ePropulsion introduces E100 marine battery
The E100 has a capacity of 5,120 watt-hours
ePropulsion Americas has introduced the E100 battery, a new addition to its E-Series range of marine energy storage products. The E100 joins the existing E60 and E163 models, used with the company’s electric propulsion systems.
ePropulsion states that the E100 is based on lithium iron phosphate chemistry and has a capacity of 5,120 watt-hours. The 48V battery measures 9.5 inches, or 240mm, in height. Its form factor is intended to allow installation beneath seating or within confined onboard compartments. The unit includes removable decorative trim and a dedicated mounting bracket to support different installation arrangements.
The battery is compatible with ePropulsion electric motors, including the Spirit, Navy and Pod Drive, ranging from 1 to 6kW systems.
Up to 16 E100 batteries can be connected in parallel to increase total capacity. Two units can be connected in series to create a 96V configuration, which enables charging in under two hours. In a twin configuration, the batteries can support the ePropulsion X12, I10 and PodDrive 12 motors.
“We’re very proud to launch the E100 as the newest addition to ePropulsion’s E-Series batteries,” says Danny Tao, co-founder and CEO of ePropulsion. “This new battery is ready to consistently deliver reliability and high-performance to ePropulsion electric motors. We’re certain that users will appreciate its compact design for concealed installation, as well as its expandability to bring boaters sustainable power, no matter their vessel’s requirements.”
The E100 features an all-metal housing designed for marine environments and is described as weather-resistant, impact-resistant and drop-proof. It incorporates an integrated battery management system and provides real-time ‘state of charge’ monitoring.
The battery supports integration with third-party gateways to enable communication with onboard systems for energy management and monitoring. The company states a service life of up to 3,000 cycles while maintaining 80 per cent state of health.
The news comes after ePropulsion tech was showcased at multiple launches at boot Düsseldorf 2026, including the 16.1-metre Wia 520 HardTop, which is among the largest fully electric yachts currently available.
