Marine & Trolling Motor FAQs

Check voltage, runtime, charging and installation requirements before choosing your marine battery.

Start with the trolling motor voltage and current draw, then choose Ah capacity based on your required runtime.

Yes, if the motor is designed for a compatible 12V lithium battery and the battery can supply the required continuous current.

Use a compatible 24V-class battery system. Do not assume two batteries can be connected in series unless that configuration is specifically supported.

Do not use a deep-cycle battery as a starter battery unless the model is specifically rated for engine starting and provides the required cranking specifications.

Check the specific IP rating and installation requirements. An IP rating does not automatically mean the battery is suitable for immersion or unrestricted exposure to water.
