Relion RB100HP 12V 100Ah LiFePO4 Lithium Battery Group 31

The Relion RB100HP is a high-performance lithium iron phosphate (LiFePO4) battery designed to deliver reliable 12-volt power for marine, RV, off-grid, and industrial applications. This Group 31 format battery offers 100Ah capacity with exceptional power density, weighing significantly less than comparable lead-acid batteries while providing superior performance and longevity.

Key Features:

• Advanced LiFePO4 chemistry provides 2000-5000+ cycle life at 80% depth of discharge
• Lightweight design at approximately 31 pounds—60% lighter than lead-acid equivalents
• Flat discharge curve maintains consistent voltage throughout the discharge cycle
• Fast charging capability with high charge acceptance rates
• Built-in Battery Management System (BMS) protects against overcharge, over-discharge, and short circuit conditions
• Maintenance-free operation with no watering, equalizing, or sulfation concerns
• Wide operating temperature range from -4°F to 140°F (-20°C to 60°C)
• Group 31 form factor for easy replacement of existing lead-acid batteries
• Safe and stable LiFePO4 chemistry with no risk of thermal runaway
• Can be connected in series for 24V or 48V systems or parallel for increased capacity

The RB100HP is ideal for applications requiring deep-cycle performance, including house banks, trolling motors, solar energy storage, and backup power systems. Its advanced lithium technology delivers more usable power, faster recharge times, and dramatically longer service life compared to traditional flooded or AGM batteries.
