I installed this 12V 100Ah LiFePO4 battery in a protective battery box for my fishing setup, and the installation was straightforward. The terminals are clearly marked and large enough to make a secure connection, while the compact case fits neatly inside the box without taking up unnecessary space. I also like that the included carry strap makes it much easier to move than the heavy lead-acid battery I used before.

After several fishing trips, the battery has provided steady power to my trolling motor without noticeable voltage drop during normal use. I usually run the motor at low to medium speed for positioning and moving between fishing spots, and there is still plenty of capacity remaining at the end of the day. The 150A BMS also gives me more confidence when the motor briefly draws higher current during startup or when pushing through wind and current.

The Bluetooth app is one of the most useful features. I can check the remaining SOC, voltage, current and temperature directly from my phone instead of guessing from a basic battery indicator. The connection has been stable when I am near the boat, and it makes it much easier to decide whether the battery needs charging before the next trip.

Overall, this has been a practical upgrade for my trolling motor system. It is lighter, easier to monitor and holds its voltage better than my previous lead-acid setup. The battery box and wiring in the photo are my own installation, but the battery fit well and connected without any special modifications. So far, I am very satisfied with its performance and would recommend it for a small fishing boat or similar 12V marine setup.

The battery arrived in good condition and feels very solid, especially compared with the lead-acid battery I was using before. I tested it on the workbench before installing it in my fishing boat, and the voltage and Bluetooth connection worked as expected. The terminals are sturdy, the carry strap makes it easier to move, and the compact size fits my setup well. So far, it has been a straightforward and worthwhile upgrade for my trolling motor.

I’ve been using this 12V 100Ah battery for my trolling motor, and so far it has performed very well. It delivers stable power throughout the trip and has more than enough capacity for a full day of fishing at moderate speeds. The Bluetooth app is also useful for checking the remaining charge without disconnecting anything. Despite being much lighter than my old lead-acid battery, it feels solid and is much easier to carry down to the water. A good upgrade for a small fishing boat or other outdoor 12V equipment.

I usually fish for four to six hours at a time, mostly using the trolling motor at lower speeds. This battery gives me enough runtime for my normal trips. The app is useful for checking capacity during the day, so I no longer rely on a basic voltage gauge.

I posted a review after one month. Now at three months and about 15 fishing trips. Here's the update: battery still shows 100% health in the app. The cells are still balanced (checked individual voltages, all within 0.02V). I've been charging after every trip with the LiThink 20A charger. No swelling, no performance drop, no connection issues. The Bluetooth still connects instantly. Very happy I made the switch. Will report back at 6 months.

Got this TM series to replace my dying AGM on a Minn Kota 70lb thrust. The weight difference is shocking—picked it up with one finger. Fished a tournament last weekend, 9 hours on the water running spot lock in wind, still had 58% left at weigh-in. Bluetooth app shows real-time draw, I was pulling 25-30A at full speed and battery didn't even get warm. My buddy already ordered one after seeing mine. LiThink is doing something right.

I replaced the lead-acid trolling motor battery on my boat with this one, also 100Ah, and it’s nearly 30 pounds lighter. The most noticeable difference is that moving it around no longer strains my back, and the stern sits a bit higher in the water. I fished for 7 hours over the weekend, and when I got home, the Bluetooth app still showed 67% battery remaining. My old lead-acid battery would have been done long before that.

Used it all day with my trolling motor and still had plenty of power left. Big upgrade from lead acid.

From about 45% remaining, my 20A lithium charger usually finishes in roughly three hours. I plug it in after cleaning the boat, and it is ready well before the next morning. The charging time has been consistent from trip to trip.

My boat has a basic electrical setup, so I did not need every feature this battery offers. I wanted reliable power, lighter weight, and enough capacity for a normal fishing day. It has delivered exactly that without making the system more complicated.

Removing the old lead-acid battery took more effort than installing this one. The weight difference is significant, especially when leaning over the side of the boat into a tight compartment. That alone made the upgrade worthwhile for me.

I used the battery during a full day of bass fishing with frequent spot changes. The trolling motor ran in short bursts throughout the morning and much more continuously after the wind picked up. I finished the day with around 35% remaining and no noticeable reduction in thrust.

One cold morning, charging did not begin immediately because the battery temperature was below the safe range. The heating function came on first, then charging started once the cells warmed up. It took longer than normal, but the protection worked exactly as intended.

I stored the battery for several weeks between trips and expected to recharge it before using the boat again. The charge level had barely changed, so I was able to launch without waiting for the charger.

The app showed that the highest motor setting was using much more current than I realized. I now cruise one level lower whenever possible, and the difference in speed is small while the runtime is noticeably better. That information has actually changed how I operate the boat.

On my boat, the trolling motor is also used for slow maneuvering around docks and shallow coves. The battery responds well to frequent starts, stops, and direction changes. I have not seen any BMS warnings during that kind of use.

I bought this mainly to reduce the number of problems caused by my old flooded battery. No more checking water levels, cleaning corrosion every few weeks, or worrying about acid leaking into the compartment. The new setup is much cleaner.

I had a question about using my existing 14.6V charger, so I sent a message before connecting it. Customer service replied by email with a clear answer and confirmed the settings I needed. Charging has been normal ever since.

The battery arrived in good condition, and the terminal covers were still firmly in place. I installed it the following weekend and found the case and hardware better finished than I expected at this price.

My favorite improvement is not having to remove the battery after every short trip. I often fish for two hours after work, and one charge usually covers several evenings. I just check the app before leaving and recharge when it actually needs it.

After using it for most of the season, the runtime is still predictable. I know roughly how much capacity a calm evening will use and how much extra a windy day takes. There has been no noticeable decline after regular charging.

I fish a narrow river with a fairly strong current. Most of the time I use low speed, but short sections require much more power to move upstream. The battery handles those changes without the motor cutting out or hesitating.

The battery has been through several wet mornings and one day of steady rain. It stays inside a battery box, but spray and damp gear are unavoidable in my boat. Everything has continued working normally, which is why I specifically chose the IP67 trolling-motor version.

I use this on an inflatable fishing boat that has to be carried from the car to the water. Weight matters a lot with this setup, and this battery is manageable for one person. It also leaves more floor space than carrying two smaller batteries.

I like that I can check the remaining charge without opening the rear compartment. The Bluetooth signal reaches the front seat of my boat, even with the battery under a covered hatch. It is much more useful than the simple voltage gauge I relied on before.

We had a strong crosswind during the last trip, so the trolling motor was constantly correcting the boat’s position. The battery worked harder than it normally does, but there were no interruptions or sudden loss of power. I still had enough reserve for the trip back across the lake.

This battery has made my fishing kayak much easier to manage. The old lead-acid battery made the rear sit too low in the water, especially with tackle and a cooler onboard. The lighter lithium setup improved the balance immediately.
