- 🍃 【4019Wh High-Capacity Energy in a Single 12V Battery】 Delivering 4019Wh of usable power, the WattCycle 12V 314Ah LiFePO₄ battery consolidates high energy density into a compact form factor. With a reinforced metal enclosure measuring 20.63 × 9.65 × 8.66 in, it fits easily into RV compartments, solar cabinets, marine storage bays, and home backup systems while achieving an efficient 142Wh/L energy density.
- 🍃 【EV-Grade Lithium Cells for Long-Term Use】 Constructed with EV-grade A LiFePO₄ cells, this battery supports 6,000 cycles at 80% DOD and delivers over 10 years of dependable service. Designed for stable voltage output, it reliably powers solar inverters, RV appliances, marine electronics, and off-grid loads without the voltage sag common in lead-acid systems.
- 🍃 【300A Smart BMS for High-Power Loads】 The built-in 300A Smart BMS enables up to 3840W continuous output with 350A peak discharge, making it suitable for high-demand devices such as inverters, electric cooking equipment, and marine motors. Comprehensive protections—including over-current, over-discharge, short-circuit, thermal control, and cell balancing—ensure safe and consistent operation.
- 🍃 【Metal-Reinforced Structure with Cold Protection】 An internal full-aluminum support frame enhances structural integrity, impact resistance, and thermal efficiency, improving cooling performance under sustained loads. The IP65-rated housing protects against dust, moisture, and marine exposure, while low-temperature cutoff at –4°F safeguards the battery during winter conditions.
- 🍃 【Bluetooth Monitoring & Modular Expansion】 Integrated Bluetooth connectivity allows real-time monitoring of SOC, voltage, current, and temperature through the WattCycle App. The battery supports 1C charging and works seamlessly with LiFePO₄ chargers, solar controllers, and generators. Expandable up to 4S4P, it enables scalable energy systems reaching 64.3kWh.
