Electric outboard batteries – safe, powerful & waterproof


  • E-Series Battery E40 Lithium Battery: 48V, 2048Wh

- For Extra Range, Powers Spirit 1.0 Plus / 2x Powers Navy 3.0 in series

  • E-Series Battery E80 Lithium Battery: 48V, 4096Wh

- 1 x Powers Navy 3.0 *

  • E-Series Battery E175 Lithium Battery: 48V, 8960Wh

- 1x Powers Navy 6.0 *

*An E175 battery will run a Navy 3 for 3hrs flat out, or a Navy 6 for 1.5hrs flat out. In most if not all applications, whilst the extra power is reassuring to have in case you really need it, you’ll find that half to two thirds power is almost as fast – whilst extending range and run time significantly. The E-Series batteries have in-built BMS systems that allow them to be linked together in parallel to make larger battery banks.

    The E-Series batteries are ePropulsion’s latest battery solution for 48V platform.  The chemistry is lithium iron phosphate, which is affordable, durable, and safe.  Under the same communication protocol and operating voltage, E-Series batteries work with all 48V ePropulsion outboards and pod drives.  These high-performance batteries will power any of the outboards or POD motors. The Spirit 1.0 Plus and 1.0 Evo electric outboard motors can be connected to the E Series batteries for longer range use, instead of using the integrated electric outboard battery. Multiple E Series batteries of the same size can be connected in parallel, to increase power output. Each E-Series battery has a different battery management system and cell configuration, hence only the same model can be connected in parallel.   Up to 16 x E40 E-Series Batteries can be run in parallel.  In addition these batteries can be used for brands of 48v systems including propulsion, home, or commercial solar systems etc. 

    All ePropulsion batteries are designed for maximum efficiency, performance, and safety. The batteries will discharge themselves and hibernate when not in use to protect themselves, so there is no need for any manual discharging.

    The affordable lithium E Series batteries are compact and energy dense and weigh 75% less than the equivalent lead acid battery. It is possible to use a 3rd party lead acid battery with the ePropulsion range, although the ePropulsion motor will not be able to access real time battery status. In addition, the E-Series batteries are designed to achieve the most efficient unit price on the market, as low as 40p per Watt-hour.

    • Affordable cost; 40p per Watt hour.
    • High energy density, space saving and lightweight; 75% less weight and space than the normal lead-acid battery. 
    • Long life span; 3000 cycles to 80% of original capacity.
    • Made for ePropulsion motors; data synced with ePropulsion motors to apply smart operation strategy.
    • Maintenance free; plug, play and charge.
    • Recyclable;  Recycling and redistribution is easy.
    • Modular design; 2 kWh to 143 kWh, up to 16 in parallel. 
    • Safe; Inherently safe chemistry.  Reliable BMS (Battery Management System) protection.  Robust shell.
    • IP67; Waterproof and shockproof.

    Note: Pallet delivery is required and so we can have these batteries ready for you to collect from us, or delivered to your industrial unit, as they are very heavy. Please allow for the £75 Delivery Charge.
