Waterproof Marine Battery Manufacturer | OEM WholesaleHigh Power Waterproof Lithium Batteries for Electric Surfboards & Underwater Diving Propulsion
$86.99
IP68-rated sealed construction with saltwater-corrosion-resistant housing keeps the pack safe during full submersion, high-speed water impact and long exposure to hot marine climates. Hot-swappable design lets riders and divers change batteries in the water without returning to shore — a decisive advantage for rental fleets and dive boats.
High-rate discharge cells deliver sustained power to 10 kW-class surfboard motors and high-torque underwater thrusters, with intelligent BMS protection against over-current, over-temperature and deep discharge. Real-world capacity you can rely on for 1–2 hours of riding or multiple dives.

Description
Our 24V LiFePO4 battery is a deep cycle lithium iron phosphate battery pack built to replace heavy lead-acid batteries in RVs, off-grid solar systems, marine applications and emergency backup power. The rugged black case with integrated carry handle and built-in display makes it easy to transport, install and monitor.
### Why Choose Our 24V LiFePO4 Battery
The 24V LiFePO4 battery uses Grade A LFP cells that deliver over 6,000 cycles at 80% depth of discharge — up to 5 times longer than lead-acid. You can discharge it deeply every day without shortening its life. It weighs roughly half of an equivalent lead-acid battery, and the built-in handle makes it practical for mobile use.
The LCD display shows real-time voltage, current, state of charge and temperature. The built-in BMS protects against overcharge, over-discharge, over-current, short circuit and overheating. Pre-connected heavy-gauge leads with quality connectors make wiring straightforward.
