Lithium Iron Phosphate Battery (LiFePO4)
High-performance and durable lithium battery for electric boating
Why Choose The E-Series LiFePO4 Battery
Maximum Safety
The intelligent battery management system (BMS) is applied to provide maximum safety for the users.
High Energy Density
3 times higher energy density and 70% less weight than lead-acid batteries.*
Long Life Cycle
3,000 cycles at 80% DOD, the E-Series lifepo4 batteries power your motors much longer than lead-acid batteries.*
Easy to Install
The connectors of E160/E163 can be installed with only ONE hand. No additional tool is required.
Competitive pricing
Unit price of E40/E80/E175 is as low as $0.5 per watt-hour.
*Under equal capacity.
Fully Compatible with ePropulsion Motors
Data synced with ePropulsion motors to apply smart operation strategy.
The Features of the New E60 and E163 LiFePO4 Batteries
High Performance
E60 (single battery) can support Navy 3.0 Evo (3kW) full power output.
Flexible Installation
The height of E60 battery is only 300 mm, allowing flexible installation under the boat seat or other available spaces.
Lightweight
Features a new innovative double-layer plastic housing design weighing only 33 kg and can be easily lifted by two persons.
High Performance
E163 (single battery) can support Navy 6.0 Evo (6kW) full power output.
High Reliability
All-metal housing is more reliable, weather resistant, impact resistant and drop proof.
It’s Time to Replace your Lead-Acid Battery with our LiFePO4 Battery
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 longer life of up to 3000 cycles, while the AGM can only reach 300 to 500 cycles.

FAQ
ePropulsion batteries are designed for maximum efficiency, performance and safety. Using 3rd-party batteries does not allow for the use of our communication cable which brings data accuracy to the gauge and ensures useful operating strategy for safety and performance.
No. Third-party chargers are not allowed for warranty reasons. Consult with your dealer or ePropulsion on Facebook before you use a 3rd-party charger.
No. For parallel connection, E40, E60, E80, E163 and E175 can only be connected to the same model of the same age because they have different Battery Management Systems and different cell configurations.
It improves the signal quality. Without the communication terminator, E-Series batteries won't work in a parallel connection. Make sure you purchase this tool before a parallel connection.
Always power the master battery on/off first, not the secondary battery. If the secondary battery is powered on/off before the master battery damage or reduced usable capacity may occur.
No. The chargers for E40, E80 and E175 are universal. The E60 and E163 chargers are new E-Series chargers.
When the battery is not in use, make sure that the battery's connectors are covered well with waterproof caps. Protect against moisture, dust, water, shock and heat. Every 3 months of storage, the battery should be recharged to 60%.
No. The E-Series batteries can only connect in parallel.
