Spare Battery only. No Charger Unit included


Extra batteries come in handy when you're out on the sea away from a power outlet and want to double the length of ride time. Simply purchase a spare battery and ride for twice as long without needing to come in and recharge.

The HydroFlyer™ is powered by a supercharged advanced lithium-ion battery. Built robust to handle the toughest of ocean conditions, it is the most powerful electric battery for its size available today.

This is one of the most advanced batteries to ever power an eFoil. Battery life is up to 120 minutes of ride time depending on conditions and riding style.

For general use most people get around 3-4 hours.
