The Best Fish Finder Batteries for Kayaks and Smaller Boats

Fish finder batteries for kayaks and smaller boats must be lightweight and compact but accept charge quickly from various sources and should be able to power the fish finder during the entire fishing session without the need to be recharged before going to shore or starting the main engine (if present).

Fish finder batteries are spill-proof AGM and Gel-Cell lead-acid batteries and Lithium Iron Phosphate (LiFePO4) batteries. Most fish finder batteries feature a nominal capacity in the 5 - 20 Ah range.

What is a deep cycle battery plus answers to your boat battery questions

As long as it looks like it’s doing its job, you probably don’t care much about your boat battery. In fact, many boat owners just use the original batteries that came along with their boat.

But what if your battery needs to be replaced? Or, what if you were buying your first boat? Do You Need Deep Cycle Marine Batteries? (yes!) Or would a starter battery do the trick? (Too!) Time to get to the boat batteries…and we’re here to help.

As technology advances, more and better batteries become available. But like a 10-page menu, more options make things more confusing. Might be more difficult to choose!

Marine batteries come in a variety of chemistry, sizes and uses. Before making a decision, it’s better to know what is a deep cycle marine battery, how does it works, and which is best.

First of all, we provide a short, less technical explanation of the most common terms on the boat battery:   

Boat Battery Terms

Think of this basic term as “appetizer”. Familiarity with the battery vocabulary will help you to figure out the confusing specifications and jargon you may come across while shopping.

Amp Hour (AH)

This refers to the amount of energy your boat’s batteries can store. The larger the AH number, the larger the capacity.

Cycle

One cycle is a full discharge and a full charge. Deep cycle batteries usually have a cycle life or cycle rating. This rating indicates the number of cycles you can discharge and recharge the battery before it reaches 80% of its original capacity. At that point, most batteries will need to be replaced.

C rate (or Capacity Hour Rate)

It is actually a measurement of rate at which the battery be charged or discharged. You can also say it is the ratio between current draw, battery capacity and time. Most deep cycle marine batteries follow a standard 20 hour rate. The number “20” means discharge within 20 hours. For example, a battery with a capacity of 100AH and a rating of C20 can deliver 5 amps for 20 hours before being discharged.

Depth of Discharge (DOD)

This is the amount of your battery’s total capacity that you drain before recharging. For example, if your battery has reached 60% DOD, it means that you have 40% capacity left. A battery with a capacity of 100AH would have 60% DOD if you drained it to 40AH.

This is the total capacity of the battery that drain before recharging. For example, if your battery has reached 60% DOD, it means you have 40% capacity left only. If you drain a 100AH battery down to 40AH, it stands for 60% DOD.

Internal resistance

The term refers to the ability of a battery to resist energy as it is charged and discharged. The lower the internal resistance, the better. Batteries with higher internal resistance don’t charge as efficiently and can get hotter while charging because the energy lost is converted to heat.

State of Charge (SOC)

This is how much capacity your battery could be charged in. For example, a fully charged battery has a state of charge (SOC) of 100%.

What is a Deep Cycle Marine Battery?

Now for the main course: What is a deep cycle marine battery?This type of battery support you to power the trolling motor, radio, GPS, fish finder, and other gadgets on your boat (as well as RV parts, but that’s another topic). It is different from a starter battery or cranking battery, which we will discuss more below.

Deep cycle marine batteries can withstand multiple charges and discharges. That’s why (in most battery types) it has thick and heavy plates. It can survive rigorous charging and hundreds of cycles.

Like the tortoise in the old fable “The Tortoise and the Hare,” you might think of a deep cycle battery as a “slow and steady” power source. Their instantaneous power is limited. That’s why you can’t use them to start your motor. For this, you’ll need a starter/starter battery, which we discuss below.

Accessories for Kayak Fishing

There are various items to consider if you're going kayak fishing. These kayak fishing gear are not only useful, but they can also help you catch more fish. Rod holders, tackle boxes, and other storage solutions for your equipment can be purchased, according to Aaron Petras. A paddle holder is one of the most crucial of these accessories, as it keeps your rod secure and tidy. Rod holders are crucial kayak fishing gear that you should bring with you on your excursion.

Another wonderful tool to consider is a GPS fish finder. It allows you to fish in deeper waters more effectively. It may be effortlessly coupled with your smartphone or tablet thanks to its transducer and wireless functionality. Waterproof fish finders can be utilized from the shore, ice, or even a float tube. Many of these items are inexpensive, making them an excellent addition to any kayak fishing accessories collection. These fish finders are available from a variety of manufacturers.

Rods, floats, rigs, hooks, and lines are some of the most crucial kayak fishing gear. The sort of water you fish in will influence the fishing equipment you require. A kayak designed for a flat, calm lake or ocean should be large enough to comfortably fit all of your gear and accessories. Also, conforming to Aaron Petras, you'll need a kayak anchor for your fishing trip. It's crucial to measure the dimensions of the water where you'll be paddling so you know you'll be able to anchor your boat.

A landing net is another kayak item that you might wish to explore. A landing net, such as the Frabill folding, telescopic net, helps keep fish safe and dry. They're also useful for holding all of the extra gear you'll need for kayak fishing. If you plan on fishing for large fish, you'll need this gear. If you're on a tight budget, however, a more basic kayak with a lower price tag might be the way to go.

If you're new to kayak fishing, a personal flotation device (PFD) or a vest is a must-have. The majority of PFDs are large, unpleasant, and inconvenient. Fortunately, Astral's Ronny Life Jacket PFD is lightweight and comfortable, and it comes with a number of features. It not only shields your skin from the sun, but it also gives an extra layer of defense to your head and neck.

