS, ensuring compliance with international safety and environmental standards.

How should a 12V 120Ah cylindrical LiFePO4 battery be charged and maintained?

Charging follows a CC/CV (constant current/constant voltage) method with recommended charge voltage around 14.6V and charge current near 60A. Maintenance is minimal: keep terminals clean, avoid deep discharges, and store in cool, dry environments. Use chargers compatible with LiFePO4 chemistry.

What are the physical size and weight considerations?

Typical dimensions are approximately 328 mm long, 171 mm wide, and 215 mm high, with a weight near 13.3 to 15.6 kg. The cylindrical cell design allows compact packaging and improved thermal management.

How does temperature influence the performance of a 12V 120Ah cylindrical LiFePO4 battery?

The battery operates efficiently between -20°C and 60°C for discharge and 0°C to 55°C for charging. Extreme temperatures can reduce capacity and lifespan, so temperature-controlled charging and storage are recommended.

How does the cylindrical cell design impact thermal management and safety?

Cylindrical cells provide enhanced heat dissipation and mechanical robustness, reducing the risk of thermal runaway and improving overall battery safety and longevity.

What advantages does LiFePO4 chemistry offer in cylindrical cells?

LiFePO4 chemistry delivers high thermal stability, long cycle life, environmental friendliness, and excellent safety characteristics. It supports deep discharge without damage and maintains stable voltage output.

How do you select the right 12V 120Ah cylindrical LiFePO4 battery for your needs?

Consider your application’s voltage and capacity requirements, physical space, discharge current demands, and environmental conditions. Consulting with Lithium-Battery-Manufacturer ensures customized solutions optimized for your specific use case.
