Wattcycle BIG BEAST Of A Battery 628AH 8038WH Massive Power And Run Time

WattCycle 12V 628Ah Ultra Deep Cycle Lithium Battery

Experience industry-leading energy density with the WattCycle 12V 628Ah Ultra Lithium Battery, engineered to deliver exceptional performance and reliability. Incorporating EV-grade A+ cells, a robust 300 A BMS with configurable over-current protection, and expandable 4 P × 4 S scalability for up to 128.61 kWh, this 12V 628Ah Ultra Lithium Battery sets a new benchmark in power storage.

Advanced Wireless Control

Equipped with Bluetooth 5.0, the WattCycle APP transforms your smartphone into a command center for the 12V 628Ah lithium battery. With a few taps, you can remotely initiate or suspend discharge, verify system health, and monitor critical metrics—voltage, current draw, and cell temperature—in real time. Parameters such as the 300 A continuous discharge limit and peak over-current cutoff can be fine-tuned on the fly, ensuring your WattCycle 12V 628Ah LiFePO4 battery operates precisely to your requirements.

Extreme-Environment Protection

Built to withstand the harshest conditions, the WattCycle 12V 628Ah Ultra lithium battery employs intelligent thermal safeguards that automatically pause charging below 32 °F (0 °C) and only resume once ambient temperatures exceed 41 °F (5 °C). In even more severe cold, discharge is halted below –4 °F (–20 °C) to prevent cell damage. Once the environment returns to safe thresholds, the system seamlessly restores full functionality—ensuring your 12V 628Ah Ultra Lithium Battery delivers uninterrupted power whether you’re braving sub-zero winters or scorching summer heat.

Decade-Long Backup Endurance

EV grade A+ LiFePO4 calls have a longer lifespan, better-refined manufacturing, and contain more energy per cell. Engineered for unwavering reliability, the WattCycle 12V 628Ah lithium battery delivers over a decade of continuous backup power, ensuring mission-critical systems stay online through countless cycles. This exceptional longevity means your investment in the 12V 628Ah Ultra Lithium Battery pays dividends year after year, with minimal capacity fade and maximum uptime for residential, commercial, and industrial applications.

Superior Performance vs. Lead‑Acid

Unlike conventional lead‑acid designs, the WattCycle 12V 628Ah Ultra Lithium Battery is encased in UL94 V‑0 flame‑resistant ABS+PC housing and carries an IP65 ingress rating, delivering industry‑leading fire safety and protection against dust and water. This rugged enclosure means you can install it in harsh industrial settings, dusty warehouses, or aboard marine vessels with confidence—environments where traditional batteries often fail or require frequent maintenance. Coupled with the inherent maintenance‑free LiFePO4 chemistry, which eliminates watering and minimizes self‑discharge, this robust design lowers your total cost of ownership and guarantees reliable power delivery when you need it most.

Modular High-Capacity Configuration

Each WattCycle 12V 628Ah Ultra LiFePO4 battery stacked individual battery delivers 8038.4Wh of energy. For projects demanding even greater power, 16 batteries in 4P4S can create a 51.2V 2512Ah system that unleashes a colossal 128.61 kWh of energy. With a truly gigantic energy capacity, this system easily supports any energy demands. Whether you’re expanding a commercial backup system or building a residential microgrid, the 12V 628Ah Ultra Lithium Battery adapts without compromising reliability or performance.
