4 Types Of Lithium Trolling Motor 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 Trolling Motor Battery


⭐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.

Best Trolling Motor Battery Buying Guide

Deep cycle trolling motor batteries are specifically designed for boat use. Most batteries will make your boat heavy and difficult to move if maintenance is required. Trolling motor marine batteries are light weight and compact enough to fit in almost any boat and won't weigh your boat down.

When shopping for a lithium battery for your tractor, you need to consider amperage and voltage. The larger the tractor, the more battery capacity you will need.

1. What is a trolling motor battery?

The lithium control motor battery is a lithium iron phosphate (LiFePO4) deep-cycle battery. Its purpose is to provide slow, steady power to control the motor. Most lithium batteries are 12 volts, but 24v battery trolling motor are also available.

2. What kind of battery do I need for a trolling motor?

We recommend selecting a 12-volt deep cycle marine battery with a minimum 110 amp hour voltage rating. Usually group 27 size or larger. The higher the amplifier hour rating, the longer your motor will run.

  • 12-volt battery trolling motor
  • 24-volt trolling motor battery
  • 36-volt lithium trolling motor battery

3. Do you need a special battery for a trolling motor?

A 12v trolling motor battery is a battery designed specifically for boat trolling motors. The purpose behind it is to provide power over a longer period of time when slowly passing through the fishing area. In contrast, a boat starter battery is used to start the ignition.

4. How long will a 100ah lithium battery run a trolling motor?

A single Diypow 12V 100 amp hour (ah) battery will power a full day of run time on a river motor. On lakes or low power settings, some anglers report 2+ days of run time. Easy to use.

5. How long will a 12V marine battery last with a trolling motor?

Typically, a 12-volt marine starter battery will last 5 to 10 years, depending on use. Trolling motor batteries are capable of providing a constant current and fast recharge. Maintenance free.

6. How many amps does a 55lb trolling motor use?

Example: The NV 55lb thrust motor draws 52 amps at full speed and uses one 12V battery.

7. How to charge lithium batteries when you are on the lake?

There are 3 ways to charge your 12V battery, as follows:

Diypow Trolling Motor Battery

8. What size battery do I need for a 44 lb thrust trolling motor?

As a rough guide, smaller motors (18 lbs - 34 lbs) would benefit from about 60AH, while larger motors (44 lbs - 60 lbs) would be matched with a battery of about 100AH or more.

9. How many batteries do I need for a 36 volt trolling motor?

Small and medium jet engines use a 12V trolling motor battery, while larger jet engines use larger 24V and 36V systems, so 2 or 3 trolling motor marine batteries are required.

10. Will a boat motor charge a lithium battery?

Yes, a boat motor is the best option to charge the battery. So, make sure to charge the battery after coming back home. No doubt it is the best habit, so continue it.

11. How often should I charge my trolling motor battery?

It is suggested to charge the trolling battery in the offseason. In these seasons, the power flows through the battery continuously. You may also charge the batteries after each month. Never keep your battery uncharged for a long time. Otherwise, it will reduce performance and lifespan.

12. Should you leave your boat plugged in all the time?

No, you should not keep the charge in the boat for a long time. Otherwise, there will be more chances of corrosion and rate of discharge.

13. Why do you need two batteries for a trolling motor?

When you have two batteries for trolling motors, it means there is more power and energy to run the engine. Therefore, the trolling motors can run continuously.

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.
