Spare Battery | Sea Walker S1500 48V 

Extend your range with a second battery - 60 min

The Sea Walker S1500 spare battery is designed for users who want more autonomy from their electric outboard motor. Instead of waiting for a recharge between trips, you can carry a second battery and swap it when needed.

With a capacity of 1600Wh, this 48V lithium battery is suitable for the Sea Walker S1500 electric outboard and helps extend your runtime for tender trips, marina transfers, short coastal runs and repeated use during the day.

Lightweight and easy to handle

At approximately 9 kg, the battery remains easy to carry, remove and install. This is important for tenders, inflatable boats and users who transport the motor and battery separately after each outing.

Designed for practical electric boating

A spare battery is one of the most useful accessories for an electric outboard. It gives more freedom, reduces range anxiety and allows you to adapt your setup to the day’s navigation: short tender runs, repeated harbour transfers, quiet coastal use or low-speed cruising.

For best performance, always charge the battery with a compatible Sea Walker charger and store it in a dry, protected place when not in use.
