Product Description

48V 100Ah Great Marine Battery For Outboard Motors, Inflatable Boats, Small Sailboats Or Motorboats


Product Introduction


Bonnen EM-LFP48-100A marine batteries harness advanced lithium battery technology to deliver exceptional deep cycling capabilities and reliable performance. Engineered to withstand shock and vibration, they thrive in challenging marine environments. Whether opting for LiFePO4 lithium batteries, maintenance-free and adaptable to various mounting positions, or other variants, our marine batteries are designed to endure harsh marine conditions. With robust construction, resilient components, and outstanding vibration resistance, they ensure consistent power output on the water.

Suitable for a range of boat types including fishing boats, recreational vessels, sailboats, pontoons, and more, our marine batteries guarantee dependable performance whether navigating the open sea, cruising on a lake, or enjoying river activities.



Product Features


1. IP67 Rated, Dust and WATERPROOF: Ensuring complete protection against dust ingress and resistance to water penetration. With this level of certification, the product can withstand immersion in water up to 1 meter deep for up to 30 minutes, making it ideal for use in wet or dusty environments without compromising performance or durability.


2. Built-in Smart Battery Management System (BMS): The integrated BMS provides comprehensive cell protection features, including: overcharge, over discharge, over-voltage protection, active cell balancing, charge monitoring and control, temperature protection for cells and BMS, and short circuit protection.


3. Fast Charge Time: Charging time is a critical consideration for every battery. Lithium batteries outpace lead-acid counterparts in charging speed, plain and simple. Our lithium batteries can be fully charged in as little as an hour, although we recommend a charge rate that completes charging within 2-5 hours for optimal performance.


4. Rugged mechanical design: Our 48V lithium batteries are built to endure marine conditions, ensuring reliability in rough seas and harsh weather. With reinforced casing and robust internals, our batteries offer peace of mind for electric boat owners.


5. Eco-Friendly & Safe: Our 48V marine lithium batteries epitomize clean energy excellence. Free from gassing, fumes, or pollution, these non-hazardous batteries provide reliable power while protecting the environment.


6. Unmatched Voltage Consistency: Our 48V marine lithium batteries boast unmatched voltage stability. Engineered for consistent power output, they maintain steady voltage levels throughout the discharge cycle. Whether you're cruising calm waters or navigating rough seas, rely on Bonnen Battery for optimized electric propulsion system performance and smooth sailing.
