Xantrex 886-0050-36-B 36V 50Ah Lithium LiFePO4 Battery Group 31

The Xantrex 886-0050-36-B is a high-performance 36V 50Ah Lithium Iron Phosphate (LiFePO4) battery designed as a direct replacement for traditional lead acid Group 31 batteries in marine and mobile applications. Built with UL1642-certified cells and multiple redundant safety features, this battery delivers exceptional reliability for trolling motors, RVs, work trucks, and specialty vehicles.

Extended Cycle Life and Power Density:

Unlike conventional lead acid or AGM batteries that typically last 400-500 cycles, this LiFePO4 battery provides up to 4,000 charge cycles, offering dramatically longer service life and superior power density in the same Group 31 footprint. The advanced chemistry withstands harsh marine and mobile environments while delivering consistent performance throughout its lifespan.

Key Features:

• Intelligent sleep mode reduces self-discharge from 12.5% to 3% state of charge per month after 10 days of inactivity, extending battery life during storage
• High temperature rating allows charging up to 55°C (131°F) without battery damage
• Bluetooth connectivity enables real-time monitoring of battery status, state of charge, and fault codes via the Xantrex mobile app
• Integrated Battery Management System (BMS) provides self-protection against overcharge, over-discharge, and temperature extremes
• Remote on/off capability and fault notification for convenient system integration
• Optional heating blanket available for installations outside heated cabin spaces
• UN/DOT 38.3 certified for lithium-ion battery safety standards

Applications:

Ideal for recreational vehicles, heavy duty trucks, work trucks, marine vessels, trolling motors, and specialty vehicle applications requiring reliable deep-cycle power in extreme conditions.
