Frequently Asked Questions

Is the Spirit 2 Battery Ultra compatible with the ePropulsion Spirit 2?

Yes. The ePropulsion Spirit Battery Ultra is the dedicated battery for the Spirit 2 electric outboard series. It is designed specifically for the Spirit 2 system and is compatible with Spirit 2 Extra Shortshaft, Shortshaft, and Longshaft configurations.

Can I use the Spirit 1.0 Plus battery with the Spirit 2?

No. The Spirit 2 uses the new Spirit Battery Ultra, which is not interchangeable with the battery used by the Spirit 1.0 Plus. The battery connections and mounting system are different, so the Spirit 1.0 Plus battery cannot be installed on a Spirit 2 outboard.

How long does the Spirit 2 Battery Ultra last on a single charge?

Runtime depends on your boat, total load, speed, throttle setting, wind, current, and water conditions. For this reason, there is no single runtime figure that applies to every setup. Lower power settings generally provide significantly longer operating time than running continuously at higher power.

For the most accurate estimate, consider your boat and typical operating conditions rather than relying on a single advertised runtime number.

How long does it take to charge the Spirit 2 Battery Ultra?

Charging time depends on the charger being used. The Spirit 2 Battery Ultra can be charged separately from the motor, allowing you to remove the battery and charge it in a suitable location. Charging options may include the standard AC charger as well as compatible 12V and solar charging solutions.

Always use a charger specifically designed and approved for the Spirit Battery Ultra.

Can I charge the Spirit 2 Battery Ultra with solar power?

Yes. The Spirit 2 Battery Ultra can be charged using solar power with the appropriate ePropulsion Solar Charge Controller. This can be useful for extended trips, sailing, camping, and other applications where access to shore power is limited.

Can I use an external battery with the Spirit 2?

Yes. The Spirit 2 can be powered using compatible external batteries with the appropriate ePropulsion external battery cable. This provides an option for boaters who need more energy capacity or longer operating time than the Spirit Battery Ultra can provide.

Compatible ePropulsion E-Series batteries and certain compatible 48V third-party batteries may be used, provided they meet the required specifications. Always confirm battery and cable compatibility before connecting an external battery to the Spirit 2.

How do I check the charge level of the Spirit 2 Battery Ultra?

The Spirit Battery Ultra has a built-in state-of-charge indicator that allows you to check the battery level directly from the battery. The Spirit 2 system can also provide battery information through its onboard display when the battery is connected to the motor.

How should I store the Spirit 2 Battery Ultra when I'm not using it?

For long-term storage, keep the Spirit 2 Battery Ultra in a cool, dry location away from direct sunlight and extreme temperatures. Avoid storing the battery completely empty or fully charged for extended periods. Follow the ePropulsion Battery Ultra user manual for the recommended storage charge level and temperature range.

Proper storage helps protect the battery and maintain its performance between boating seasons.
