Extract from their web site:

=========================================================
Autonomy

Lithium-ion batteries are currently used due to their high energy density. Other traditional lead batteries and zinc-carbon batteries have a much lower energy density.

Two battery packs to choose from are available for the Magellano 50: a 21 kWh battery pack (range of 5 nm), or a 42 kWh battery pack with a range of over 10 nautical miles at zero emissions.

For a short daily outing of 20 nautical miles, this means an average 50% reduction in diesel consumption (compared to sailing at 7 knots on diesel power)
