WattCycle 12V 628Ah LiFePO₄ Battery, Lithium Battery 12V 300A BMS, Built-in Bluetooth, Lithium RV Batteries 8038Wh Energy Storage, IP65 Waterproof, Perfect for Home Energy, RV, Marine, Solar, Off-Grid

• 🍃【High-Capacity Power】This 12V 628Ah LiFePO₄ battery delivers 8038Wh of usable energy, suitable for RVs, off-grid homes, marine setups, UPS, boat & fishing, and home storage. The compact metal case (18.9×9.53×14.25 in) and 153.99 lbs weight provide substantial capacity while maintaining a manageable installation footprint.
• 🍃【EV-Grade Cells & Long Lifespan】Built with EV-grade A+ prismatic LiFePO₄ cells, the battery supports 6,000 cycles at 80% depth of discharge and over 10 years of service life. It maintains stable voltage output for solar storage, RV appliances, marine electronics, and trolling motors, providing durable long-term performance.
• 🍃【300A Smart BMS Protection】The integrated Battery Management System supports 300A continuous discharge, 350A peak discharge, and 3840W max continuous output. It includes key protections such as over-voltage, over-discharge, over-current, short-circuit, and cell balancing for reliable performance with high-power applications.
• 🍃【Durable Metal Case & Low-Temperature Cutoff】A reinforced full-metal enclosure and internal aluminum frame enhance vibration resistance, structural stability, and heat dissipation—up to 30% faster under heavy load. The IP65-rated design provides dust and water resistance, while low-temperature cutoff pauses discharge below –4°F to prevent cold damage.
• 🍃 【Bluetooth Monitoring & System Expandability】Built-in Bluetooth 5.0 enables real-time monitoring of voltage, SOC, current, and temperature via the WattCycle app. Supports 1C charging, LiFePO₄ chargers, solar input, and generators. Can be connected in series or parallel (up to 4S4P) to build large-scale systems up to 128.6kWh. Certified UN38.3, CE, FCC, RoHS.
