Reliable Power for Trolling Motor/Back-Up Power/Solar Power
3 Ways to Charge The Lithium Trolling Motor Battery
LiFePO4 batteries offer versatile charging options, allowing you to keep them powered efficiently no matter your environment. Here are three reliable ways to charge your battery:
LiFePO4 Charger (AC-DC)
For a fast and efficient charge, use a 43.8V 25A AC-DC charger. In just 2 hours, your battery will be fully recharged, ensuring minimal downtime and maximum performance. This is the go-to method for quick, convenient charging at home or in any location with AC power access.
Solar Panel + MPPT Controller
For eco-friendly charging, harness the power of the sun. With a solar panel setup of at least 600W, paired with an MPPT (Maximum Power Point Tracking) controller, you can charge your LiFePO4 battery in just one sunny day. This method is ideal for off-grid applications or environmentally conscious users looking for renewable energy solutions.
Generator + AC-DC Charger
When access to solar power or grid electricity is limited, a generator can be an excellent alternative. Using a 43.8V 25A AC-DC charger connected to a generator, you can fully recharge the battery in just 2 hours. This option is perfect for remote locations or as a backup charging solution during emergencies.

What is the ideal thrust range for a 36V 50Ah trolling motor battery?
100-120 lbs trolling motor
What should I do when I receive the battery?
Upon receiving your battery, please be aware that it may have a low State of Charge (SOC) due to transportation and storage. To ensure optimal performance, we recommend charging the battery immediately to prevent over-discharge.
For Bluetooth batteries, they may arrive in an off state, showing a virtual voltage of 3V to 5V at the terminals. This is normal and can be rectified by using an AC-DC LiFePO4 lithium battery charger or an MPPT solar charge controller to charge the battery for 3 to 10 seconds, which will activate it for normal use.
If you intend to store the battery for an extended period without use, charge it to a SOC between 30% and 50% and perform maintenance every three months. This practice will help maintain its functionality and performance over time.
Can I use the trolling motor battery in my electric outboard motor?
Normally, it's not recommended to use a battery designed for a trolling motor in an electric outboard motor since the surge discharge current might not be sufficient. Outboard motors often require higher power for acceleration and sustained operation, which can lead to higher surge currents that trolling motor batteries may not handle well.
If you’re planning to use an electric outboard motor, it’s best to invest in a battery specifically designed for such applications like LiTime Outboard Motor Batteries. These batteries are built to handle the high power requirements and ensure optimal performance and safety.
Read on Electric Outboad Motor VS Trolling Motor for more detailed information.
Can I connect the battery in series or parallel?
LiTime 36V 50Ah lithium battery supports connecting up to 4 identical batteries in parallel for up to 36V(38.4V)200Ah battery system. However, the battery do not support connect in series.
To connect in series or parallel, batteries should meet the below conditions:
- identical batteries with the same battery capacity (Ah) and BMS (A);
- from the same brand (as lithium battery from different brands has their special BMS);
- purchased in near time (within one month).
Can I charge LiTime 36V 50Ah TM LiFePO4 lithium batteries in cold weather (under freezing temperatures)?
LiTime 36V 50Ah TM LiFePO4 batteries can charge between 0℃ to 50℃ / 32℉ to 122℉. The 36V 55Ah TM version has low-temperature charging protection function, it would cut off charging when it's below 0℃. It's recommended to charge the battery indoor during cold days.
Do you provide marine staring batteries?
Yes. Visit LiTime Marine Starting Batteries to choose the right one.
How do I monitor the battery status?
The battery is equipped with an integrated Bluetooth module, enables convenient monitoring of the battery status using your smartphone through the LiTime App.

Quick delivery on both of the batteries I bought. And have been working awesome so far for me. I recommend them.

Runs great and weighs only 33 lbs compared to a std 12v starter battery which is 43 lbs. I ran my Garmin Force Kraken trolling motor for hours around the bay without any issues. I did have a minor issue with the app, though, and Customer Service was quick to respond and it was fixed within 24 hours.

I own a Champion 206, 250 Yamaha with Lowrance Ghost trolling motor, not a lightweight rig. I fish a few local lakes that are electric motor only. I have went out three times in the last two weeks on one of the local lakes and when I've returned to dock after 7 or 8 hours of hard fishing I've had 57%, 48% and 41% battery left. This battery has a ton of power and is proving to be much more efficient than my old lithium batteries that were 3x 12v 100Ah. Very pleased with the performance of this battery and only having to deal with one BMS and a much smaller footprint in the rear of my boat.

Installed a pair of these in my 22 foot SeaArk BXT 220 for my Power Pole trolling motor. Ran it for 4+ hours between level 5 and 15. It only used 2% of charge!
C
I have had a chance to use it three times on my 36V 105# Motorguide digital tour pro trolling motor pulling around a 20' Skeeter Bay boat. I charged to 100% upon receiving the battery and again after the first use (as instructed). I used 9% after use #1 and 11% after trip two and three. The 36v 50 amp battery replaced (3) orbit 12v AGM batteries. I wasn't sure if I would need the 100 amp battery but I settle for the 36v 50 amp and I am glad I did. 12 hours of normal fishing (bass) and only 11% usage. I did some research and the recommendations I found suggested that normal usage should be between 30% and 80%, that it isn't necessary to charge to 100% unless you plan on heavy usage over a couple of days. I have been fishing for 50 years and gone through more lead acid and AGM batteries than I can remember. The upgrade to lithium is a no brainer and the LiTime battery exceeds my expectations. It charges from 80 to 100% in less than an hour with the 25v LiTime charger. My next upgrade will be for my Lance truck camper and I will be buying LiTime batteries for that. Oh buy the way get the bluetooth option.
R
So far I am very impressed and happy with LiTimes 36V smart 50 AH battery. I love how I can see the State of Charge. I bought two to have 100 AH with a battery selector switch, but I have only used 32% of one battery on (2) 6 hour jetty trips where I would spot lock the majority of the time. Great job LiTime!
R
Loving these batteries. I got 2 in parallel for my Lowrance ghost. Ran on power 4 for 2 hours and only used 3%. Highly recommended
T
I’ve only used the battery once but I was impressed by how little it discharged in a full day of fishing. I really enjoyed being able to monitor the charging and discharging rates with the Bluetooth app.
