Resilience for Extreme Energy Needs: The WattCycle 12V 628Ah Ultra Bluetooth LiFePO4 Battery redefines energy storage with massive capacity and intelligent design. Built with advanced LiFePO4 technology, it ensures unmatched reliability, high cycle endurance, and scalable energy for motorhomes, yachts, solar storage, and commercial backup systems. Ultra-High Usable Energy of 8,038Wh: Compact yet powerful, this battery provides more than 8kWh of storage in a single unit (L480 × W362 × H242 mm, 69.85 kg). Equivalent to two 12V 314Ah batteries in parallel, it maximizes space and energy efficiency for motorhomes, off-grid homes, and marine applications. Premium EV-Grade A+ Cells: Manufactured with prismatic automotive-grade cells, this 12V 628Ah Ultra lithium leisure battery offers superior stability, safety, and durability. It achieves over 6,000 cycles at 80% DoD, delivering up to a decade of reliable use—far exceeding standard lithium batteries. Smart Bluetooth Monitoring & Flexible Expansion: Monitor real-time performance—voltage, SoC, current, temperature via the WattCycle app. Configure up to 4 in parallel (2,512Ah) or 4 in series (51.2V) for a total 128.61kWh capacity. After expansion, users can easily track each battery’s status and manage charging/discharging through Bluetooth. Powerful 300A Continuous Discharge: Equipped with a robust 300A BMS, the battery delivers 3,840W continuous output, supporting heavy-duty inverters, industrial-grade equipment, and high-demand off-grid systems. Triple Energy Density of Lead-Acid: At 115Wh/kg, this LiFePO4 deep cycle battery achieves three times the energy density of traditional lead-acid batteries. Lightweight yet powerful, it is ideal for campervans, marine vessels, and mobile energy storage solutions. Constructed with recyclable materials, it is maintenance-free and eco-friendly. Advanced 8-Fold Safety Protection: The integrated 300A BMS provides critical safeguards, including over-charge, over-discharge, over-current, short-circuit, and temperature protections. Charging cut-off: -5°C to 60°C; discharging cut-off: -25°C to 75°C, ensuring safe use in extreme environments. Wide Application & Optimized Lifetime Value: Designed for off-grid residences, solar storage systems, motorhomes, boats, farms, UPS backup, and emergency power, the WattCycle 12V 628Ah Ultra offers exceptional longevity, reducing overall cost of ownership and ensuring energy independence.
