Trolling Motor Battery Safety

Kayak trolling motor battery
Boat owners should consider important safety measures to ensure the safe and effective use of marine deep cycle batteries.

While marine deep cycle batteries are generally safe when used properly, there are still some important safety considerations that kayak or canoe owners should keep in mind to ensure the safe and effective operation of their marine batteries.

Trolling motor batteries come in a variety of types and sizes. It’s important to choose a trolling motor battery that is appropriate for the size and power requirements of your trolling motor. Using the wrong type of trolling motor battery can not only result in poor performance but can also cause overheating, internal damage, or a fire hazard.

Before each use, it’s important to inspect your trolling motor batteries for signs of damage, such as cracks in the casing, leaks, or corrosion on the terminals. If you notice any issues with your marine batteries, consider having the deep cycle batteries replaced immediately.

When not in use, trolling motor batteries should be stored in a cool, dry place away from heat sources and direct sunlight. Marine batteries should also be stored in an upright position to prevent damage or leaks.

When charging the trolling motor battery, be sure to follow the manufacturer’s instructions carefully. Overcharging or undercharging the trolling motor battery can result in reduced performance or even damage to some lead-acid batteries. Use a charger specifically designed for the type of trolling motor battery you are using.

Always handle the trolling motor battery with care, avoiding dropping or puncturing it. Do not expose the trolling motor battery to open flames or sparks, and avoid using any marine batteries near excessive heat. If the trolling motor battery shows signs of damage or overheating, stop using it immediately.

How to Choose an Electric Trolling Motor Battery

Kayak trolling motor battery (1)
Consider the trolling motor battery’s voltage and amperage requirements to maximize performance and run times.

Trolling Motor Size

To determine the appropriate trolling motor battery size for your canoe or kayak trolling motor, you will need to consider the motor’s voltage and amperage requirements. Most trolling motors operate on either 12-volt or 24-volt systems, with higher thrust motors typically requiring 24 or even 36 volts.

It’s important to choose a marine deep cycle battery that is rated to handle the amperage requirements of your trolling motor, as using an undersized trolling motor battery can result in poor performance and reduced trolling motor battery life. 

Battery Voltage: 12V vs 24V

Trolling motors are typically designed to operate on either a 12-volt or 24-volt system, with larger motors requiring 24 volts to operate.

The size of your trolling motor is the most important factor to consider when choosing between a 12-volt and 24-volt kayak trolling motor battery. Trolling motors with a thrust rating of 55 pounds or higher will require a 24-volt system. Smaller motors with a thrust rating of 30 to 40 pounds can typically operate on a 12-volt system or other compact battery. See here for more info on how to choose what size trolling motor you need.

A 24-volt trolling motor battery will provide longer run times than a 12-volt trolling motor battery, allowing you to stay on the water for longer periods of time without needing to recharge the trolling motor battery.

A 24-volt trolling motor battery will also cost more than a 12-volt kayak trolling motor battery due to its higher capacity and the additional components required to operate a 24-volt system. However, the increased run time and performance of a 24-volt trolling motor battery system may be worth the additional cost for some boaters.

Battery Ah – Amp Hours

The amp hour or amperage hour rating is a measure of the amount of energy a trolling motor battery can provide over a certain period of time. In general, a higher amperage hour rating shown on deep cycle marine batteries indicates a larger trolling motor battery capacity and longer run time.

The amp hour draw is the amount of current the motor will pull from the trolling motor battery when running at full power. You should choose a trolling motor battery with an amp-hour rating that can provide enough power to run your motor for the length of time you need.

To calculate the trolling motor battery amp hour rating needed, divide the amp draw of the trolling motor by the number of hours you need it to run on your trolling batteries.

What Kind of Battery for a Trolling Motor?

Kayak trolling motor battery (2)
AGM and Lithium Iron Phosphate trolling motor batteries are both great options for different needs.

AGM Trolling Motor Battery

An AGM (Absorbed Glass Mat) trolling motor battery is a great battery choice that can be used for a trolling motor of almost any size, including larger trolling motors on fishing boats as well as a small kayak trolling motor.

AGM trolling motor batteries are a type of sealed lead acid battery that uses a glass mat to hold the electrolyte solution in place rather than a free-moving liquid or gel.

AGM trolling motor batteries offer a number of benefits over other kayak trolling motor battery types as the best trolling motor battery, including:

  • Maintenance-free
  • Durability
  • Long lifespan
  • Fast charging

Lithium Iron Phosphate Battery

A Lithium Iron Phosphate (LiFePO4) trolling motor battery is a smaller and lightweight option that can be used as a canoe or kayak trolling motor battery in most cases.

LiFePO4 batteries are a type of lithium-ion battery that offer a number of benefits over other trolling motor battery types as the best trolling motor battery, including:

  • High energy density
  • Long lifespan
  • Fast charging
  • Low self-discharge rate

AGM Trolling Motor Battery vs Lithium Iron Phosphate Battery

AGM lead acid batteries use a fiberglass mat to hold an electrolyte solution, making them a spill-proof and maintenance-free type of lead acid battery. They are relatively inexpensive and provide reliable power for shorter periods of time, making them a good choice for occasional or light deep cycle use.

Lithium Iron Phosphate batteries are a newer technology that offers several advantages over AGM lead acid batteries. Lithium batteries are usually lighter and smaller, making them easier to transport and install. Lithium batteries also have a longer average lifespan and can be discharged to a much lower level without damaging the kayak trolling motor battery.

LiFePO4 batteries are also more efficient than AGM lead acid batteries, which means they can provide the same amount of power with less energy, saving you money in the long run. However, LiFePO4 batteries can be more expensive upfront compared to AGM batteries.

Why Lithium Ion Batteries Aren’t Suitable for Kayaks and Canoes

While Lithium Ion batteries are a popular and efficient choice for many applications, and in most cases are the lightest battery you can find, they are not always suitable for kayaks and canoes due to several factors.

Lithium batteries are typically more expensive than other lightweight trolling motor battery types, such as lead-acid batteries or AGM batteries. This can make lithium-ion batteries cost-prohibitive for many kayak and canoe users who may not need the added performance benefits that lithium batteries offer for their trolling motor or electronics.

Lithium-ion batteries can also be more delicate than other trolling motor battery types, which can be problematic. Kayaks and canoes are often exposed to extreme weather conditions, including high temperatures, which can pose a risk to lithium batteries. This risk can be mitigated with proper care and storage of the kayak trolling motor battery, but it may still be a concern for some users.
