Marine Applications

Like electric and plug-in hybrid vehicles, Lithium-ion technology is positioned as the technology of choice for marine vehicle traction. Lithium batteries are now able to replace the use of diesel fuel, allowing ship operators to meet emission restrictions and cost reduction targets.

Marine traction requires meeting strict criteria in terms of the safety of on-board systems, but also the reliability and robustness of the equipment.

Once again, the safety and very long service life of Lithium Ferro Phosphate technology make it an ideal candidate for this type of application.

BSLBATT® marine lithium batteries are the industry’s predominant choice for dual purpose – starting and deep cycle lithium marine batteries. Our batteries require Zero Maintenance are Plug & Play and come with a Limited Lifetime Warranty. With a life of 3000 – 5000 cycles, BSLBBATT marine lithium batteries can last 15 times longer than Lead Acid, Gel or AGM Batteries and are designed for use in all Marine Applications from Commercial Vessels, Yachts and Cruise Ships to Fishing Boats, Electric Propulsion, and Trolling Motor marine applications.

BSLBATT’s work with all 12V, 24V, and 36V trolling Motors and offer the greatest flexibility as a dual purpose battery for deep cycle and starting. Our marine lithium batteries hold above 13 volts for your trolling motor giving it the power it needs to keep running at its highest thrust throughout the entire day. In contrast lead batteries, their initial voltage starts at 12.8V and quickly goes down to 11V in strong current or winds. This causes your motor to run slower when you need power the most. Smart Battery uses LiFePO4 Lithium Iron Phosphate chemistry, a strong electrolyte capable of storing an extraordinary amount of power for up to 10 years. That provides nearly 100% usable capacity powering your trolling motor for the next 3000 fishing trips.

BSLBATT marine lithium batteries can be combined in series to increase voltage or in parallel to increase capacity. The built-in battery protection system independently maintains the cells and keeps the battery operating at its maximum capacity for thousands.

Power Your Aquatic Adventures

Cruisers, racers and anglers want to spend as much time on the water as possible. Long-lasting BSLBATT lithium iron phosphate (LiFePO4) batteries fit all types of watercraft and deliver the dependable power for everything you need, from punching your holeshot in competition to running your A/C at the dock.

Lithium Benefits for Marine

BSLBATT marine lithium batteries are built to last and designed to perform. Lightweight, durable and maintenance-free, our batteries charge quickly, store safely, and withstand the harshest temperatures and conditions.

Why moving on lithium ion service batteries (LiFePO4)?

For equal performance, a lithium ion battery for marine application BSLBATT® is more efficient, twice lighter and smaller. By comparison to lead-acid batteries, it represents a considerable space saving especially on board. To sum up, the energy density of a BSLBATT® battery lithium (service battery) is 4 times higher than the equivalent lead battery. In addition, a lithium Iron phosphate battery lasts around 10 years according to the use.

Besides, lithium ion service batteries have nor memory effect, nor maintenance, nor the possibility of a leak, neither gas emission.

The battery is the heart of the boat

Modern boats are more and more equipped with electronic devices that require constant power. A power cut onboard can be a critical event during navigation.

First of all, if you replace a lead-acid battery by a service lithium ion battery for marine applications, you need 50% less capacity in Ah to gey the same autonomy. Or you can take the same capacity and you will get twice more capacity.

By replacing your lead-acid battery by a lithium battery is quite simple :

Select voltage (12V, 24V, up to 48V) by assembling batteries in serie

Select battery capacity: We advise to replace a Lead acid battery by half capacity

Lithium battery: a 12V 110Ah AGM battery can be replaced by a B-LFP12V 55Ah

Set up branches in parallel if you need higher capacity and autonomy

Key points regarding lithium Ion batteries for boats, yachts and other marine applications:

Smaller and lighter batteries: This technology offers a strong specific energy (power to weight ratio) of about 10 years and 5000 cycles

High safety: LiFePO4 batteries are not subject to thermal runaway unlike other lithium chemistries
Each BSLBATT embeds a high end Battery Management System (BMS) to protect battery during operation.
