It operates well in cold climates and Fish Finder Battery extreme weather and packs a powerful punch when starting the engine making it an ideal choice for those in temperate climes. It also promises fifteen times vibration resistance for durability. 100 Amp hours (Ah) of capacity is optimal for larger 24V trolling motors. When it comes to marine batteries or trolling motor batters, you have your typical 12-volt lead acid batteries, AGM (or Gel Mat) batteries and you have lithium batteries (LiFe PO4). These can be used to start an outboard, power lights and pumps, power multiple electronics and fish finders and run a 12, 24 or 36-volt trolling motor. One of the key components are that the batteries are waterproof.

These batteries are great if you are looking for a reliable battery that delivers constant results for you. Some companies offer ten-year warranties, some provide lifetime warranties, and some only offer two or three months. You want to make sure to protect yourself and go for a battery with a decent warranty. Even though batteries may seem like a simple and straightforward purchase, if you want to find the perfect one for you and your boat – there are a few things you should know. In this article, we’re going to cover all the critical factors that make a great trolling battery.

Otherwise, you may end up buying new batteries which is more costly. The batteries are also tightly sealed to ensure that the fluid inside does not leak. And finally, the batteries come with a 3-year warranty which is pretty great since many similar products come with a shorter warranty.

A deep cycle battery won’t crank engines but offers more efficient deep cycling, meaning the battery will last significantly longer than a dual-purpose battery. This battery should also be safer to discharge, as it can handle deeper discharging compared to dual-purpose batteries. Absorbed glass mat (AGM) batteries are considered an upgrade on wet cell batteries. They offer a longer-lasting battery while also a much longer lifespan, usually lasting 3-4 years, while no maintenance is required either. A 12-volt, 100 amp-hour battery would last two hours on a trolling motor drawing 50 amps at full power. That said, you probably won’t be pushing your trolling motor at full power for that long.

Once you have wired your trolling motor, it’s important to check your connections to ensure they are secure and tight. Use a multimeter to test the voltage of your battery and ensure it is delivering the correct voltage to your trolling motor. As a general rule of thumb, aim for 2 pounds of thrust per 100 pounds of boat weight regardless of the motor or battery type. For example, a 17-foot boat weighing around 1,700 pounds would require a motor with at least 34 pounds of thrust and a battery type strong enough to run it.

It is a 12 Volt battery with an Amperage 55 AH; the chemical elements are AGM and SLA. It weighs 38.58 lbs, and the dimensions are 9.02 in x 5.43 in x 9.13 inches. Customers have mixed opinions about the battery’s durability, with some praising its quality while others report that it doesn’t last long. 12.8V 10Ah LiFePO4 battery is a best choice for alarm system, off-grid application.

Finally, it has low self-discharge rate, which means it can sit for a year without being recharged. It’s not recommended to leave your trolling motor battery plugged in constantly. While lithium batteries have built-in BMS protections, overcharging or maintaining a full charge for extended periods may reduce battery life.

100ah Lithium Batteries

This 24V battery is bigger than others in the list (20.5 x 9.37 x 8.54 inches and 47.4 pounds) but smaller than other batteries being able to carry 2560 Wh. If you are a trolling fishing enthusiast and you cannot live a season without it, such a battery is a must-buy. You’ll need some protection, or at least covering a battery from direct sun rays. Though it does not need maintenance, in case of damage, you’ll need professional repair that will not be cheap. You need to check them for the electrolyte (acid) leaks that can do a lot of damage. You need to supply these batteries with distilled water as well.

That means it can deliver 100 Ampere hours of current to your trolling motor – so if your outboard draws a steady 20A, this battery would power it for 5 hours. Save time and eliminate the hassle of connecting and disconnecting your deep cycle batteries from your trolling motor with a pre-built wire harness from Connect-Ease. This battery though small packs some good power with 15 amp hours.

How To Pick The Right Lithium Battery

Its dimensions are 10.75” x 6.75” x 9.1” and it weighs roughly 45 lbs. The sealed unit allows the battery to be mounted up to a 45-degree angle without the need to worry about spills and leaks. Unlike other wet acid batteries, it is sealed to prevent leaks and spills making it easy to mount at various angles without worry. The AGM technology helps bind the batteries cells together and contains the electrolytes, therefore, making it spill proof.

For A 24v Motor Requiring 2 X 12v Batteries:

It delivers exceptional power and uses a heavy-duty, calcium-alloy grid that gives great service and performance in marine and cyclic purposes. Hence, it is considered the best trolling motor battery you can buy or worth spending on. Ideally, you need a battery for starting, and a deep cycle battery is required for the trolling motor. However, if there is less space onboard, you can choose one battery depending on the power draw required. In comparison, a deep cycle battery is one that provides continuous power over long periods. Buying a trolling motor battery can be difficult as there are different types of boats.

To run your trolling motor on a 12-volt battery, you need to connect two or more batteries in a series to get the necessary voltage for your trolling motor. Connecting in a series is the engineering term for linking batteries positive to negative, which raises their voltage without raising their amperage. A good rule of thumb is twice your trolling motor battery’s max amp draw. It does depend on how hard you run your trolling motor and how long you need it. Trolling motors draw power for hours, but your boat’s main engine only needs an initial burst of power. Plenty of boat owners can match a battery to their primary outboard engine’s cranking requirements.
