Business Summary
Business Summary
eSURF BOARD S40
The body is made from durable, low-maintenance PE (polyethylene) material. PE is commonly used for canoes and kayaks, offering high impact strength while remaining highly flexible, and it can be repaired even when cracked or torn. Its low density provides excellent buoyancy, and its high chemical resistance makes it well-suited for use in seawater. PE also has insulating properties and low water absorption, making it ideal for this type of body construction.
The high-quality foot strap is designed for optimal comfort. This premium OEM foot strap is produced by an overseas brand with a long-standing reputation and trusted by thousands of users. All products undergo rigorous testing in various environments to ensure comfort and safety. The strap can be used in both regular and goofy configurations by adjusting the mounting position.

All components are modular and cable-free, making installation and removal from the board simple. The water jet propulsion system consists of a powerful BLDC motor, a motor driver, and a high-output water jet pump. Each component can be easily assembled and disassembled, allowing for straightforward maintenance and replacement.

Charger

The charger monitors the battery and connector status to ensure safe and stable charging. It will automatically shut down and emit an alarm if water is detected in the connector or if there is an issue with the battery, and it will display an error code to help resolve the problem.

Safe, Replaceable Battery Pack

The 2.8 kWh (56 Ah) battery is filled with materials that delay thermal runaway, enhancing safety and providing resistance to vibration and water ingress.

It fully charges in just 2.5 hours, with LED indicators showing the battery level. Equipped with a BMS, the battery maintains consistent performance by balancing the cells. It also features the ability to naturally adjust internal pressure.

Speed Controller

The controller displays the battery level through four LEDs, and if the battery level drops below 20% during use, it will issue a vibration warning and activate Emergency Mode, indicating that you should exit the water safely.

The internal PCB is coated for waterproof protection (IPX7 rating), and all components are easily replaceable.

Safe Lifeline Board Leash

The leash connects the board to the user, ensuring the board stays close if the user falls during operation, allowing immediate access back to the board.
