What are the best batteries for Trolling motors?

When it comes to trolling motors and their batteries, kayakers and swimmers have a varied preference about what kind of battery they want. Well, for beginners, when selecting the batteries for trolling motors, you need to keep in mind your fishing frequency, budget, and of course, the dimensions of your kayak or boat. After that, there is quite a section of batteries that are best for your needs and conditions. Here we have rounded up a couple of points you should view before purchasing the battery for your trolling motor.


Since 12 Volts is the battery range you will mostly encounter around you, it will only power the appliances and trolling motors with identical voltage. But for higher kayaks, you might require a voltage range of 24 Volts, which means you have to select a couple of batteries to fulfill your power requirements. Most kayaks and canoes only require 12 Volts trolling motor, so the point is moot as most trolling batteries would be served with only a single battery and will pair well with your kayak.


As we all are familiar with durable batteries lasting longer, you should always select the batteries with as many characteristics as possible to accentuate the battery’s durability. For instance, some batteries arrive completely sealed in their encasing, such as AGM batteries. Being sealed in their encasing enables them to avoid any susceptibility of leaks, damages or any issues that might have arisen in case of a shock or vibration.

However, unlike Voltaic cell counterparts, AGM batteries are more expensive. Their durability plays a vital role in their cost. An expensive battery might be difficult to swallow in the start, but if you think it through in the long terms, such batteries keep paying up year after year of usage down the road making it worth your extra bucks.


Wet cell batteries need to be maintained from time to time. Such maintenance includes refilling the batteries with filtered water and being aware of any indication of further cleaning or corrosion.  It might be easy to prevent corrosion by using the right blend of bicarbonate of soda and water. But most kayakers inform that the hassle of the maintenance is not worth the battery. On the other hand, Voltaic cell batteries are much more affordable.

If you want to save a couple of bucks of your savings, the need for minor maintenance and its hassle could be worth it.  There is no maintenance required in lithium-ion and AGM batteries.  The least of your worries is checking the battery’s water levels and interior for any sign of damage. Even though AGM and lithium-ion batteries are much most expensive, they are 100% maintenance-free.


Both the load and the dimensions of a trolling battery affect the whole performance of the battery. Therefore, you need to keep in mind that the battery is not too heavy for your kayak. The battery would drain significantly more quickly after reaching the weight capacity of your kayak. You need to select a much lighter battery if you reach the right capacity. In some cases, where the kayakers barely have any weight on board, a heavier battery than required is not usually an issue.

Thirty pounds’ battery is normally suitable for a kayak traveler, and the batteries typically weigh around 25 to 30 pounds. You shouldn’t carry a bulky battery if you are using a smaller kayak or boat because then the weight would negatively affect the battery’s efficiency.  On the other hand, a heavier battery would be more accurate for an enhanced performance if your kayak or boat is bigger than normal kayaks.

You would even prefer a much lighter and compact battery option if you have to remove and then transport your battery from your kayak after every journey or use. Again the point would be moot if you don’t have to carry the battery around after every use since it would be permanently installed and the load would be a non-factor.


The lifespan of the batteries varies greatly from one trolling motor battery to another. Voltaic Cell battery lasts the shortest with a lifespan of usually two years with optimal maintenance. In contrast to that, AGM batteries are more durable, with an extended lifespan that reaches up to five to six years. Moreover, the new lithium-ion battery counterparts are the cherry on top of the cake by having a life span of almost a decade. You should bear in mind that an extended lifespan arrives at a steeper price.


You should always consider the size of the battery before purchasing it in haste to check if it is compatible with your kayak or boat. If your kayak is not sparing any posh of space, it might be wise to select a trolling motor battery that is compact and can easily fit on board. However, if your vessel is huge with lots of extra space, then a much bigger battery would be perfect.

A massive kayak would result in more power being consumed per hour. Therefore you would need to select a bigger battery for a heavier vessel or kayak. A bigger battery also guarantees a better chance of powering the trolling motor of your kayak for an extended period consistently.  Hence, you can enjoy your leisure time without any fear of the battery finishing after an hour or two of consumption.


You should also consider the frequency required to charge your battery. If your usual leisure adventures involve the consumption of your trolling motor very often, then it would be necessary that your battery has the feature of fast-charging since it would be needed in further adventures and would also lower your waiting time. With these features in mind, AGM batteries are your ideal bet. The AGM batteries add a layer of convenience as they charge up to 90% in just under an hour.
