Trolling motors are an essential piece of equipment for any angler looking to navigate their boat with precision and control. These motors are designed to provide a quiet and efficient means of propulsion, making them ideal for fishing in calm waters. When it comes to choosing the right trolling motor for your boat, one of the most important factors to consider is the battery size.
The size of the battery needed for a 70 lb thrust trolling motor will depend on a few key factors, including the type of battery, the motor’s voltage, and the duration of use. In this article, we will discuss these factors in detail to help you determine the right battery size for your 70 lb thrust trolling motor.
Type of Battery
The first factor to consider when choosing a battery for your trolling motor is the type of battery. There are three main types of batteries used for trolling motors: lead-acid, AGM, and lithium-ion. Lead-acid batteries are the most common and affordable option, but they are also the heaviest and require regular maintenance. AGM batteries are a more expensive option, but they are maintenance-free and have a longer lifespan. Lithium-ion batteries are the most expensive but offer the longest lifespan and are the lightest option.
For a 70 lb thrust trolling motor, a lead-acid battery with a capacity of 100-amp hours (Ah) is recommended. This will provide enough power to run the motor for an extended period, and the weight of the battery will not significantly affect the boat’s performance.
Motor Voltage
The next factor to consider is the motor’s voltage. Trolling motors are available in 12V, 24V, and 36V options. The higher the voltage, the more powerful the motor will be. A 70 lb thrust trolling motor typically requires a 24V or 36V battery to operate at its full capacity. However, if you plan on using the motor for short periods, a 12V battery may suffice.
It is essential to note that using a higher voltage battery than what is recommended for your motor can damage the motor and void the warranty. Therefore, it is crucial to check the manufacturer’s recommendations before purchasing a battery.
Duration of Use
The duration of use is another crucial factor to consider when choosing a battery for your trolling motor. If you plan on using the motor for extended periods, you will need a battery with a higher capacity. For a 70 lb thrust trolling motor, a battery with a capacity of 100Ah or higher is recommended for extended use. This will ensure that the battery can provide enough power to run the motor for several hours without needing to be recharged.
It is also essential to consider the charging time of the battery. Lead-acid batteries typically take longer to charge compared to AGM and lithium-ion batteries. If you plan on using the motor frequently, it may be worth investing in a more expensive battery with a shorter charging time.
Other Considerations
Aside from the factors mentioned above, there are a few other things to consider when choosing a battery for your 70 lb thrust trolling motor. These include the weight and size of the battery, as well as its durability and maintenance requirements.
As mentioned earlier, lead-acid batteries are the heaviest and require regular maintenance, while AGM and lithium-ion batteries are lighter and maintenance-free. The size of the battery will also affect the boat’s performance, so it is essential to choose a battery that is not too heavy or bulky.
In terms of durability, lithium-ion batteries have the longest lifespan, followed by AGM and lead-acid batteries. However, lithium-ion batteries are also the most expensive, so it is essential to consider your budget when making a decision.
Conclusion
In conclusion, the size of the battery needed for a 70 lb thrust trolling motor will depend on the type of battery, motor voltage, and duration of use. A lead-acid battery with a capacity of 100Ah is recommended for extended use, while a 12V battery may suffice for short periods. It is crucial to check the manufacturer’s recommendations and consider factors such as weight, size, durability, and maintenance requirements when choosing a battery for your trolling motor. With the right battery, you can ensure that your 70 lb thrust trolling motor runs smoothly and efficiently, providing you with an enjoyable fishing experience.
