How long does the ePropulsion Spirit 2 battery last on a single charge?

The ePropulsion Spirit 2 battery (Spirit Battery Ultra), is a 1,382 Wh NMC lithium battery. Runtime depends heavily on throttle level, boat weight, wind, and current conditions.

At full throttle, expect approximately 1 hour of runtime. At a comfortable cruising speed (around 50% throttle), runtime typically extends to 2.5–3 hours. If you are sailing and using the Spirit 2’s hydrogeneration feature, the battery can be partially recharged while underway, further extending your effective range.

For greater range, the Spirit 2 can also be connected to an E-series external battery (E60, E100, or E163) via the E-series battery adapter.
