Are you in the market to buy the best lithium battery for trolling motors? Do you know the best types to select? Regardless of your answer, there is a lot to know before you pick the best batteries.

The battery you choose for your trolling motors is integral to meeting your needs. Besides the power settings you RV or boat is using, the run time of your trolling motor will depend on the type of battery you choose. Whether to choose lithium or lead acid batteries is a widely debated issue on many platforms.

Understanding the main difference between these two popular battery types will help make the right decision. Continue reading to learn more.

Lithium RV and Lead Acid Batteries- Key Things to Know

Both batteries serve the basic function- to provide enough power to your RV for a long period of time. In addition, the batteries are designed to discharge needed power until they are empty and recharged. On the other hand, there is a lot to look at that differentiates these RV batteries.

Lead Acid Batteries use flat plates of lead immersed in an electrolyte. The depth is good enough to store a charge and provide power in RVs. Different lead batteries have been released, including flooded lead acid batteries, gel batteries, and absorbed glass mat batteries.

RV lithium batteries, also popularly known as lithium-ion batteries, use metal lithium instead of lead metal. There are different types in the market, but the best option for RVs will be a lithium iron phosphate battery.

Lithium RV Battery vs Lead Acid RV Battery

Here is the main difference between a Lithium battery for RV and a lead acid battery:


RV lithium batteries stand out above lead acid batteries as they provide more power for longer. In addition, lithium batteries will provide 80% of their capacity before you recharge them. A lithium battery will recharge more quickly than similar lead-acid RV batteries.


RV lithium batteries will also win regarding their lifespan, measured in terms of the number of times they can be discharged and discharged. A lead acid RV battery lifespan will be in the hundreds range. Some lead batteries will have as few as 300 cycles, while only a few batteries will reach over 1000 cycles.

On the other hand, a lithium battery for RV will provide thousands of cycles over its lifespan. Some of the lithium-ion batteries will deliver over 5,000 cycles.

In simple terms, RV lithium batteries will last more than 10 years, while a lead acid battery will last two to five years.


Lithium battery for RV is much lighter than a lead acid RV battery. The weight difference comes in because of the lithium-ion batteries’ higher energy density. In fact, a lithium battery will be half the weight of a lead-acid battery.


Lead acid batteries are a winner when it comes to cost. They will cost less than RV lithium batteries. A lead acid battery might cost between $200 and $700, depending on its size and type. On the contrary, a lithium-ion battery cost will start at $900 and surge with the increasing demand.

In Conclusion

When looking for the best battery for your RV, it’s wise to compare lithium or lead acid models. The key difference between these batteries is the material that they are made out of and their matchless features. RV lithium batteries are more expensive, efficient, and have a higher capacity than lead-acid batteries. If stuck, it is advisable to research widely, consult experts, and seek recommendations on the best batteries to choose for trolling motors.
