Product Details

Comprehensive Water Resistance

The PKCELL 46.8V 50Ah Surfboard Li-ion Battery is engineered with multi-layer waterproofing, far beyond simple sealing. A fully laser-welded metal shell eliminates weak points at seams, while U-shaped joints with rubber gaskets extend the water path and block potential leaks. Waterproof connectors and coils ensure secure charging, discharging, and signal transmission, while a waterproof breather valve allows air exchange without letting water in—providing reliable protection even under extreme marine conditions.
Lightweight & Slim Design

This battery is purpose-built for compact marine compartments, achieving a balance between strength and lightweight efficiency. The thin but durable sheet-metal casing replaces bulky plastics, and targeted sealing methods eliminate the need for heavy potting, reducing weight by 20–30% compared to fully potted marine batteries. With a space-saving internal layout, cells are firmly supported and the BMS is integrated directly, keeping the overall profile slim and efficient.
Safety Under Fault Conditions

Designed for the demanding environment of marine applications, this battery prioritizes safety in closed compartments. A waterproof breather valve releases internal pressure automatically during overheating or fault scenarios, preventing explosions while maintaining water resistance. At the same time, the built-in BMS continuously monitors voltage, temperature, and current, cutting off charging or discharging if abnormalities occur, ensuring a safe and stable energy supply.
Fast Charging & High-Rate Discharge

Built to keep up with the fast pace of marine operations, this battery supports rapid charging and high-power output. It can be recharged to full capacity in just about 1 hour, minimizing downtime for commercial or rental use. With a discharge rate of up to 3C, it delivers the strong bursts of power needed for propulsion systems, pumps, and other demanding marine equipment, ensuring consistent and powerful performance on the water.
