LiTime, and ECO-WORTHY offer more affordable lithium batteries in the $250-$350 range. They offer decent lifespans for the price.
On the other hand, Dakota offers the best selection of lithium battery capacity levels.
If your budget is tight, then you may consider also AGM batteries from Renogy and Weize.
In terms of capacity, all the batteries listed offer 100Ah and the voltage is 12V for all models. However, they are also available with lower capacity and higher voltage if needed.
The Battle Born is very robust, but also the heaviest lithium battery at 31 lbs, while the other LFP batteries range from 19-26 lbs for easier mounting and transportation.
Overall, Battle Born is the premium quality choice, made in the USA. While the others provide a more affordable choice.

How to Choose Battery Power and Capacity
Selecting the right battery size and power output is crucial for optimal trolling motor performance. Here are the key factors to consider:
Motor Thrust and Voltage
Match your battery configuration to the voltage (12V, 24V, 36V) and thrust rating of your motor. Higher thrust motors draw more amps and require more battery capacity.
Consider the typical runtime per fishing trip and choose enough battery capacity to meet your needs with a 20% safety buffer. Longer runtime requires more battery capacity.
To calculate the hours of runtime you can use the formula below:
Battery Wh / Trolling Motor Watts = Hours of run time
Check the Watts used by your trolling motor, then simply divide the battery’s Wh by the Watts used by your motor. This will give you the approximate running time of your trolling motor with that battery.
Peak Amps vs. Reserve Capacity
Peak amps provide starting burst power while reserve capacity indicates runtime at a steady discharge rate. Choose batteries with high reserve capacity for trolling motors.
Battery Quantity and Position
The number and placement of batteries affect performance. More distributed weight improves boat handling. Optimal configurations depend on your specific boat.
Colder temperatures degrade battery performance. Choose batteries able to withstand seasonal temperature fluctuations in your fishing environment.
The C-rating indicates the maximum current, in amps, that a battery can sustain. Most quality 100Ah lithium batteries have a 100A (1C) continuous rating. Higher C-ratings around 3C-5C allow powering high-draw devices like large motors or inverters.
Low Temperature Charging
Lithium batteries can be damaged if charged below 32°F (0°C). Quality batteries have a low temperature cut-off to stop charging in cold conditions. This feature is essential for cold weather use.
Some batteries have Bluetooth connectivity allowing monitoring of voltage and state of charge from a phone app. This convenient feature lets you check battery levels at a glance.
Battery Management System
A good BMS protects the lithium cells from damage due to overcharging, short circuits, high temperatures, and other issues. The BMS is essential to battery safety and longevity.
Lengthy warranties of 5-10 years provide peace of mind. However, read the fine print carefully as some warranties have pro-rated periods or may not cover certain types of damage.
Lithium batteries are 50-75% lighter than comparable lead acid batteries. Reduced weight improves performance and handling.
There is quite a range when it comes to lithium battery pricing. Typically $300 to $900 for a 100Ah battery, and around $70 if you just need a small 20Ah battery. I recommend focusing on quality and performance rather than just the lowest cost.
Regarding AGM batteries instead, those are typically more affordable, ranging between $150 and $300.
Lithium vs Lead Acid Batteries
Here is a comparison of how lithium batteries stack up against traditional lead acid batteries:
Types of Batteries for Trolling Motors
There are 3 main types of trolling motor batteries:
- Flooded Lead-Acid Batteries: The most affordable option but require routine maintenance to check water levels. Can spill acid if tipped over.
- Absorbed Glass Mat (AGM) Batteries: More expensive but sealed and spill-proof. Don’t require water refills. Heavier than lithium.
- Lithium Batteries: Most expensive upfront but lightest weight, longest lifespan, highest performance. No maintenance is required.
Lithium vs AGM Batteries
The best trolling motor battery provides long-lasting power, charges quickly, withstands temperature extremes, requires low maintenance, and gives you the freedom to go for long distances.
Lithium batteries for trolling motors check all these boxes and are the best long-term investment for most boaters, sailors, kayakers, and fishing enthusiasts.
Lithium batteries pros and cons VS lead acid batteries:
|Capacity||High energy density||Low energy density: storing less energy in the same space|
|Lifespan||Longer lasting: 10 years||Shorter lifespan: 2-4 years|
|Weight||Lighter: up to 70% less weight||Heavier|
|Charging Time||Faster charging||Slow charging|
|Maintenance||Less maintenance||Requires more maintenance if FLA|
|Cost for 100Ah||300-1100$||200-350$|
|Performance||High DOD (Depth Of Discharge): up to 95%||Low DOD (Depth Of Discharge): you can use only about 50% of the stored energy|
Overall, lithium-ion batteries have a higher energy density, longer lifespan, faster charging time, lighter weight, lower maintenance requirements, and are better under heavy loads. However, they are more expensive.
Lead-acid batteries have a lower capacity, shorter lifespan, heavier weight, and lower performance but are less expensive and might require periodic maintenance.
NOTE about lithium batteries: make sure to have the right battery charger for this type of battery. Also, if you are charging from solar, make sure that your solar controller is set up to charge this type of battery, or you may face issues.
Helpful Features for Trolling Motor Batteries
Look for these helpful design features when shopping for your next trolling motor battery:
Maintenance-Free AGM or Lithium
AGM and lithium batteries eliminate the need to check fluid levels, reducing maintenance.
Convenient meters show the real-time charge state, ensuring you head in before running out of juice.
Space can be tight on small boats. Compact batteries fit into tight spaces and keep weight centered.
A rubberized coating cushions the battery from vibration and accidental impacts for longer life.
Pre-installed mounting straps make secure battery installation quick and easy.
Batteries with lower self-discharge preserve energy better during storage between uses.
Choosing the right battery is essential to powering your trolling motor and enjoying full days of fishing on the water.
Flooded lead-acid, AGM, and lithium batteries all have their pros and cons. Determine the required capacity based on your motor’s power draw and runtime needs. Also, if you are planning to use your trolling motor in a marine environment, then you should check my other article!
Helpful features like built-in battery meters, rubberized protection, and low self-discharge extend battery life and usability.
For unmatched performance and durability, I recommend the Battle Born batteries. But budget-friendly options like the LiTime Mini delivers reliable power at a lower cost. In addition, you will be able to use those batteries also in your RV.
