MG LFP 25.6V LiFePO4 Series Battery (230/280/304Ah)

The MG LFP 25.6V Series is a next-generation LiFePO4 battery built for serious house banks on boats, RVs, and off-grid systems. Each module carries an integrated slave BMS, passive cell balancing, and a 300A internal fuse, and talks to an MG Master controller over CAN-Bus so larger banks stay coordinated and protected. Three capacities let you size the bank to the boat or build, and the modules scale up to six in series and many in parallel for large 24V (or higher-voltage) systems.

Key Features

• Next-generation LiFePO4 chemistry for safety, stability, and long service life
• Integrated slave BMS with passive balancing in every module
• 300A internal fuse (replaceable with non-fused poles for high-power/high-voltage builds)
• CAN-Bus communication (RJ45 or M12) to an MG Master LV or HV controller
• Scalable: up to 6 modules in series and up to 96 in parallel
• M8 stud power connections (20 Nm), air/convection cooling, IP30 enclosure
• 3,500-4,000 cycle life at 80% DOD (end-of-life defined as 70% capacity)
