We recommend the E80 battery for Navy 3.0 Evo, and E175 battery for Navy 6.0 Evo. Other configurations can be created, but parallel connection is required.

To power a Navy 3.0 Evo with E40, you need two E40 batteries in parallel. To power a Navy 6.0 Evo with E80, you need two E80 batteries in parallel.

Our original E-Series battery has the best unit price on the market, as low as $0.46 per WattHour.

The E-Series battery weighs 70% less than the lead-acid battery with equivalent usable capacity, and costs 50% in five-year use.

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

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