Pedal drives are available on the market if you don't want to deal with batteries. These motors send power to a pair of fins using rotary pedals. This enables you to paddle further without having to use your arms. You can also cast without paddling with pedal drives. This is a great alternative for those who don't have a lot of time to devote to upkeep. While engines are more convenient, paddles and a paddle are still required.

If you have a sit-on-top kayak, you can plug the scupper holes to keep the water out while fishing. You can buy a scupper valve to help you paddle in warmer weather in addition to closing the scupper holes. If you don't want to be splashed, a scupper plug or scupper valve will keep water out of the cockpit and off the deck.

Another important kayak fishing item is a decent yak cooler. A cooler, unlike a regular kayak cooler, will keep your drinks and sandwiches cold while you fish. Choosing the correct kayak cooler is critical for a pleasant journey. Soggy sandwiches and lukewarm drinks will be served in a "traditional" cooler. Choose an Igloo 25 Qt BMX cooler for a more portable cooler. It's not too big and doesn't take up a lot of room.

If you're new to kayak fishing, a seat and rudder are essential pieces of gear. These kayak fishing equipment can keep you safe and have fun on the water. For added comfort, the seat and floor pads are adjustable and padded. Aaron Petras believes that a solid rudder will aid in steering through tight gaps and provide good forward control. If you don't feel like pedaling, there's always the motor option, which is a nice addition.

A motor is also required. A center-mounted electric motor is common in kayaks with motors. While this is the simplest option, it does limit storage capacity. If you're on a tight budget, however, a kayak without a motor is an option. You may even attach a fish finder, a camera, and other fishing gear to the board's edges. You'll be more productive for longer once you've become used to your kayak fishing gadgets.

What Size Battery Do I Need For My Boat?

Just like clothing, boat batteries aren’t “one size fits all”. Of course, “one size” items do exist, but we all know there’s no way they actually fit everyone!

That brings us to our next point– it’s  important to choose your battery size carefully. Why? Because not every boat is the same, and neither are every boater’s needs.The point of boat batteries is to optimize your boat’s performance, keep a trolling motor running smoothly, and power gadgets like your GPS or fish finder. Choose the right size battery for your boat, and you won’t damage your valuable equipment or run out of power.

Battery Size Basics

“What size battery do I need for my boat?” may be one of the first questions you ask when buying your boat or upgrading your existing batteries.

Boat dealers can likely help you with this. They may recommend certain batteries, and even install them for you. But what if you buy a used boat? Or what if you’re looking to add more on-board equipment, and your current batteries just won’t cut it?

Maybe you’ve decided to switch from lead-acid to lithium, and are wondering whether a smaller lithium battery can replace a large lead acid one. (Hint: the answer is yes!)

Whatever the case, here are the questions you’ll need to answer:

What kind of boat do you have? (For example, bass boats require bigger batteries than kayaks).

What types of batteries do you need? (Most bass boats need two types of 12 volt batteries: a starting battery, and a deep cycle battery).

What does the boat manufacturer recommend? 

How much amperage do you need?

Will you need more than one battery in parallel to run your equipment?

If you choose an underpowered or overpowered battery for your boat, you risk damaging your electronic equipment, and even the boat itself. So consider the questions above carefully.

What Size Battery Is Best For My Boat?

Ok, it’s time to get a bit more technical. Let’s dive deeper into some of the questions we mentioned above.

What Types Of Batteries Do You Need?

Your boat will need a cranking or starting battery to start its main engine. You’ll also need a deep cycle battery to power your trolling motor and electronic accessories. Add another deep cycle battery if you have dual engines.

There’s one more type of battery that can do both jobs: the dual purpose battery. But most experts agree this kind of battery doesn’t do either job well. You should only choose dual purpose if your boat doesn’t have enough space for more than one battery.

How Much Amperage Do You Need?

It’s time to crunch the numbers! You might not enjoy mathematical equations, but trust us–you’ll enjoy your fishing trips much more if you calculate the AH (amp hours) you need to operate your vessel.

Batteries have an Ah (amp hours) rating. This relates to the actual battery capacity. For example, a battery rated 100Ah delivers 5 amps for 20 hours, or 100 amps for one hour. But that may not always be true, since you shouldn’t discharge batteries past 50 percent of their capacity 

Carry out an “Energy Audit” and see what battery size will meet the energy demands of all your equipment. Here’s a simplified method:

Use the formula W=AV. (Watts equals amperage multiplied by voltage.) Transpose this formula (divide the wattage by the system voltage) to get the number of amps for a certain device.

Examples: If you use a 6 watt navigation light bulb in a 12 volt system, it will draw 0.5 amps. If you use it for 10 hours in a day, the light bulb will consume 5 Ah (amp hours). Most trolling motors use 5 to 30 amps an hour, depending on their load. So your battery setup needs to offer 30 to 200 amp hours.

Finally, add up the average amps per hour your equipment will use to find out how many amp hours your batteries need to cover.

Common Questions

Here are our battery size recommendations for some of the most common bass boat setups:

What size battery do I need for my boat with a 24 volt trolling motor?

You can use two 12V 100Ah batteries for the trolling motor, and one 12V 125Ah battery for the engine starter and other onboard equipment.

What size battery do I need for my boat with a 36 volt trolling motor?

You’ll need one 36V 50Ah battery for the trolling motor, and one 12V 125Ah battery for your engine starter and other equipment. Or, you can swap the 36V 50Ah battery for three 12V 50Ah batteries in parallel.
