I have used this battery for a couple of weeks and I am very pleased with the performance.
I
More power, less space, less weight, unparalleled customer service. The "single" 24v battery lasts longer than my 2 lead acid 12v batteries ever did. Very impressed with this company.
M
After upgrading to the LiTime 24V 100Ah Group 31 Bluetooth Lithium Battery, I can confidently say it has exceeded my expectations. The battery delivers consistent, reliable power throughout long days on the water and has completely eliminated the voltage drop issues I experienced with traditional lead-acid batteries.
One of the standout features is the built-in Bluetooth connectivity. The LiTime app makes it easy to monitor battery percentage, voltage, and overall system status directly from my phone, giving me peace of mind without having to guess how much power remains. The connection is quick and reliable, and the real-time data is extremely useful during extended fishing trips.
The compact Group 31 design is another major advantage. Despite its smaller footprint, it packs an impressive 2560Wh of energy and easily powers my trolling motor all day. The battery is significantly lighter than comparable lead-acid setups, which helps reduce overall boat weight and frees up valuable storage space.
Performance has been excellent in demanding conditions, including windy days that require frequent use of spot-lock and continuous trolling motor operation. Even after a full day on the water, I still had plenty of battery capacity remaining. The low-temperature protection and built-in battery management system add another layer of confidence, especially for anglers who fish year-round.
Overall, the LiTime 24V 100Ah Group 31 Bluetooth Lithium Battery offers exceptional value, long runtime, smart monitoring features, and dependable performance. If you're looking to upgrade your trolling motor battery setup, this is a fantastic investment that delivers both convenience and reliability. Highly recommended.
M
I have been using the battery for about a month now. It powers my 24 volt trolling motor just fine. I like the blue tooth information feedback for the battery. After 7 to 8 hours of fishing using the trolling motor frequently I find at the end of a trip I have roughly 90% of power still remaining. Using a LiTime 2 bank 12 volt 24 volt charger The battery will go to full charge in about 4 hours and the combination has given me more storage room when compared to my old lead acid batteries and a 3 bank charger.
B
Well it’s this simple, 8 hours of wind and spot locking on Toledo bend. If you know this lake it can be brutal, and after that it still has 81% battery storage. What do you think, I think I made the right choice on my 24 volt size 31 battery. Thanks Li Time.

Amazing quality
G
So far so good. Light weight and well made. Love the ability to connect to Bluetooth to check battery status before leaving the house.
A
Amazing the difference from an acid filled battery to the lithium! I would highly recommend, it is well worth the money.
