Xantrex 883-0125-12 LiFePO4 Lithium Battery 125Ah 12V Group 31 Deep Cycle

The Xantrex 883-0125-12 is a high-performance Lithium Iron Phosphate (LiFePO4) battery engineered for demanding mobile and marine applications. This Group 31 drop-in replacement delivers 125Ah capacity at 12.8V nominal voltage (1600Wh), providing superior power density in a compact footprint that fits standard battery compartments.

Advanced Safety and Protection:

Built with UL1973 certified cells and equipped with redundant safety features, this battery includes an integrated Battery Management System (BMS) that monitors state-of-charge, voltage, current, and temperature. The IP65-rated enclosure protects against water and dust ingress, while the heavy-duty metal construction withstands harsh environments. Individual cell management prevents damage from spreading between cells, and temperature control safeguards against charging at unsafe temperatures.

Exceptional Cycle Life:

Designed to deliver up to 6,000 deep discharge cycles—far exceeding the 400-500 cycles typical of traditional lead-acid or AGM batteries. This extended lifespan translates to years of reliable service with significantly lower total cost of ownership. The internal cell balancing system ensures optimal performance throughout the battery's lifetime.

Smart Monitoring and Connectivity:

• LED indicators on battery side display state of charge percentage and error fault codes at a glance
• Bluetooth connectivity allows real-time monitoring via the Xantrex mobile app (iOS and Android)
• Remote panel port enables external display installation for viewing battery status and on/off control
• Parallel stacking capability supports up to 4 batteries for expanded capacity systems
