ePropulsion Launches New E-Series Battery Line

Somerset, N.J. – ePropulsion, a global leader and market challenger in marine electric propulsion systems and services, announced today its new range of E-Series batteries for 2023. With a more ergonomic design, the E60 and E163 will supplement the existing E80 and E175 batteries in the range. The E-Series provides consistent performance and smart operation, delivering up to 3,000 charging cycles for a reliable user experience.

ePropulsion’s new E-Series Lithium Iron Phosphate batteries are high-performance and packed with features. With three times higher energy density and 70% less weight than lead-acid batteries, the E-Series is perfect for smaller vessels with minimal interior storage space. Connectors can be attached with only one hand – no additional tools are required for simple installation. IP67 waterproof rated, the E60 is designed for use with the ePropulsion Navy 3.0 Evo (6HP) and the E163 is designed for the Navy 6.0 Evo (9.9HP). Engineered for ease of use, their intelligent battery management system (BMS) features a display that shows state of charge, voltage, current and alarm information for maximum safety. The E60’s compact form factor and light, double-layer plastic housing can easily be transported and installed by one person, while the E163 is designed for high reliability with an all-metal housing that is impact resistant and drop proof.

“While capacity is an obvious focus of user-oriented innovation, making batteries easier to use is also vital to promoting adoption of electric propulsion,” said Danny Tao, CEO, ePropulsion. “ePropulsion electric outboard engines, combined with the new batteries are the perfect solution for boaters looking to embrace quiet, clean and environmentally conscious propulsion.”

A key innovation of the ePropulsion product line is that all outboards are built on a 48-volt architecture, allowing for a greater degree of flexibility. ePropulsion E-Series batteries are designed to provide optimal performance for the entire range of ePropulsion electric motors.

ePropulsion and the new E-Series range will be available at boot Holland from March 8-12, at Stand 3101. For more information on the ePropulsion or its revolutionary electric motors and accessories, please visit www.ePropulsion.com or mackboring.com/products/epropulsion-motors.

    ePropulsion has come a long way since I got hand’s on with their 3hp equivalent electric outboard back in 2020 — https://panbo.com/?s=epropulsion

    In fact, though not on Panbo, ePropulsion even has e-inboard motors now, from 10 to 100kW, and their obvious intent is to compete with Torqeedo at every level.
    Meanwhile, all their outboards and pod drives (9.9 “hp” max) are unified at 48v DC now and that’s what these sleek new LiFePO4 batteries are about. Manuals and other details aren’t available yet, but the E60 and E163 seem to integrate very nicely with all their 48v motors.

    What I wonder about is can you, say, build a smallish sailboat with an ePropulsion pod system and also use the 48v bank for appliances like a 48v windlass or bow thruster, or to step down to 12 and/24 v devices?

  2. Chris DeBoy says:

    Ben, we completely agree with your comment about other 48V appliances, such as Windlass and Bow Thrusters also able to utilize the 48V bank. VETUS offers a full range of thrusters and windlass at 48V for boats 20′ to 100′, as well as 48V propulsion products.

  3. I acquired this bleeding edge tech last year here in Ireland. I’ve had very mixed experience with it. Starting with a shock when I hit the throttle on my heavy wooden daily workboat, which takes me from the little island off the SW coast of Ireland (Heir Island) where our cottage is, and almost falling backwards off the boat due to the massive torque on my Navy 6.0! WOW! To the massive challenge of lifting a 90kg (150lbs?) battery into the boat, ugh! and then trying to figure out how to charge a battery where there is no marina! Sh*!t… presently I’m working on a small floating pontoon with solar and wind mounted atop. This is the big killer on this tech, how to successfully use it in more remote locations.

    I was told when I bought it that the battery was built to be in the elements, but I can tell you that it’s not. Seems obvious now, but it needs housed. That’s where these new batteries look promising. They are lighter, but still very heavy, 33kg and 76kg, and look significantly more water resistant. That’s still a two person job and not suitable for a non enclosed boat. I was clear on my needs and told it would be fine… but not the case. This is totally not the case for the Spirit models, where the battery comes off and goes into a handy backpack to take ashore easily and recharge, which we love. This is what sold us to buy the bigger, but it’s a massive step up in using heavier gear.

    I had the circuit board go on my Navy 6.0 after just six months. I can’t tell you the hassle in returning a heavy motor back to the UK (especially after Brexit) for repair because no one in the country of Ireland could do it(meaning they have no repair partners outside the UK)! So, be careful if you’re remote at ALL. Really, I’ve no doubt it would be an easy fix, pop the lid and replace the board, but not under warranty!

    On my large battery (biggest they sell) the motor cable plug has come loose and the LEDs showing battery capacity are now faulting… sending that back would be double the nightmare. Again, easy fix, but not under warranty. So, although we LOVE the silence of the Navy 6, and the power and even the distance it takes us, be wary of the bleeding edge, and the lack of support away from Southhampton, UK, or China, where the main office is! Oh, and likely wherever the base the US is.

      Thanks for the report, Randy, and sorry about the hassles you’re having with your ePropulsion Navy 6.0 system. I notice that one of their marketing photos shows two of the first gen E80 batteries panel up in the back of a SmokerCraft, even the power terminals fully exposed. Doesn’t look like a safe or long-lasting install to me!

      But ePropulsion has impressive service and distribution here in the States. It’s managed by Mack Boring, which also handles Yanmar, Scania, and several other major propulsion lines. I went to their Dealer Locator page, filtered for ePropulsion, and it looks like there are three servicing dealers within 80 miles of where I live in Maine:

      Again, sorry this doesn’t apply to you, Randy, but Heir Island does look fascinating.
