A 12V 20Ah LiFePO4 battery provides reliable and long-lasting power through advanced lithium iron phosphate chemistry, offering over 2000 charge cycles, fast charging, and integrated safety features. Its lightweight, compact design and intelligent Battery Management System (BMS) ensure efficient, safe, and durable energy storage for diverse applications.

What is a 12V 20Ah LiFePO4 Battery and How Does It Work?

A 12V 20Ah LiFePO4 battery is a rechargeable lithium iron phosphate battery delivering a nominal voltage of 12.8 volts and a capacity of 20 amp-hours. It stores energy by moving lithium ions between electrodes during charge and discharge, providing stable voltage and consistent current output for various portable and stationary applications.

How Does LiFePO4 Chemistry Ensure Reliability and Longevity?

LiFePO4 chemistry is thermally stable and chemically robust, minimizing risks of overheating and thermal runaway. It supports thousands of deep charge cycles with minimal capacity loss, ensuring long-lasting, safe, and efficient energy storage.

What Are the Key Features of a 12V 20Ah LiFePO4 Battery?

Key features include:

  • Compact size and lightweight (typically 3-4 kg)

  • High cycle life exceeding 2000 cycles at 80% depth of discharge

  • Integrated BMS for overcharge, over-discharge, short circuit, and temperature protections

  • Wide operating temperature range (-20°C to 60°C)

  • Low self-discharge rate (<3% per month)

  • Durable casing with IP54 to IP65 protection

  • Certifications such as UN38.3, CE, and RoHS

How Long is the Cycle Life of a 12V 20Ah LiFePO4 Battery?

The battery typically offers over 2000 full charge-discharge cycles at 80% depth of discharge, translating to 6-10 years of reliable use depending on operating conditions.

What Applications Are Best Suited for a 12V 20Ah LiFePO4 Battery?
