With 153.6Wh of usable energy, this powerhouse is engineered to seamlessly replace lead-acid batteries in UPS systems, security equipment, emergency lighting, medical devices, and portable electronics.

Built with premium LiFePO4 cells, an intelligent Battery Management System (BMS), and housed in a durable ABS+PC enclosure with IP55 protection, the YF12120-LFP offers superior safety, exceptional cycle life, and true maintenance-free operation. For distributors, system integrators, and brands seeking a reliable partner, Yunfan Factory provides comprehensive OEM/ODM capabilities to bring your customized battery solutions to market with speed and precision.

• Direct Drop-In Replacement - Higher Capacity, Same Footprint: With standard 12.8V nominal voltage and identical dimensions (151*65*94mm) to common 12V 7Ah-12Ah lead-acid batteries, the YF12120-LFP offers a true plug-and-play upgrade. Your customers get double the usable capacity without redesigning their existing systems.
• Exceptional 5,000-Cycle Lifespan: Rated for ≥ 5,000 cycles at 0.3C charge/discharge, this battery outlasts lead-acid by 5 to 10 times, translating to fewer replacements and superior long-term value.
• Intelligent BMS with Comprehensive Protection: The integrated Battery Management System delivers full protection against overcharge, over-discharge, over-current, and short circuits with active cell balancing for optimal performance.
• Robust Construction for Demanding Environments: Housed in durable ABS+PC enclosure with IP55 protection, the YF12120-LFP withstands dust and low-pressure water jets while weighing only 1.4kg.
• High Power Output for Demanding Applications: With 12A maximum continuous discharge current and 12A peak charge current, this battery handles higher loads than standard alternatives.
• Wide Operating Temperature Range: Functions reliably in discharge temperatures from -20°C to 60°C, ensuring consistent performance across diverse environmental conditions.
• Globally Certified for Market Readiness: Fully certified with UN38.3 and MSDS, ready for safe international transport and meeting global market safety requirements.
