YUNFAN ES12-200 (YF12V200Ah-LAS) is a high-performance 12.8V 2560Wh lithium iron phosphate battery designed for 0.5C fast charge and discharge—fully charging in just 2 hours and delivering consistent 100A power output. Built with automotive-grade LiFePO4 cells and an integrated intelligent BMS, it eliminates the safety risks, short lifespan, and slow charging of traditional lead-acid batteries. With 5000+ deep cycles and IP55 protection, it is the ideal drop-in replacement for lead-acid batteries in RVs, solar systems, marine vessels, and UPS backup power. Its lightweight design (22kg) and standard Group 8D form factor make installation seamless, while the built-in BMS ensures overcharge, overdischarge, and short-circuit protection for reliable long-term operation.
Features:
0.5C Fast Charge & Discharge: Fully charges in 2 hours; delivers stable 100A continuous power for high-demand applications
Safe LiFePO4 Chemistry: Non-toxic, non-flammable, and thermally stable—no risk of thermal runaway
Intelligent BMS Protection: Prevents overcharge, overdischarge, overcurrent, and short circuit; automatically balances cells to extend lifespan
5000+ Deep Cycles: 10x longer lifespan than lead-acid batteries; reduces replacement costs over time
Direct Lead-Acid Replacement: Standard 522240218mm dimensions; no modification required for existing systems
IP55 Dust & Water Resistant: Suitable for both indoor and outdoor use in harsh environments
UN38.3/MSDS Certified: Complies with international safety standards for air and sea transportation
