Aerofoils Audi e-tron eFoil Endurance Battery

Aerofoils Audi e-tron eFoil Endurance Battery — Overview

At the heart of the Aerofoils Audi e-tron eFoil sits a 2.23 kWh lithium-ion battery — the Endurance Battery. With 13 kg and 44.25 Ah of capacity, it delivers the longest range available for the platform: up to 120 minutes of riding time or 40 km on a single charge.

The Endurance Battery is fully recharged in just 2 h with the Fast Charger 1200, or in 3 h 30 min with the Standard Charger 600. A gentle charging mode via mobile outlets or a slow-charge circuit reaches full capacity in 5 h 30 min — perfect for overnight charging or when running multiple chargers on the same grid.

2.23 kWh — Maximum Range

The largest battery in the Aerofoils Audi e-tron eFoil platform — double the capacity of the Light Battery. The right choice for distance riders, charter operators and full-session use.

Up to 120 min / 40 km Riding Time

Real-world riding time depends on rider weight, speed and conditions, but the Endurance Battery delivers up to 120 min or 40 km on a single charge.

Fast-Charger Ready in 2 h

With the Fast Charger 1200, full charge takes just 2 h (80 % in 1 h 20 min). With the Standard Charger 600, expect 3 h 30 min; gentle charging from a mobile outlet takes 5 h 30 min.
