All ePropulsion electric outboard batteries are designed for maximum efficiency, performance and safety. The batteries will discharge themselves and hibernate when not in use to protect themselves, so there is no need for any manual discharging.
The affordable lithium E Series batteries are compact and energy dense and weigh 70% less the equivalent lead acid battery. It is possible to use a 3rd party lead acid battery with the ePropulsion range, although the ePropulsion motor will not be able to access real time battery status. In addition, the E-Series batteries are designed to achieve the most efficient unit price on the market, as low as $0.46 per WattHour.
The Spirit 1.0 Plus and 1.0 Evo electric outboard motors can be connected to the E Series batteries for longer range use, instead of using the integrated electric outboard battery.
Multiple E Series batteries of the same size can be connected in parallel, to increase power output. Each has a different battery management system and cell configuration, hence only the same model can be connected in parallel.
