Features

• High-Capacity 8.0kWh Energy SolutionThis 12V 628Ah LiFePO battery delivers a massive 8038Wh of usable energy, designed for RV power systems, off-grid cabins, marine installations, UPS backup, fishing equipment, and residential energy storage. The reinforced metal housing (18.99.5314.25 in) balances compact installation with ultra-high capacity at 153.99 lbs.
• Premium EV-Grade Cells for Long-Term UseEngineered with A+ grade prismatic LiFePO cells, offering up to 6,000 cycles at 80% depth of discharge and a service life exceeding 10 years. Maintains stable voltage output for solar storage, RV appliances, marine electronics, and high-load DC systems.
• 300A Smart BMS for High-Load ProtectionEquipped with an advanced 300A Smart BMS supporting 300A continuous discharge, 350A peak current, and up to 3840W continuous output. Comprehensive protections include over-voltage, over-current, over-discharge, short-circuit, and automatic cell balancing for system stability.
• Metal-Enclosed Durability & Cold ProtectionThe full-metal enclosure with internal aluminum reinforcement enhances vibration resistance and structural integrity while improving thermal efficiency by up to 30% under sustained loads. IP65-rated against dust and water exposure, with low-temperature cutoff activating below 4F to prevent cold-weather damage.
• Bluetooth Monitoring & Scalable DesignIntegrated Bluetooth 5.0 enables real-time monitoring of SOC, voltage, current, and temperature through the WattCycle app. Supports 1C charging, LiFePO chargers, solar controllers, and generators. Expandable up to 4S4P for large energy systems reaching 128.6kWh. Certified UN38.3, CE, FCC, and RoHS.
