For travelers and workers who are often out fishing, the most important thing they have to consider with a trolling boat motor is the battery. Some motors come with batteries, but most require us to purchase marine trolling battery separately. Marine trolling battery will have a significant impact on the motor performance of the trolling motor and, by default, will also have a significant impact on the traveler's kayak experience.


How do you choose the best marine trolling battery?

The size of the trolling motor battery i.e. boat trolling battery or boat starter battery depends on everyone's needs. Typically, it comes in 12v, 24v, and 36v configurations. 12V motors require 12V batteries, while 24V motors require lithium trolling motor batteries 24V or 2 (12V) batteries.


In addition to voltage, it is important to consider the amp hours of the marine trolling battery and how long you plan to run the motor. For example, if a 12V motor draws 60 amps at maximum speed and you plan to run it for 2 hours at that speed, you will need a battery with a capacity of 120 amp hours. However, for longer battery life, it is wise to select a battery with a slightly larger capacity than your calculated needs.


However, for longer life and efficiency, it is recommended that you select a battery with a slightly higher capacity.


Analyze the size of boat trolling battery you need if you look at the usage patterns. It can be categorized into two types. One corresponds to recreational anglers only, whose fishing expeditions are sporadic and take place mainly in calm waters, then a 12V 50Ah battery will suffice, it's both compact and ample. And for the professional or enthusiastic angler who often takes frequent, extended trips in rough waters? A 100V or 200V battery with higher Ah (e.g. 24Ah or 36Ah) becomes essential. The POWERWIN BT200 12V 200Ah battery, for example, not only ensures longevity, but also provides fast engine starting, a key feature when away from the shore.


So in summary if you're picking between different types of batteries. 12V batteries would be better suited for smaller boats like kayaks or canoes where space and weight are at a premium. The 24V and 36V batteries, on the other hand, are designed for larger boats and challenging aquatic conditions, and provide a powerful source of power to ensure that the marine starting battery doesn't run down under demanding conditions. For 20V motors drawing 24A per hour, the 24V 60Ah battery provides 3 hours of optimal run time.
