Relion RB80 LiFePO4 12V 80Ah Lithium Battery Group 27

The Relion RB80 is a high-performance lithium iron phosphate (LiFePO4) battery that delivers exceptional power in a lightweight, compact package. Designed for marine, RV, and off-grid applications, this 12-volt, 80 amp-hour battery offers superior energy density and reliability compared to traditional lead-acid batteries.

Key Features:

• Group 27 form factor for easy drop-in replacement of lead-acid batteries
• Weighs approximately 26 pounds—over 60% lighter than comparable lead-acid batteries
• Delivers 80 amp-hours of consistent power with flat discharge curve
• 3,000+ cycle life at 80% depth of discharge for years of reliable service
• Built-in Battery Management System (BMS) protects against overcharge, over-discharge, and short circuit
• Operates efficiently in temperatures from -4°F to 140°F (-20°C to 60°C)
• Fast recharge capability accepts high charge currents
• Maintenance-free design with no watering, equalizing, or off-gassing
• Can be installed in any orientation without performance loss
• Safe, stable LiFePO4 chemistry with no risk of thermal runaway

The RB80 is ideal for trolling motors, house banks, solar energy storage, and other deep-cycle applications where weight savings and long service life are critical. Its advanced BMS ensures optimal performance and safety, while the maintenance-free design eliminates the hassles associated with flooded lead-acid batteries.
