Introducing E-Series LiFePO4 Batteries

Updated: Oct 14

ePropulsion is pleased to introduce its new E-Series LiFePO4 batteries. The new battery family, which builds on the 48V platform, features E40 (2048Wh), E80 (4096Wh), and E175 (8960Wh). E-Series batteries are designed to provide an affordable, high performing electric outboard system. They are designed for ePropulsion outboards and pod drives, as well as many 48V marine motors of other brands.


Best Price

The unit price of the E-Series batteries drops to $0.45 per Wh. Compared to other LFP batteries, this is a 50% unit price drop. In the U.S., the cost for the E40 battery is $999 for 2048Wh, E80 is $1,999 for 4096Wh, and the E175 is only $3,999 for 8960Wh. We have incredible Navy 3.0 / 6.0 outboards, but sometimes people give up electric boating due to the battery cost. Affordability is the main reason we designed the E-Series battery. Thanks to the unmatched battery supply chain resources we have in China, we were able to design and present this exceptional battery to the market for a great price.


Long Lifespan

The new chemistry LiFePO4 makes a notable difference.

Our E-Series batteries have an impressive 3000 cycles of battery life at 80% DOD. It is six times the lead-acid battery’s life span. Commercial clients could feasibly use E-Series batteries every day continuously for over 8 years. This brings the average operation cost per year to a lower level and saves labor cost of replacing used lead-acid batteries.


Save space and Less Weight

E-Series batteries are compact with high energy density. For example, the E80 weighs 106 lbs with a capacity of 4096Wh / 48V. To have the same rated capacity, the normal AGM lead-acid battery pack will be about 220 lbs, twice the weight of the E80. Considering the less usable capacity of lead-acid batteries, the actual weight will be even more for AGM battery buyers. E-Series batteries are ideal for electric boating when you want to use maximize capacity in a limited space.


Made For ePropulsion

Our E-Series batteries were specifically designed for, and work best with ePropulsion motors. Connected with ePropulsion outboards and pod drives via a communication cable, ePropulsion motors are able to read all the data from the BMS sensors and apply the best operation strategy. When ePropulsion outboards are powered by third-party batteries there is a possibility they will display an inaccurate remaining runtime, up to a 20% discrepancy.

Design Details

The battery shell is made of high-quality stainless steel with IP67 ingress protection. E-Series batteries are tough and corrosion-resistant. So they adapt to the marine environment better than normal multi-purpose batteries. On the connector side, you will find two CAN communication ports for parallel connection, one RS-485 port for motor communication, 6 LED indicator lights, and an error alarm.

Affordable, powerful and reliable, E-Series LiFePO4 batteries are the best for ePropulsion motors.
