Application Scenarios
Our high-power marine lithium batteries are primarily designed for bait boats and are widely applicable to small fishing boats, yachts, sailboats, speedboats, marine emergency power supplies, and other marine equipment. These batteries provide stable and reliable power support for offshore fishing, lake cruising, and marine work applications.
Frequently Asked Questions
Can this battery be used for all types of bait boats?
Yes, compatible with most bait boats on the market. We offer multiple voltage (36V, 48V, 72V, 144V) and capacity (100Ah, 200Ah, 600Ah) options, plus customized solutions for specific power requirements.
What is the service life of this marine lithium battery?
Under normal use (80% DOD), cycle life reaches 8000 cycles with service life of 8-10 years, significantly longer than traditional lead-acid batteries (1-2 years). Built-in BMS extends battery life.
Is the battery waterproof? Can it be used in saltwater environments?
Yes, featuring IP65/IP67 waterproof and dustproof enclosures fully resistant to saltwater corrosion, humidity, and splashing. Specifically designed for marine environments in both saltwater and freshwater applications.
What is the function of the built-in BMS?
The Battery Management System acts as the battery's "brain," monitoring voltage, current, temperature, and SOC in real-time. It provides automatic circuit protection against overcharge, over-discharge, over-current, and short-circuit conditions while balancing cell voltages to ensure safe operation.
How long does it take to fully charge the battery?
Charging time depends on battery capacity and charger power. Typically 2-4 hours for 100Ah/200Ah batteries and 6-8 hours for 600Ah batteries. We recommend using dedicated lithium battery chargers for optimal performance.
Can multiple batteries be connected in series or parallel?
Yes, our batteries support series and parallel connections. Connect multiple batteries in series to increase voltage or in parallel to increase capacity for higher power requirements in large marine vessels. We recommend using identical models and capacities for connection.
