High Capacity Marine Battery

Unmanned boats operate in extremely demanding environments. Moisture is everywhere, and ordinary batteries can corrode and fail quickly. This high capacity marine battery is rated IP67 waterproof and can withstand full water submersion.

Voltage options include 24V, 36V, 48V, and 60V. Capacity ranges from 30Ah to 150Ah. Continuous discharge is rated at 1C, while peak discharge reaches 2.5C. The cycle life exceeds 3,500 cycles. The operating temperature range is -20℃ to 60℃.

We established our first battery facility in 2014, giving us 12 years of hands-on manufacturing experience. Our Zhuhai plant covers 14,000 square meters. Two hundred thirty employees work on our production lines. Our engineering team previously supplied phone batteries to Siemens and Panasonic. Working with those companies taught us how to design products for harsh operating conditions.

This high capacity marine battery supports RS485 and CAN communication protocols, allowing the vessel to transmit operating data back to shore-based control systems.

Customization is available for battery size, cable outlet configuration, runtime requirements, and connectors. Simply send us your drawings or specifications. We support both OEM and ODM orders. The minimum order quantity is 100 sets.

Every battery pack undergoes full aging tests before shipment. Your order includes a 36-month warranty. Our support team responds quickly to customer inquiries.
