FAQ
Q: How to Choose the Right Capacity of Trolling Motor Batteries？
A: The capacity of the lithium battery required for a trolling motor depends on several factors, including the thrust rating, duration of use, and the environment in which it is used.
Thrust Rating:
- 50-55 lbs thrust:Typically, a 12V lithium battery with a capacity between 50Ah and 100Ah is sufficient.
- 55-80 lbs thrust: A 12V lithium battery with a capacity between 100Ah and 125Ah is generally recommended.
- 80 lbs and above thrust:You may need a 24V or 36V system with a capacity of 100Ah or more.
Duration of Use:
- For extended use (e.g., 8 hours or more), consider a higher capacity battery to ensure you don’t run out of power during your outing.
Environment of Use:
- If you often run your motor at maximum power, use spot locks frequently, or fish in strong currents or windy conditions, you'll need a battery with at least 100Ah capacity.
Common Configuration Options:
- 12V 50Ah to 100Ah lithium batteries:Suitable for small to medium-sized trolling motors and short to moderate use.
- 12V 100Ah to 125Ah lithium batteries: Ideal for medium to large trolling motors and long or intensive use.
- 24V or 36V systems: Best for large trolling motors or applications requiring longer range and extended power.
Q: Do I need to fully charge my newly purchased trolling motor batteries before using them?
A: When you purchase a new lithium trolling motor battery, it typically comes charged to about 50% to 60% for safe transportation and storage purposes. Lithium batteries are not affected by memory effects, so they can be used at any charge level. If you're only testing the new battery briefly or using it for a short distance, you can use it directly. However, if you plan to use it extensively at sea, it's recommended to fully charge the battery beforehand to ensure sufficient power.
Q: How long does it take to charge 12.8V 100Ah lithium trolling motor batteries?
A: Battery charging time depends on the capacity rating of the battery and the output of the charger. For example, if a 12V lithium charger is rated at 15 amps, then you can fully charge a 12V 100Ah battery in approximately 6 hours.
Q: Do lithium Trolling Motors batteries require a charger that is professionally configured？
A: Lithium batteries possess unique charging characteristics. Professionally configured chargers typically incorporate safety features like temperature monitoring, overcharge protection, and balancing functions to safeguard the battery during charging. Utilizing a charger specifically designed for lithium batteries prevents overcharging or undercharging, thereby preserving optimal performance and capacity throughout its lifespan.
Q: What battery does a trolling motor need?
A: LiFePO4 trolling motor Batteries are the best choice for trolling motor batteries, depending on the size and type, a 12 V deep cycle battery with 100ah or more. The higher the amp-hour rating, the longer the trolling motor will run.

A: LiFePO4 batteries have the longest life of any deep-cycle battery. In the current market, LiFePO4 batteries are the most in-demand trolling motor battery for any crew or angler.
Q: How long will a 12V 125Ah LiFePO4 battery last when using a trolling motor?
A: For example, if your trolling motor draws 10 amps per hour and the deep cycle battery is rated for 125ah, that means you can run your trolling motor for 12 hours.
Q: What size lithium battery is the best choice for trolling motor batteries?
A: If we need a trolling motor with a kayak, a smaller lithium trolling motor battery can be used (e.g. 12V 50Ah or 12V 80Ah battery). If you need a battery as light and small as possible, with a high energy density, then the advantages of lithium batteries are significant.
Q: What size battery do I need for a 55lb thrust trolling motor?
A: Considering the physical power of the trolling motor and the number of batteries selected, if the motor has a maximum thrust of 55 lbs, （1） 12V lithium battery. If the maximum thrust is 80 lbs, you will need（2）12-volt batteries for a total of 24 volts.
Q: Can my trolling motor batteries be replaced with a car battery?
A: Adopt a deep-cycle or marine battery; the LiFePO4 battery is a good choice.
Q: What problems will lithium trolling motor batteries cause if I use the wrong charger?
A: Lithium batteries can be damaged if the wrong charger is used， the voltage and current do not match; using a special charger is safer, and can also charge the lithium battery more quickly.
Q: Can trolling motor batteries overcharge?
A: Lithium-ion batteries contain a lithium-ion membrane for higher energy, higher safety, and a built-in BMS to protect the battery from overcharging and over-discharging and to maximize the cycle life of the battery.
Q: Is it best for me to keep my Li-Ion batteries fully charged and in a fully charged state?
A: If you plan to store the lithium battery and not use it for a long period, recommending to keep the lithium at a charge of about 50% or so. If you
frequently fully charge the battery before storing it, it may cause the battery's performance to deteriorate.
Q: Is it okay to leave lithium trolling motor batteries connected to the charger overnight?
A: Generally speaking, it is safe. However, please keep it in a cool, dry place to avoid overheating the generator, and unplug it when not in use.
Q: How often should the Trolling motor batteries be recharged when not in use?
A: We recommend that all lithium batteries that are not in use undergo a complete check and maintenance cycle at least once every 3-6 months to check the charge level (typically 40-60%) and recharge appropriately to maintain a certain level of charge that will prolong the life of the battery.
