Are Lithium Batteries Good for Trolling Motors?
If you are considering a lithium battery for your trolling motor, then you are on the right track. There are a ton of options out there for different marine batteries, but the most popular products that people are choosing are generally best deep cycle batteries are either lead acid or lithium. In this article we will outline the advantages that we feel make a lithium iron phosphate battery the best battery for trolling motors.
Advantages of Lithium Batteries for Trolling Motors
Lithium iron phosphate batteries boast an all around better experience than lead acid batteries. When compared to lead acid batteries, lithium batteries actually come at a better, lower cost per cycle. If you are considering a lead acid battery because it is cheaper in price then a lithium model, then you probably haven’t considered the longer lifespan and overall better performance. Below we will outline all of the reasons that lithium iron batteries are the best choice for trolling motors.
When you are out on the water, every bit of weight counts in order to maximize the life and performance of your trolling motor battery. For 100 amp hour models, the average lead acid battery weighs about 60 lbs. A similar sized lithium battery, on the other hand, only weighs roughly 24 lbs. By more than halving the weight of your battery, your trolling motor will be able to perform better and use less energy. As a bonus, you’ll have an extra 36 lbs of room for your daily catch!
If you are tired of checking the water levels of your lead acid battery, switching to a lithium iron phosphate battery will put an end to your sorrows as there is no maintenance required. If you set out on your marine adventures early in the morning, the fewer chores you must complete, the better, so lithium batteries seem like an obvious choice.
Lithium batteries do not release hydrogen gas, which causes corrosion of lead acid batteries, especially in marine settings. Installing a lithium iron battery on your trolling motor will also greatly reduce the amount of time you will have to spend cleaning battery corrosion to ensure battery longevity.
Longer Lasting Life
Most trolling motor owners replace their lead acid battery every 3 to 5 years. Lithium batteries tend to last between 7 to 8 years. This extraordinary difference actually brings the cost per cycle of lithium batteries below that of lead acid batteries. Typically, the cost per cycle of a lead acid battery is $0.67, whereas a lithium iron phosphate battery’s cost per cycle is closer to $0.31.
We’ve all done it: forget to charge your trolling motor battery before a big fishing trip. Lithium iron batteries help reduce this pain point. Lithium iron batteries typically charge to full capacity in between 1 to 3 hours. Compared to a lead acid battery which has an average charge time of between 8 and 12 hours, the difference is undeniable.
More Potential Usage
Once your battery is charged and you are using your trolling motor, a lithium will outperform a lead acid battery every time. In addition to operating on average at a 25% more efficient level, lithium iron batteries are able to use their entire amp hour storage without causing any damage to the system. Lead acid batteries can generally only use around 55% of the total amp hour storage. This added capacity can lead to less time charging your battery and more time out on the water.
