  • 🍃【8kWh-Class Single Battery Power Bank】This WattCycle 12V 628Ah LiFePO₄ battery delivers 8038Wh of usable energy in a single unit, reducing the need for multi-battery parallel wiring. Designed for RV power walls, off-grid homes, marine electrical systems, UPS backup, and large solar installations requiring long runtime and stable output.
  • 🍃【A+ EV Prismatic Cells for Consistent Output】Built with A+ grade prismatic LiFePO₄ cells, the battery maintains stable voltage under sustained loads and supports over 6,000 cycles at 80% DOD. Ideal for continuous solar charging, RV appliances, DC equipment, and marine electronics where reliability matters.
  • 🍃【300A Smart BMS for Heavy Electrical Loads】An integrated 300A Smart BMS supports 300A continuous discharge and up to 350A peak current, delivering consistent power to high-demand inverters and DC systems. Full protection includes over-charge, over-discharge, over-current, short-circuit, and intelligent cell balancing.
  • 🍃【Industrial Metal Housing with Thermal Optimization】The reinforced metal enclosure with an internal aluminum frame improves shock resistance and structural strength while enhancing heat dissipation by up to 30% under high load. Rated IP65 for dust and water resistance, with automatic low-temperature cutoff below –4°F to protect battery health.
  • 🍃【Bluetooth Control & System-Level Expansion】Bluetooth 5.0 allows real-time monitoring of SOC, voltage, current, and temperature via the WattCycle App. Supports 1C charging through solar controllers, generators, or LiFePO₄ chargers. Expandable up to 4S4P configurations for total system capacity up to 128.6kWh. Certified UN38.3, CE, FCC, and RoHS.
