ePropulsion, company specialised in marine electric propulsion systems and services, announced today the E-Series Lithium Iron Phosphate (LFP) high-performance batteries for the pinnacle of performance in electric boating.
Edges of the E-Series
This affordable marine batteries are designed precisely to complement ePropulsion’s lines of Spirit and Navy electric outboard engines. The E-Series offers boaters unparalleled functionality, while reducing weight and space requirements compared to traditional AGM lead-acid batteries.
A key innovation of the ePropulsion product line is that all outboards are built on a 48V platform, allowing for a greater degree of flexibility. While third-party 48V batteries will work with these powerful engines, the E-Series batteries are designed for optimal performance for the entire range of engines, from 3 HP to 9.9 HP.
The E-Series provides long life cycles, consistent performance and smart operation for the easiest ownership experience. Connected with ePropulsion outboards and pod drives via a communication cable, ePropulsion motors are able to read all the data from the Battery Management Systems (BMS) and apply the best operation strategy.
Less consumptions and longer life
The E-Series LFP batteries are primarily designed to lower the overall cost of electric boating. The chemistry of E-Series batteries is 60% lighter but provides about 50% more usable capacity than AGM lead-acid batteries. As an example, a single 192-pound E175 E-Series battery will provide the same full-throttle run time to an ePropulsion Navy 6.0 6kW 9.9HP electric outboard as a 750-pound AGM battery pack.
In addition, E-Series LFP batteries have a longer life of up to 3,000 cycles, while AGM batteries only reach 300 to 500 cycles. This results in significant replacement cost saving for the E-Series versus lead-acid solutions. If used continuously every day for 8 years, the E-Series will retain more than 80% capacity available. Comparatively, the lead-acid battery has a short life span and for the same usage, will likely need to be replaced every two to three years.
Affordable and efficient
“We are excited to provide high-performance E-Series batteries to North American boaters and ePropulsion customers,” said Chris Ponnwitz, ePropulsion spokesperson and marketing specialist, Mack Boring & Parts Company.
“Offering an affordable option for powering your electric outboard, the E-Series brings the vast benefits of quiet performance, environmentally responsible propulsion and reliable operation to a wide-range of boaters.”
Technical features
Available in three models, the E-Series E40, E80, and E175 have a rated voltage of 48V and a lifespan of 3,000 charging cycles. E-Series batteries are tough and corrosion-resistant. Each model can be configured with up to 16 batteries connected in parallel.
The E40 has a capacity of 2048 Wh, can be charged in 2.5 hours with a 20A charger; weighs 61.7 pounds; and has a width, depth and height of 16.5-inches by 15.4-inches by 8.2-inches, respectively.
The 4096 Wh E80 can be charged in 2.5 hours with a 40A charger; weighs 105.8 pounds; and has a width, depth and height of 21.9-inches by 17.3-inches by 8.4-inches, respectively.
The 8960 Wh E175 has a 5-hour charge time with a 40A charger; weighs 191.8 pounds; and has a width, depth and height of 19.7-inches by 22.2-inches by 10.9 inches, respectively.
