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.

• Q: How long does it take to fully charge the 12V 200Ah 0.5C battery?
  A: With a 100A (0.5C) charger, it takes approximately 2 hours to fully charge the battery.
• Q: Can I connect multiple batteries in parallel or series?
  A: Yes, you can connect up to 4 batteries in series (48V) and up to 16 batteries in parallel for increased capacity.
• Q: How does this LiFePO4 battery compare to a lead-acid battery?
  A: LiFePO4 batteries have 10x longer lifespan, 50% lighter weight, faster charging, and higher energy density than lead-acid batteries. They also require no maintenance and are more environmentally friendly.
• Q: What is the lifespan of the battery?
  A: The battery has a lifespan of 5000+ deep cycles at 0.5C charge/discharge and 80% depth of discharge, which is equivalent to approximately 10-15 years of normal use.
• Q: Is the battery safe to use?
  A: Yes, LiFePO4 chemistry is inherently safe and non-flammable. The integrated BMS provides comprehensive protection against overcharge, overdischarge, overcurrent, and short circuit.
