Trolling motors use deep cycle batteries, and the car battery (usually the cranking type of battery) isn’t ideal for a trolling motor. For example, if you have a 100 amp hour trolling motor battery, and the motor pulls 40 amps at top speed. The trolling motor battery life should be around 2.5 hours (100 Ah / 40 amps) at top speed.

Best Budget: Interstate Deep Cycle Batteries

Equipped with a 150A BMS, it delivers a 1920W high power output for larger appliances on your boat. Its fast-charging capability allows it to fully recharge in about 2 hours, making it perfect for long days on the water. Customers appreciate the battery’s compact size, noting it’s great for small boats and kayaks, with one customer mentioning it works well with their Minn Kota Endura C2 trolling motor.

Selecting the correct size ensures optimal performance, extending the life of your battery for consistent power delivery. The dimensions are 7.68 x 5.12 x 6.46 inches, and it weighs only 22 lbs. Not only is this lightweight, compact, but it is also cost-effective, best suited as a small trolling battery. It has a patented sealed post that prevents any corrosion and gives extended battery life. This is a deep cycle battery of 12 volts from Interstate Batteries.

Thermal runaway protection is critical—look for multi-layer separators and flame-retardant electrolytes. Battle Born Batteries and Dragonfly Energy models exceed ABYC E-11 marine electrical standards. Always install in ventilated, waterproof battery boxes with circuit breakers. The battery is also shock-resistant, meaning it can withstand the bumps and vibrations of trolling without losing power or performance.

100ah Deep Cycle Trolling Motor Battery Set

By comparing different batteries on this chart, you can identify the best battery size for your application based on the trolling motor thrust. In the battery charts below, we use a rough estimation of how much amp draw occurs at different speeds. The actual amount varies depending on the motor being used, as well as the boat and water conditions. Not only did he go from 5 lead acid batteries to three lithiums, but he went from 300 pounds to 91 pounds in his battery compartment with these Impulse Lithiums.

Customers find the battery performs well with 30lb Minn Kota trolling motors and lasts all summer, with one customer reporting it runs for 8 miles on a single charge. They appreciate its compact size, particularly for small boats and kayaks, and its lightweight design that makes it easy to carry. Customers consider it good value for money and praise its power, with one noting it provides plenty of power for the trolling motor. They find it easy to use, with one mentioning it’s particularly convenient for their Scadden Predator. Deep-cycle batteries are designed to provide continuous power over extended periods, making them ideal for powering trolling motors and supporting marine equipment.

This feature makes this battery incredibly popular among serious anglers on larger fishing boats. This battery has the power to turn over a larger motor among rough waters. They are under warranty for twelve months from the date of purchase. The company recommends checking your charger and panels to ensure they meet the required wattage. If that does not fix your problem, try charging the battery for fifteen hours and reading the voltage meter.

This depends entirely on the voltage of the trolling motor you use. In most cases, trolling motors are 12V so you only need a single 12V battery, which is the most common type available. Always consider the size of the battery before buying it to ensure it’s suitable for your boat. For example, does it offer enough space for larger-sized batteries? If tight on space make sure to choose a battery that is compact enough to fit onto the vessel.

It’s large enough to power trolling motors all day, delivering the thrust you need to fish hard. Trolling motors with 30 pounds of thrust are often found on smaller boats like kayaks and canoes. The following chart shows the run times at various speeds with different battery sizes. They will degrade over time and not put out as much power in the latter years.

It’s best to unplug when fully charged or use a smart charger with overcharge protection. When it comes to powering your trolling motor, settling for anything less than the best is simply not an option. At Tournament Lithium, we understand the crucial role a reliable trolling motor battery plays in your fishing adventures. Our cutting-edge batteries are designed to not just meet, but exceed your expectations, ensuring that your time on the water is always powered to perfection. When it’s all said and done, the boating fisherman really wants two things out of his trolling motor and battery(ies). He wants; 1) To have enough power or pounds of thrust to maneuver his boat in any circumstance, and 2) To have enough battery life to easily cover his sessions on the water.

To determine the best battery for a trolling motor, we looked at construction, performance, and cost. Bouncing around in a boat and rolling through waves, a marine battery takes a lot of abuse. A deep cycle battery with beefy lead cells and a sturdy case will avoid damage and corrosion. We also compared batteries from many manufacturers for the longest reserve capacity, highest cold-cranking amps, and best recharging profile. A flooded battery is also known as a wet cell deep cycle battery. Using lead plates separated by spacers and immersed in a solution of sulphuric acid and distilled water, the heat generated is dissipated through conduction with the water.

Customers report positive experiences with the battery’s performance, noting it lasts all summer and can run for several hours. One customer mentions it can power a trolling motor for 8 miles on a single charge. If the result falls below the minimal threshold, a replacement is necessary to prevent a dead battery. Employing a reliable battery charger and consistent testing can reveal issues early on, reducing the chance of severe problems. Be cautious of fast charging, which can boil the water out of the battery and cause damage.

As you can see, choosing a lithium battery is an investment to consider. You need to pay a lot, but you get reliable equipment that will work for you for many years. On the other hand, you need to save money on high-quality equipment, which excludes fast decisions.

You can’t usually ship wet cell batteries, so you’ll have to pick these up in-store. This VMAX battery is rugged and capable of withstanding pretty extreme conditions. Reviewers note that the battery holds a good charge and lasts long enough to stay on the water all day.

It’s impressive how good my screen looks and how it’s good all day. We spent a lot of time testing their batteries in a variety of situations from powering electronics, starting an outboard and powering a trolling motor. Their battery management system (BMS) is very well designed, and we never encountered the first problem.
