Product Features:
Stable voltage output:
The 48V Lifepo4 Marine Battery uses Class A cells, and the dynamic voltage difference is controlled within 50 millivolts (0.05V). Ensures stable voltage during the charge and discharge process, and improves the efficiency and safety of the ship system.
Extremely long service life:
The battery uses laser welding technology, which makes the connection more secure and has lower internal resistance.
Reduces cell heating, extends the battery life, and the performance remains stable after cycling.
Lightweight design:
Compared with lead-acid batteries, the LiFePO4 Battery is about 30% smaller in volume and 50% lighter in weight.
It is more convenient to install and transport, and use this battery to improve the performance and stability of the ship.
Waterproof and Durable:
Waterproof grade IP65
High-strength PVC shell or customizable stainless steel shell, waterproof glue is used inside to seal gaps and holes
Moisture-proof and corrosion-resistant, suitable for harsh marine environments
Application Areas:
Electric propulsion system
High-power trolling motor
Critical systems such as shipboard navigation, communication, emergency power supply, etc.
The battery is also suitable for yachts, speedboats, cargo ships, passenger ships, etc.
