Want to know about kayak trolling motor batteries? Then you've come to the right place. There are three main things you need to consider before purchasing a kayak trolling motor battery. Battery type, amp hour ratings and budgets. Our topic this time is mainly about battery types. Lithium-ion batteries are the best lithium trolling motor batteries because they are very small and lightweight, charge quickly and discharge slowly. This is the same type of battery found in your phone or laptop. Here, I would also like to recommend POWERWIN battery, which is definitely the best lithium trolling motor battery.

Popular Science on lithium Trolling Motor Batteries

First, lithium batteries last longer. The cycle number of lithium standard batteries is between 2000 and 5000 times, especially LiFePO4 (lithium iron phosphate) batteries, under certain conditions, such as optimized charge/discharge regime and proper temperature control, they can achieve higher cycles frequency. Traditional lead-acid batteries provide -500 cycles. Lithium batteries have a lifespan of up to 10 years, while lead-acid flooded and AGM batteries have an average lifespan of 2 to 5 years. An extended service life means fewer replacements, ensuring longer investment intervals.


Secondly, lithium batteries tend to have higher energy density and can provide power more stably than similar batteries. Even when discharged to 90%, they retain up to 70% of their capacity. In contrast, a lead-acid battery may only provide 50% of its capacity when it is 50% discharged. This stable power output ensures your trolling motor is operating at peak efficiency, even when the battery power is reduced.


Additionally, size and weight are critical to ship performance. On average, lithium batteries are 40% lighter and 20% more compact than lead-acid batteries. This economy of weight and space not only increases the vessel's flexibility but also frees up space for other important equipment.


Finally, lithium batteries require virtually no maintenance, requiring no regular electrolyte checks or water additions, which are conventionally associated with lead-acid batteries.


But it should be noted that lithium batteries require special chargers to prevent overcharging. So, best lithium trolling motor battery is the battery that people generally buy in the market!

Best lithium trolling motor battery I have ever seen is powerwin battery-BT200. It has a voltage of 12.8V and a current of 200Ah. The BMS system is used to protect the battery, and the chip also adopts A specification. Deep cycle lithium batteries can be used for about 15,000 times until the battery is completely scrapped. It can survive in difficult environments ranging from minus 20 degrees to 50 degrees. It is one of the must-have items for outdoor travelers.
