With three times higher energy density and 70% less weight than lead-acid batteries, E-Series batteries are perfect for smaller vessels with minimal interior storage space. This IP67 waterproof rated, 48V battery is designed for use with all 48V ePropulsion electric outboard motors.
Engineered for ease of use, its intelligent battery management system (BMS) is utilized to ensure the utmost safety for users. It features a colour HD display that shows state of charge, voltage, current and alarm information for maximum safety.
The E100 is designed for high reliability with an all-metal housing that is impact resistant and drop proof. Connectors can be attached with only one hand—no additional tools are required for simple installation.
Its compact, low-profile design allows for flexible installation, making it an ideal power source for a wide range of boat types3.
The chemistry of E-Series batteries is LiFePO4, which is 30% lighter but provides about 50% more usable capacity than AGM lead-acid batteries. In addition, LiFePO4 batteries have a long life of up to 3000 charge cycles, while the AGM batteries can only reach 300 to 500 cycles.
E-series batteries connect to a Navy motor directly, and to a Spirit motor with an External Battery Cable. E-series batteries require the E-Series Battery Charger to charge. Note that this battery does not include the charger, which must be purchased separately.
While 3rd-party batteries can be used with most ePropulsion electric outboard motors, only genuine ePropulsion batteries support hydrogeneration which recharges the battery during sailing. In addition, using using 3rd-party batteries does not allow for the use of a communications cable which brings data accuracy to the gauge and ensures useful operating strategy for safety and performance.
It’s possible to connect up to 16 E-series batteries (of the same model and same age) in parallel for increased total energy capacity and range. Requires a Battery Bridging Cable Set, a Battery Communications Cable and two Communications Terminators.
Key Features
- Flexible Voltage Configuration: The E100 powers 48V motors (1-6kW) including Spirit, Navy, and Pod Drive models. Uniquely, it is designed to support an upgrade to a 96V system by connecting two batteries in series, making it compatible with ePropulsion X12, P12, and 1-10 motors.
- Smart Design & Durability: Featuring an all-metal housing, the E100 is impact-resistant, drop-proof, and weather-resistant with an IP67 waterproof rating.
- Compact Footprint: With a height of just 240mm, the battery allows for flexible placement under seats or in tight storage spaces.
- Intelligent Monitoring: A built-in display provides real-time monitoring of State of Charge (SOC), voltage, current, and alarm status. It also integrates with third-party gateways for enhanced connectivity.
- Safety & Reliability: Equipped with a built-in intelligent BMS (Battery Management System) for maximum safety.
