Can I use E40 to power Navy 3.0 Evo or E80 to power Navy 6.0 Evo?

  • Yes, but parallel connection is required. To power one Navy 3.0 Evo with E40, you need two E40 batteries in parallel. To power one Navy 6.0 Evo with E80, you need two E80 batteries in parallel.

Can I use third-party batteries to power Navy 3.0 / 6.0 Evo?

  • 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, and costs 50% in five-year use.
  • 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.

Do I need to charge the Evo top mount control?

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 could charge the Evo top mount control with a communication cable.

Will Navy 3.0 / 6.0 Evo work for saltwater use?

Yes, it is designed for extensive use in the saltwater. We choose high-quality aluminum alloy as the base material, and apply anodizing coating and powder coating on top of it. For more info, please check ePropulsion Blog: How do we make an outboard corrosion-resistant?
