Lithium Trolling Motor Battery

VTCBATT lithium trolling motor battery can be deep cycled 4000-15000 times under good use conditions, and its service life can reach 10 years. In contrast, traditional lead-acid batteries usually have a service life of 2-5 years and are larger in mass and volume. The low self-discharge rate of lithium batteries allows them to be stored for a long time without losing power. You only need to pay attention to the storage temperature to maintain a ventilated environment of 10°C to 35°C to ensure the service life of the lithium trolling motor battery.

Compared with other lithium batteries, LiFePO₄ battery has obvious advantages:

• High safety. The stable structure of LiFePO₄ battery enables them to withstand extreme temperature fluctuations and are not prone to fire and explosion.
• Long service life. The 10-year service life far exceeds the life of other lithium batteries, suitable for trolling motors that are frequently charged and discharged every day.
• Environmentally friendly and pollution-free. LiFePO₄ battery does not contain heavy metals such as nickel and can be directly recycled to protect the environment.

When you buy the best lithium trolling motor battery, you should check the voltage to ensure that the voltage is within the normal range. If you have any questions, you can contact VTCBATT to solve it for you. Secondly, check whether the BMS protection function is effective and in normal use. The first time you use it, you must be equipped with a dedicated charger to ensure the life of the battery. If you do not plan to use the lithium ion trolling motor battery for the time being, you need to charge it and store it in a dry and temperature-appropriate environment.

Yes. Our lithium battery trolling motor can be connected in series and in parallel. You need to pay attention to ensure that the lithium battery for trolling motor used has the same brand, capacity and voltage, otherwise it will lead to uneven current bearing, which will cause the risk of expansion and fire.

Our lithium trolling motor battery has excellent waterproof performance. The shell is made of sturdy ABS plastic and equipped with waterproof seals to protect the switch and ports. However, you still need to be careful not to immerse the battery in water for a long time and avoid direct contact with water when installing it.

BMS battery management system. BMS is the core of protecting LiFePO₄ battery. The BMS system can avoid damage to the battery cell caused by overcharge and overdischarge, and can automatically cut off the power to avoid damage caused by high temperature, making the trolling motor lithium battery 5 times longer than other lithium batteries.

Determine the battery capacity. Make sure that the discharge depth matches the battery capacity to reduce the load pressure and ensure the service life.

Pay attention to the actual capacity. Be careful to prevent the purchase of batteries with false capacity. You need to perform actual capacity testing, otherwise improper use will cause premature battery aging.

Correct installation and storage. The location where the battery is installed should be away from direct sunlight and rain and keep good ventilation; storage should be pre-charged and stored in a temperature space of 10°C – 35°C.

Installation Note: The installation location should be away from high temperature and water-immersed locations, and the battery tray, battery box and strapping should be used to properly bundle the battery to protect it from random movement and physical damage. The connection terminals should also be coated with insulating grease to prevent oxidation and corrosion of the metal ends.

Charging management: You should use a special lithium battery charger to avoid the danger of overcharging, and you should still pay attention to disconnecting the charger in time after charging to the appropriate level.

Regular inspection: If the connection part is loose, it will often cause a battery short circuit failure. You should regularly check the tightness of the connector and use anti-loosening washers to stabilize it in time. Problematic parts should be cleaned and replaced in time.

Storage Note: You need to pay attention to the temperature and humidity of the storage environment to ensure the safety of the battery. And you need to regularly check the battery power and replenish it to keep the battery active.

To choose a suitable lithium trolling motor battery, you need to consider the size, capacity and quantity of the battery:

• Battery size and capacity: The greater the motor thrust you want, the higher the current required, and the corresponding battery capacity will also be larger. If you want to operate safely and smoothly on the water, choose a larger capacity battery to ensure endurance.
• Number of batteries. If there are other electronic devices on the boat, additional starting batteries are required to maintain the operation of these devices. The thruster battery uses a deep cycle lithium battery with stable power supply capability. You can connect multiple batteries in series to provide greater power.

Advantages of lithium battery:

Energy density: light weight, small size but larger capacity, so the energy density is very high and cost-effective.

Long life: lithium batteries have a service life of up to 10 years and provide stable power.

Available capacity: has a larger available capacity and deep discharge will not damage the battery.

Weight: 75% lighter than lead-acid battery, extremely light.

Charging speed: can be fast charged and fully charged in a shorter time than lead-acid battery.

Waterproof: we have IP65–IP67 waterproof rating and can be used well in humid environments.

Safety: with BMS protection battery system, it can avoid the risks of overcharging, short circuit and high temperature.

Environmental protection: no harmful heavy metals, acid and gas can be directly recycled.

Advantages of lead-acid battery:

Low cost: lead-acid battery has a lower production cost and is suitable for your project with limited budget.

Simple installation: lead-acid battery can be installed directly without BMS protection system.

Large instantaneous current: Lead-acid batteries have high current in a short time and can be used for high-load tools.

Strong temperature adaptability: The stability in a low temperature environment is better than some lithium batteries.

Therefore, lithium ion trolling motor battery and lead-acid trolling motor battery have different advantages and are suitable for different application scenarios. Choose the right battery according to your boat project to ensure long-term working ability.
