Battery – Long-Lasting for Every Trip

Advanced BMS 3042 Wh Aluminium Unibody Housing
Safety comes first: includes six protection features Terrific capacity in a compact size Robust and extremely thermally conductive

The ePropulsion Navy battery is more than the outstanding capacity. It’s designed specifically for our Navy series and it is capable of discharging at maximum current for hours. It also looks good and performs even better.

Carefully Designed Battery Components

Each Navy battery contains a huge 31,218,650 cells in total. To best optimize performance and thermal dissipation a sophisticated battery array was designed to create a large capacity in a compact size.


  1. Communication Port
    The BMS controller reads the real-time battery status from this port and implements the best control strategy for performance. Each Navy battery has two for parallel connection
  2. Handle
    Two ergonomically designed handles are incorporated to enable safe carrying of the battery
  3. Power Switch
    Switch between sleep and working mode – Helping to preserve battery life
  4. Aluminium Unibody Sealed Housing
    Excelling at thermal dissipation and designed for long term saltwater environment protection includes an air vent located on the top of the housing to balance pressure


Robust Design Built to Last

Maintenance-Free 2,000 hrs in Testing Direct Drive
Save time at work and spend more time on the water The most rigorous testing of continuous operation ensures a robust design The amount of moving parts is reduced tremendously, including gear box

The ePropulsion Navy 3.0 is a maintenance-free electric outboard motor. You’ll never need to worry about repairing or maintaining it. The quality and craftsmanship is so dependable you can relax and enjoy your time on the water!

Perfect, even after 2,000 hours of testing – On 5th February 2017 ePropulsion ran a continuous operation test on the Navy 3.0 of 2,000 hrs (two and half months). It passed with flying colours, and could have run many thousands of hours more. On a traditional conventional petrol outboard engine maintenance has to be undertaken every 50-100 hours

FOC 60 dB Comfortable Tiller
Field-oriented control (FOC) smoothes the motor operating with less vibration Max operating noise equals the db level of a normal conversation No  uncomfortable vibrations when holding the tiller

A petrol outboard engine could never compete with an electric outboard motor, and unsurprisingly the Navy 3.0 has a better noise control level than another electric outboard brands. You can comfortably have a conversation and be easily heard.

Pleasant Travel – You won’t even notice the noise of the electric motor, so relax and immerse yourself on the experience of the water. There’ll be no more speaking loudly over a noisy petrol outboard!

Average Office 50 dB
