This is because higher voltage motors draw less current from the battery to achieve the same level of thrust or power compared to lower voltage motors. With lower current draw, the battery's capacity is utilized more efficiently, resulting in extended runtime.

For example, a 12V trolling motor will typically have a higher current draw compared to a 24V or 36V motor when operating at the same level of thrust. This higher current draw puts a greater strain on the battery, causing it to be depleted more quickly and resulting in shorter runtime. When choosing the voltage for your trolling motor, it's essential to consider the battery capacity as well. A higher voltage motor may require a battery with a larger capacity to maintain an optimal runtime. Additionally, the battery's state of charge and health also affect the overall runtime of the trolling motor.

It's worth noting that factors like wind, current, boat weight, and speed settings also impact the runtime of a trolling motor. Operating the motor at higher speeds or in challenging conditions will increase power consumption and reduce runtime, regardless of the chosen voltage.

To maximize the runtime of a trolling motor, consider the following tips:

• Choose the optimal voltage for your boat size and fishing needs.
• Select a high-quality battery with sufficient capacity to match the motor's voltage.
• Ensure the battery is properly charged and well-maintained.
• Operate the trolling motor at lower speeds when possible to conserve power.
• Minimize unnecessary stops and starts to avoid additional power consumption.

By considering these factors and implementing proper battery management practices, you can ensure longer runtime and enjoy extended fishing trips without worrying about running out of power.
