  • Yes, but parallel connection is required. To power one Navy 3.0 Evo with a E40, you need two E40 batteries in parallel. To power one Navy 6.0 Evo with E80, you need two E80 batteries in parallel.
  • We recommend the E80 battery for the Navy 3.0 Evo, and E175 battery for the Navy 6.0 Evo. For more info, please check ePropulsion Tutorial: ePropulsion E-Series Battery | General Instructions
    • First, our original E-Series battery has the best unit price on the market, as low as $0.46 per WattHour.


    • Second, the E-Series battery weighs 70% less than the lead-acid battery with equivalent usable capacity.


    • Third, because of incompatible communication protocol, when powered by third-party batteries, the ePropulsion motor cannot access real-time battery status and apply the best operation strategy.


  • Despite all these, if you still prefer third party lithium or lead-acid batteries. The nominal battery voltage should be 48V. The continuous discharge current should be over 62.5A for Navy 3.0 Evo and 125A for Navy 6.0 Evo.

The Evo top mount control has a built-in battery and it can be self-powered by its solar panel. When you use it with wireless connection and the control is at low battery level, you can charge the Evo top mount control with a communication cable.
