Diypow Best Fishing Kayak Batteries

Using a kayak makes our fishing easier. At the same time, kayaking is really a very fun sport. Even if you don't catch any fish, you can still paddle alone in the quiet water at dawn. It's enough to see the scenery.

Compared to shore fishing, kayak fishing is more convenient. In summer, fish hide in deep water and some are almost difficult to catch from the shore. But with a kayak and fish finder, you can find the structure on the bottom of the lake, making it easier to catch fish. Of course, by paddling directly to a small island or under a bridge pier in the lake, you don't have to worry about grabbing a spot with other people. Since the availability of lithium batteries, kayaking has become easier and more fun.

Using lithium kayak battery to power the motor, you can quickly drive the kayak to areas with dense fish populations. As long as you stay for a few minutes, you're sure to have a great time. But remember to bring GPS our 12v lithium kayak battery pack. Keeps you in touch with your family and lets them know you are safe.

4 Types of Kayak Battery Technology

There’s four different technologies you can choose from. There’s the lead-acid battery, gel batteries, AGM batteries (Absorbed Glass Mat), and lithium batteries. Here’s the pros and cons of each:


These batteries are inexpensive for short periods of time and can be recharged many times. However, they are also easily damaged and must be constantly maintained to avoid problems. It is very important to check and replenish the water level every few weeks or you could damage your battery. In addition, leaks can cause damage to the marine environment and pose many safety issues.


These batteries do not require a lot of maintenance and rarely leak. However, the upfront cost is expensive, and if they do require maintenance overuse is difficult to achieve a balance of internal components. In all likelihood, you will only need to buy a brand new battery. They also require more battery charging because they can only be discharged to 50% , while Li-ion batteries can be put to maximum capacity.


Gel batteries are popular because they don't need to be charged as often and can be stored for long periods of time without losing their life. The downside to them is how expensive they are compared to other batteries that have the same RC and MCA. Charging gel batteries can also be an annoying process. The charge cycle can be very slow and you have to disconnect the battery charger in the field once it is done. Not doing so can cause irreversible damage and require a new battery and a whole lot of money down the drain.


Comparing lithium batteries to other batteries is like comparing an iPhone to a flip phone. Both options will work, but one clearly has better reliability, functionality and design. Lithium batteries save a lot of money over time, they last longer, last up to 10 years, are much lighter, maintenance-free, and non-toxic to the environment. Especially lithium-ion batteries. They are the only lithium deep cycle batteries on the market today that use Bluetooth technology. This eliminates any guesswork or worry. With our lithium batteries (unlike other batteries), you know exactly how much power is left.

Diypow Lithium Kayak Batteries


⭐Consistent Output

Most batteries on the market don't output as much current once they reach 50% of their battery life. This means that while you may have 50% of the battery remaining, the current is not very strong, so some of your accessories may stop working. In contrast, marine lithium batteries continue to output the same amount of current even when the battery life is below 50%. Not only that, but LiPo batteries can be completely depleted before they need to be recharged.

⭐Long Lasting

With ion lithium marine batteries, you need to pay more up front, but in the long run, these costs will save you a lot. Compared to lead-acid batteries, lithium marine batteries typically last 2 to 4 times longer (up to 10 times longer). Lead-acid batteries can usually be recharged 300 to 400 times. If you use it every day, this means it will last about a year. By comparison, our Diypow deep cycle lithium marine batteries are rated for 5000 cycles, which means they can be recharged 5000 times. If you use it every day, that's nearly 14 years of use. So while lithium marine batteries are initially more expensive, you're actually going to spend a lot less in the long run.

⭐1/3 Lighter Than Lead Acid Battery

For fishing boats, lightweight lithium batteries travel 1/4 mile more than boats using lead-acid batteries. In general, reducing the weight of the boat makes fishing easier. Diypow deep cycle lithium marine batteries are light weight, compact, fit in almost any boat, and won't weigh your boat down. You'll spend less money on gas and be able to drive better.

⭐6 Strong Protections

Our lithium batteries have a built-in BMS (Battery Management System) that provides protection against overcharge, overdischarge, low voltage, high voltage, short circuit and over temperature.

⭐Fast Charge

Our lithium battery provide 0.25C charge for standard and even 0.5C charge for customization. Lithium battery can be fully charged within 4 hours.

⭐Higher Discharge Rate

Our lithium batteries can provide a discharge rate of 1C, which is 5 times higher than lead-acid batteries. The higher discharge current can easily drive your device.

Kayak Fish Finder Battery Buying Guide

Want to upgrade your kayak now? Add a trolling motor and kayak trolling motor batteries. With kayak batteries, you can cover more water and catch more fish. A deep-cycle 12V marine battery will do the job.

But kayak trolling motor batteries can also power many useful electronic devices. Think fish finders, lights, GPS systems, and mobile phone chargers. Installing the right kayak trolling motor battery can help you enhance your kayaking and fishing adventures.

The best kayak battery is one that is large enough to power your motor and electronics, but small enough to keep your kayak light. So what is it? Lithium-ion batteries. Come and join us for a guide to buying kayak batteries.

1. What are Kayak batteries?

The kayak control motor is a lightweight, self-contained device that includes an electric motor, propeller and steering control. You mount the motor in the bow or stern of your kayak, connect it to the battery, and you instantly have a power boat. Hand- and foot-controlled models are available. Kayak fishing motors usually use a standard 12V marine battery. These small motors are easy to control, easy to install, and you won't break the bank for an upgrade.

2. What Is the Best Kayak Trolling Motor Battery? (Battery for Fish Finder Kayak)

When you compare lithium-ion batteries to lead-acid batteries, the answer is obvious: lithium-ion batteries are the best choice for kayak trolling motor batteries.

They last longer, weigh less, are safer for the environment, and are more efficient than lead-acid batteries. If you want to get your money's worth and want to keep your kayak trips worry-free, you'll want to choose a lithium-ion battery for your trolling motor.

We recommend our Diypow 12V 50AH kit. It has everything you need to power your trolling motor for a decade or more. Also, for long days out on the water, you can check out our 100Ah kayak kit to get you started.

3. How long will a 50Ah battery last on a trolling motor?

Typically a 50A battery can be deep cycled for 3000-5000 cycles. Capable of charging most of the accessories on your boat. Usually a day is no problem.

4. How long will the kayak battery last?

As we said, LiPo batteries are the best kayak batteries. Also known as the LiFePO4 kayak battery. reports show that the Diypow 100A battery can give an angler over 14 miles of travel.

5. Do you need a battery box for kayak?

A battery box for a kayak is not necessarily required, but it is strongly recommended for safety and convenience. A battery box helps protect the battery from water, impacts, and other hazards. It also keeps the battery securely in place, preventing it from shifting during movement. Additionally, a battery box can make it easier to connect and disconnect the battery when needed.

6. What kind of battery can I use to power the fish finder on my kayak?

If you are in a canoe or have a portable fish finder, it is still battery-powered. Typically, fish finders will use either a 12V lead acid or lithium battery. For many years, lead acid has been the standard battery, but more and more fish finders are using lithium batteries.

7. Should a fish finder be wired directly to the battery?

Connect the fish finder directly to the battery (starter battery or auxiliary battery). Do not take shortcuts and run the fishfinder power cord to a block or switch panel

8. How do I choose battery size?

Before shopping for batteries, you want to determine how much power you need. Desired energy storage capacity - - is usually measured using kilowatt-hours per day. Based on the power and runtime of all potential loads supported by the system, a minimum kWh per day value can be calculated.

9. When should I charge my fish finder battery?

12.0 volts or below - At 12.0 volts, your battery is considered fully discharged or "flat" and should be charged as soon as possible. If kept in this voltage range for an extended period of time, the life of the battery will be severely affected.

10. How to maintain a Kayak Battery?

To maintain the performance of your kayak battery, it is vital to recharge your kayak battery when the drip charge drops to 10-25%. Storage in a favorable environment is always a reliable option for battery maintenance. The premise is never to try to overcharge a battery.

What Our Customer Say

Based on 29 reviews
NIce battery

More practical than a AGM lead battery for me. Much lighter (30 lbs). Can be discharged 100 % , compared to 50% on an Lead acid - so really equivalent to 200Amp-Hr (and then only 1/4 weight!).

Good battery for now

The vendor delivered the product sooner than expected and in great condition. Will use the battery to power a 12V 55Ibs trolling motor. So far, I am very happy with the product.

Double the power. Half the weight...!

EDIT: Tonight I cooked my dinner and used the oven for an hour and twenty minutes while I was watching TV with my mini PC on for streaming. This battery had more than enough juice to do all that with power left to spare.

I also have a 55 Quart 12V dual zone refrigerator and freezer connected and it runs 24 Hours a day.

This battery is incredibly powerful. It doubled my capacity and is half the weight. I also purchased the Diypow charger and am able to top it off in a very short time. I mainly purchased the setup for cooking while I'm on the road and I can use my 3-In-1 Galanz for about 40 minutes or so before I have to give it a little juice. My old setup used 4, 100 deep cycle batteries and didn't hold a candle to this Lifpo4 setup. I can definitely see myself getting a couple of these for our off-grid camp next spring. If you're in doubt, take the risk and go for it. You won't be disappointed. Almost forgot to mention that their customer service is outstanding. I did have several questions before I placed my order and they responded very quickly. I've been using this for about a month. Simply Great!

Only use these batteries if you know what your doing!

The Battery is rated at 50AH and on first discharge pulled 51AH down to 10.6 volts. Your getting the full rated capacity.
Its very light compared to the 45AH Lead Acid battery it is replacing.
No fumes or acid to deal with since this battery is inside the vehicle with people(trunk fender well to be exact)
LiFePo4 chemistry is a direct 12v Pb replacement.

Good price

Battery arrived early and after testing it and hooking it up, everything looks good. The seller emailed me after delivery to see if I had any concerns which was nice.

satisfactory for dry camping

Used with another same battery in a camper to get more days of service.

For my trolling motor on the beach

More power , light weight , charge lasts so much longer on my trolling Motor its amazing !!

Quality product and good customer service

I installed this in my 19ft RV connected to a 200w solar system and a 2000w invertor. So far works great, we're able to run the coffee maker, toaster and the 900w microwave in the morning. I may upgrade to 400w of solar to help speed up charging but so far it seems to be holding out really well. I've ordered a battery monitor to help manage the available power.

Excellent battery

I previously had a pouch cell 48v battery pack that lasted for about 1 year before it started holding less and less of a charge and started swelling. This battery has been excellent and seems to drain much slower that the pouch type battery packs. DIYPOW has excellent communication and shipping speed. The battery seems to be well made and came in well-cushioned packaging. I am using it on a 48v 1500w atv and it has no problem handling extended periods of max throttle. 5 star battery and company. Great battery and BMS for electric vehicles and I highly recommend it.

These batteries are exellent

These batteries are excellent so for. I purchased (4) 300Amp hour batteries.
They are 1/3 the weight of my old lead acid battues witch only lasts about 6 years.
I have them installed in series with a Schneider electric 4KW inverter:
They are also connected to a 15KW off-grid Generator (Generac).
If it has raining for days like it has been in Southern California, the 15KW off-grid Generator (Generac)
auto turns on to power up the potteries when they are lower than 50% capacity., So we are never with out power.
They batteries charge up many times quicker than my old lead acid batteries.
We have plenty off power with out 12 350 Watt solar panels.

very good battery, sooo happy convenient shipping, excellent product!

Works great for my diy solar system

Lithium battery for kayak trolling motor

Just because its an off brand, dont let it fool you. I use two of these to make 24v for my trolling motor for my kayak. Its an NK-180 motor. I run 14+ miles at 84% throttle! I had no issues, going on over a year now of frequent use. For trolling motors they work great. Im using a Noco two bank charger to charge them on the Lithium charger setting.

4 Pcs CATL 302AH Deep Cycle LiFePO4 Battery Cells
Karl Jensen
They look good and tested good.

The battery arrived intact and was one of the best matches of the 16 sets I encountered; voltage (0.003V Delta) and internal resistance (0.22 ohms - identical), most of the sides are flat with no swelling, and most importantly the soldered terminals have studs so you don't have to use tools to install the studs yourself. The bus bars are plated real copper, but I use 2/0 jumper diagonals to avoid straining the terminals. I will be doing a capacity test after the top is balanced and my expectations are very positive. nicole answered my questions and was very prompt in keeping in touch.

Update 4/19/23.
I did a quasi-capacity test and they far exceeded expectations. Conditions: 630 lbs compressed, top balanced. Running/starting at 56 volts (3.5 volts per section) and ending at 48 volts (3 volts per section). Loads ranged from 60 to 30 amps (normal house load) with two different meters showing results of 305 and 298 amp hours. Yes, there is more room at the top and bottom of the charge, which would allow for more capacity. Deltas are less than 0.008 at the flat of the curve during charging (60 amps) and discharging. less than 0.060v Delta at both ends. the balancer only starts working when each cell exceeds 3.4 volts. Float at 3.4 volts. Absorption/end charge 56.2 (3.512 volts per cell).

Great Quality

Put these in the RV. They have worked very well and we are happy to move away from our wet / lead acid batteries. Really liked the sturdy side post connectors for the wires hooking up to the batteries. Very sturdy.

I recommend 100%

I love this battery so far. I have it connected to a 36v minnkota trolling motor and I can have it on for 9-10 hours so far. Customer service is also A++

These are incredible batteries.

I have lived off grid solar for 33 years and these batteries (I have three) are great. With the help of a Diypow inverter I can now use a dishwasher, microwave, clothes washer and dryer and large tv all powered by the Sun. These batteries offer the greatest bang for the buck.

Arrived promptly

Arrived promptly & in excellent condition. Thanks!!!

Great LFP battery

I didn't rip it apart to check the BMS, but I've run it through a number of charge/discharge cycles now and it's been a champ. So far, so good. What is there to say? It acts like a 48V LFP battery pack.

One thing I will note, and this applies to all LiFePO4 (LFP) batteries, is that the BMS should always be viewed as a final fail-safe and not generally be relied on for over-volt and under-volt protection, because such protections may cause it to trip while current is flowing and that is never good for these FET power switches. It is always better to program your charge controllers with slightly lower voltage limits and always better to program other logic to shut equipment down when the battery is exhausted first, then "pull the plug" with a battery protect device, and make the breakers trip at slightly lower amperages, and not rely on the BMS in the battery itself pulling the plug for you. If you want your batteries to last, that is.

I will update the review after a few months of operation.

4 Pcs CATL 302AH Deep Cycle LiFePO4 Battery Cells
Very well matched set

The four cells are perfectly matched in voltage (<5mV variance). The vendor was very communicative during the international shipping crisis and got us the batteries as fast as was possible under the circumstances. Interesting that they fit perfectly in an Airstream Basecamp battery box with room for a BMS.

Very compact

Bought this to replace the same capacity AGM in my van conversion. Very compact and light weight compared to my 80lb AGM. Superior packaging and clearly written instructions. Arrived double boxed. Very impressed with the quality. Contacted the seller about charging and got an immediate response. Only time will tell if there is going to be an issue with the bms. Set my mppt solar controller to lithium and seems to be going the job charging to spec. Cant beat the price really, I paid almost this much for my AGM battery.

I'm loving the product

Although it took awhile for the battery to get to me I am very impressed with it. I put installed it into my 36 volt EZGO golf cart and it's terrific. Top speed hasn't changed much but acceleration has and I'm very surprised that I have played 36 holes and the volt meter has barely moved from from full without recharging. So far I would highly recommend it for a golf cart.

Trailer life

Excellent battery so far very happy survive the whole winter. Everything still working good first battery Ive had that actually last excellent battery perfect.

4 Pcs CATL 302AH Deep Cycle LiFePO4 Battery Cells
Don Owen
Good Cells

Ordered the 8 counts 310AH cells to set up a 24-volt system to a cargo trailer conversion. The shipping was very fast for me. Did a capacity test and got the full 310AH. After a couple of days of testing, I had a cell go bad. Howard help me troubleshoot the cell and we figure the cell did go bad. They then made things right without question and replace the cell at no cost to me. plan to order more in the future.

Does as advertised

I thought the BmS was faulty because it only charged to 52 volts. I decided to to test it anyway , so I charged it up to 52 volts let it sit overnight and tested it at its resting voltage of 49.8 volts this morning, I was so surprised to see the results, it stayed steady between 49 and 50 volt for hours as I was averaging around 6amps then it stayed between 48 and 49 volts for hours. I pulled 4KWH and it was still at 48.3 volts. Its a great battery , its well built has good dual positive and negative connections.

Perfect replacement for lead acid

Replaced two 58 Ah lead acid batteries with this 200Ah Diypow battery. I dont even plug trailer in anymore when Im home, its been 8 days now running 12 volt fridge and battery is still at 84%. Trailer has 1 -195 watt solar panel attached to roof and I have a 150 watt panel on a stand that I used to set up to help charge batteries, but I havent needed to use it with the new battery. So far I love this battery and May pick up a second one.
