A great way to determine how Fish Finder Battery much battery charge is provided by the Ah is by measuring it against the amp draw of your motor. For example, if the motor uses 25 amps at high speed, a 100 Ah battery would last four hours. To calculate the run time of a battery with your trolling motor, divide the battery’s amp-hour rating by the trolling motor’s max draw. Battery technology has come a long way in the last several years, and that includes plenty of advances for boat batteries.
The main battery of the boat should also be reserved for cranking and is designed to start with low amperage. As the battery for the trolling motor will require regular discharge and recharge when compared with the main boat battery it allows the main boat battery to last longer. Any common deep cycle battery may vary between 60 and 70 pounds. And by choosing the lithium-ion trolling motor battery, you can reduce the weight but only at a higher price. Overall, the Odyssey Trolling Thunder battery is an excellent choice for those looking for a high-quality trolling motor battery that will provide reliable power and performance. For a 55lb thrust trolling motor, a 12V 100Ah battery is typically sufficient for most recreational uses.
Pound-for-pound, lithium marine batteries have more energy capacity than lead-acid batteries. That means, along with any other benefit from a high-powered battery, it’s lighter than a pack of lead-acid batteries. You can carry more equipment without worrying about how much weight and space it takes to power it all.
Unless you have a high-end motor then you’ll probably have a 12V motor, so most trolling motor batteries have a suitable voltage to power your motor. Actually, ODYSSEY manufactures its batteries out of two plants – one in Missouri and the other in Wales in the UK. Durability is important for any trolling motor battery and this model has it in spades. Being an AGM battery means it’s completely sealed so it won’t leak while being more resistant to vibrations.
Why Is Thrust Important?
You’re limited in how much power you get, taking away some potential of your boating accessories. A deep-cycle battery can run for an extended time and consume only a small amount of energy. The higher the amp hours (capacity of your battery), the longer your battery will perform. These include a longer lifespan, higher cycle life, and better resistance to vibration and shock. AGM batteries are also maintenance-free, meaning you won’t have to refill them like a Lead-Acid wet cell.
At the same time, you are warned that if you run your motor at high speed (over 85%) for a long time, it could damage your motor. Many lithium batteries are rated at 1c, which means the maximum discharge current is equal to its capacity. For example, a 60Ah lithium battery can be discharged at 60 Amps. A lithium battery can keep your trolling motor at the same speed for almost twice as long as lead-acid batteries of the same rated capacity. Today, we discuss the pros and cons of having lithium batteries on board and what you should know before buying one. We also review popular LiFePO4 batteries used with trolling motors today.
For 24V/36V systems, connect multiple 12V batteries in series using marine-grade wiring. Each trolling motor will be fitted with a 12v AGM deep cycle battery, with low hours of power supply over a long time. CCA rated batteries are cheaper than deep cycle units and they will power your trolling motor but not for long. They are designed to provide large amounts of power over a short period (to start an engine).
Our Picks For Best Marine / Trolling Motor Batteries
You can use them to power a scooter, hoveround, wheelchair, and other electronics. And they are popular with anglers because they are reliable, and they cost next to nothing to maintain. So this is a battery you can rely on to give you years of service. Some say it can last up to 8 years, which is incredibly impressive. It is also used to power solar power systems because of its high performance. The best online fishing resource to learn and stay current on the latest fishing gear, news, techniques, trends and more.
Lead Acid Wet Cell batteries are the oldest and most commonly used type of battery for trolling motors. They are relatively inexpensive, widely available, and have a long history of reliable performance in a wide range of applications. The lithium trolling motor battery has the lightest weight, the longest run time and lifespan, and therefore will be replaced less often.
If you use your trolling motor at lower speeds, you will have a significantly lower current draw and much longer run time. They have a maximum discharge current of 100A, which is well above what trolling motors need. Throughout this article, we’ve covered four different types of batteries. Car batteries, Sealed lead acid deep-cycle, absorbed glass mat deep-cycle, and lithium-ion deep-cycle. We’ve digested the pros and cons of each and why they would be a good fit or not such a great one.
Leakproof and maintenance-free, this Universal Power Group battery will keep working when many others fail. Charging is quick and easy, so simply charge it after each use. You can also charge onboard the vessel too if you have a portable charger or solar panels. Always monitor charging and avoid overcharging as this can damage the battery.
These are widely available and effectively require no maintenance. They’re heavy, but you’re getting value in all of those pounds. You also get the proven imprimatur of Bass Pro Shops behind them – that includes a really good warranty if something should go wrong, although you almost certainly won’t. They have lots of power and you can mix and match them for both starting and deep cycle purposes.
What many folks don’t know is that 36V controllers are made to work in 36V environments and give you way more leeway in one battery degrading your whole system. First, you have to understand in parallel or series systems, when one battery goes down, the whole thing is down. If, on the other hand, you want a light and high-performing battery that will last you many years, lithium is the way to go. I recommend you also read reviews and learn about other users’ experiences with customer support. It’s great if you know you can pick up your phone and get any advice you may need. In this case, your motor shouldn’t draw more than 60 Amps, preferably closer to 50 Amps.
