12.8V 280AH Home Energy Storage System For RV / Yacht / Boat VP Emergency Power Supply Battery

• Intelligent BMS and Grade A Cells
• Longer Life and Strong Power Output
• IP20 Rated Enclosure Protection
• High charge and discharge currents
• Smaller Size But Larger Capacity For RVs Lithium Battery Solutions

FT12-280 Lithium batteries deliver reliable, high-performance energy for motorhomes, travel trailers, and off-grid camping. Unlike traditional lead-acid batteries, our lithium technology delivers 280AH usable capacity with 6,000+ cycles and ultra-fast recharge capability, with lighter weight, zero maintenance, and stable power output even in extreme temperatures (-20°C to 40°C). Ideal for powering high-demand RV systems—including air conditioners, refrigeration units, and lighting networks—their resilient performance supports extended boondocking, solar integration, and long-haul expeditions.

• The battery needs to be kept warm in winter and heat dissipated in summer.
• Keep away from acid and alkali solvents (such as garage paint, cleaning agents).
• Wiring needs to be protected by insulating sheath.
• Maintain the battery SOC at 50% charge when parked for a long time.
• Operate within humidity range 5-95% (IP20 limits).

Suitable for mobile power supply units for vehicular/outdoor applications with integrated BMS protection. Meet the ultimate lithium battery solution for campers, boats, and renewable energy systems.
