About this item

• 🍃【High-Energy Density Power】This 12V 314Ah LiFePO₄ battery delivers 4019Wh of usable energy in a lightweight 61.72 lbs design. Its compact 20.63×9.65×8.66 in metal-reinforced enclosure fits RVs, off-grid cabins, marine systems, UPS backup, and home emergency storage while maintaining a high 142Wh/L energy density.
• 🍃【EV-Grade Cells & Long Lifespan】Built with EV-grade A LiFePO₄ cells, the battery supports 6,000 cycles at 80% DOD and more than 10 years of lifespan. It provides stable voltage for solar storage, RV appliances, marine electronics, fishing gear, and off-grid systems, delivering long-term and reliable performance.
• 🍃【300A Smart BMS Protection】The integrated 300A Smart BMS supports up to 3840W continuous output and 350A peak discharge. It includes essential protections such as overload, over-discharge, short-circuit, over-current, temperature control, and cell balancing to ensure stable operation for high-power applications.
• 🍃【Durable Metal Frame & Low-Temp Cutoff】A full aluminum internal frame improves shock resistance, structural stability, and heat dissipation—providing up to 30% faster cooling under heavy loads. The IP65-rated shell defends against dust, rain, and marine environments, while the low-temperature cutoff pauses operation at –4°F to prevent cold-weather damage.
• 🍃【Bluetooth Monitoring & System Expandability】Built-in Bluetooth allows real-time monitoring of SOC, voltage, current, and temperature via the WattCycle mobile app. Supports 1C charging and compatibility with LiFePO₄ chargers, solar input, and generators. Expandable up to 4S4P to build large-scale systems up to 64.3kWh. Certified UN38.3, CE, FCC, and RoHS.
