A lead-acid wet cell battery 12V lifepo4 battery typically lasts between 2 and 4 years with proper maintenance. AGM and lithium batteries may last longer, with some lithium batteries boasting a lifespan of up to 10 years or more. Whether you’re a seasoned angler or a first-time boat owner, this guide will provide you with all the information you need to select the right trolling motor battery for your needs.

I still use an Everstart Marine battery for my cranking battery because all it does is start the boat and run my livewells. I keep mine in the YakAttack BackPak Pro Krate along with my Livescope module. I can take the whole crate out and charge and travel with ease. Then I can fasten the crate to my Kayak to keep my battery secure on the water. The ZPRO Lithium 12V 50Ah has been a perfect kayak solution for me.

You get the same rated capacity even when discharging them very fast. This would normally compare with a lead-acid battery that is rated at 160Ah. Most lithium batteries can be discharged down to 10-20% SoC (State of Charge). Lithium batteries are lighter, offer better performance, have longer run times, and last much longer than traditional lead-acid batteries.

Each battery type has its own pros and cons, so it is not a one size fits all type of choice. For those on a budget, an AGM battery will prove to be best as it provides power, longevity and functionality at a fraction of the cost of a lithium-ion battery. For those who have a generous budget, a lithium-ion battery will prove to be better due to its extended lifespan, lack of maintenance and fuel saving benefits from a reduce weight load. Again, the price of a trolling battery will depend on its size, model and manufacturer. Cheap marine batteries start from around $50 and can go up to more than $2000 for a high-end model.

The 12.8V 160Ah Impulse Lithium battery will run 5 graphs, plus Humminbird 360 and Active Target 2 modules, all day for several days before needing to charge. It also has plenty of continuous cranking amps to fire a Mercury 250 PRO XS 4-stroke without fail. They charge quickly and hold a charge well with a good lithium charger. With a 12V battery you have 4 cells at roughly 3.2V or something like that to get you to 12.8V. So if one of those cells gets close to its shutoff level, the whole battery is dead.

Since the electrolyte is totally absorbed by the AGM, the VMAX is classified as “non-spillable and non-hazardous”. A tough tank seals and protects the tightly packed plates delivering the VMAX in a 100% maintenance-free package. Though VMAX tanks are best known for their long life span, their capability to recover after repeated deep discharges is what makes them the favorite choice for any application.

So if you find the motor to be very weak after a day’s use or against the current, upgrading the trolling motor battery group 27 to group 31 could be helpful. They’re powerful and reliable, even in very hot or icy environments. Still, if you anticipate using your trolling motor on rough water, a leakproof AGM or lithium-ion battery would be a better choice. This battery is a great trolling motor option if you use a tandem fishing kayak or a small boat.

For example, in kayak fishing, it’s vital to have balance and stability in the boat. With the Dakota weighing a mere 17.6 pounds, with dimensions 9.01×5.43×8.38 inches, this easily fits your kayak. And even with its smaller size, the Dakota still has 54 Amp Hours (run time), allowing for almost the same runtime as the Optima OPT 8016. This battery weighs 68 pounds with dimensions 12.1×6.7×8.2 inches.
