How long will a 100Ah lithium battery run a trolling motor?
The run time of your trolling motor depends on the amp hour (Ah) capacity of your battery and the motor's current draw. Follow this simple formula:
Run Time (hours) = Battery Capacity (Ah) / Motor Current Draw (A)
For example:
Your trolling motor draws 54A at full throttle. You have a 100Ah battery.
Run Time = Battery Capacity / Current Draw
= 100Ah / 54A
= 1.85 hours
= 1 hour and 51 minutes
So the 100Ah battery would run the 54A motor for about 1 hour 51 minutes at full speed.
To find low speed run time:
If the motor draws 10A at half throttle.
Run Time = Battery Capacity / Current Draw
= 100Ah / 10A
= 10 hours
Can I use LiTime 12V 100Ah TM LiFePO4 lithium batteries as starting batteries?
No. LiTime LiFePO4 lithium batteries arenotintended to be used as starting batteries but deep cycle energy storage, please donot use them to start any devices.
Can I charge LiTime 12V 100Ah TM LiFePO4 lithium batteries in cold weather (under freezing temperatures)?
LiTime 12V 100Ah TM LiFePO4 batteries can charge between 32°F to 113°F (0°C to 45°C). The 12V 100Ah TM version has low-temperature charging protection function, it would cut off charging when it's below 0℃.
What is a group 31 battery?
The group 31 batteries is the most popular battery size, measuring approximately L13*W6.8*H9.44 inch, which is widely used in boats, RVs, home storage, and off-grid. LiTime 12V 100Ah TM LiFePO4 battery measuresL13*W6.77*H8.43 inch ans is 2~3X lighter and 5X lifespan of traditional group 31 batteries. It is a powerful and compact replacement for group 31 batteries.
LiTime 12V 100Ah TM LiFePO4 LiFePO4 battery weighing 23.4 lbs, is 1/3 the weight of a traditional group 31 agm battery or group 31 lead acid battery and releases larger energy. It's a perfect replacement to AGM group 31.
Do you have battery box for group 31?
Yes, LiTime has a portable battery box for group 31. Built in voltmeter, it can be used for marine & RV, fitting for group size 24 battery, group 27 battery size and group 31 battery size.
How to charge LiTime 12V 100Ah TM lithium batteries?
1. Using Solar Panels
The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 300W solar panels. It may take more than one day to fully charge the battery by ≥300W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.
If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
Can I connect the batteries more than 4 in parallel?
During use, inconsistencies between cells can increase over time. When connecting too many batteries in parallel, this can cause faster degrading batteries to trigger protection and fail prematurely. Therefore, paralleling more batteries is not always better. The industry standard maximum is 4 paralleled batteries.
Looks great, will to try this summer. My cottage neighbour's has 2 of them and loves them.

So far so good
The weather has prevented me from putting them to use. I’m giving it a 5 for now. That’s based on the build quality, price, shipping time and tested capacity. I ran capacity tests on both batteries and got roughly 100ah from each of them.
Only time will tell if they can really perform.

Light and powerful
Went sturgeon fishing in the mighty Fraser River and my 100 hour trolling motor li time battery trolled the river in huge current and was almost as fast with my 55 Newport as my 4 horse Honda .
What a combo !

Excellent Customer Service!
Very fast response to my order. Was delivered to my door within a week. After the package was delivered, I found a discount code and they refunded me the full amount that the order would have been reduced by if I had entered the code at the time of ordering. Mavis was very helpful and took care of the refund within hours. Haven't even used the battery yet but very impressed by the customer focus.

Omg awesome!
Things are looking great so far. With all the great reviews on the web. I’m feeling pretty good about the two 200 AH batteries I bought. Thank you for a great product
Allan
Fairly light weight at 80 lbs. Only took about a day to fully charge with solar panels, and it runs my 3000 W inverter with no issues. 400ah is well worth getting instead of 4-100ah batteries connected together due to less wiring and possible loose connections. Highly recommend.
Donald L Anderson
Installed 2 100ah batteries in boat as my house bank with the Litime DC to DC 40amp charger to protect alternator. I have to say very happy with everything.
