What are the Differences Between a Group 27 and Group 31 Battery?

The main difference between LiTime Group 27 and Group 31 battery lies in their physical size. Group 27 batteries (12.13*6.69*8.31 in) are generally smaller compared to Group 31 batteries (13*6.77*8.43 inch), which is compatible with Group 27-31 battery boxes.

Trolling Motor Battery

Just installed this battery and the Bluetooth app. So far, super impressed. We spent 5 hours on the lake on decent wind, with the trolling motor holding us in place. After the 5 or so hours, the charge was still at 85%

Installed two 100ah group 27 batteries to savw weight in the front of our 5th wheel

Installed two 100ah group 27 batteries to savw weight in the front of our 5th wheel. The batteries are performing well so far. Customer service from LiTime is off the chart positive. I had an issue with shipping that may have been self induced. The LiTime team had the problem solved in no time and I can't thank them enough.

First off its would like to say is that I haven't been able to use the battery yet

First off its would like to say is that I haven't been able to use the battery yet. But I will touch on some points i know so far. The Bluetooth seems to be working great as it gives you real time info about the battery and keep track of your charging so you dont over charge. I also love the weight of the battery. I have the group 27, as its perfect for my kayak, with this being said, i will update when I have a chance to actually but the battery to a test.

Great Company

Site was easy to navigate, batteries came in less than a week, they run great on my 24v 80lb thrust Minn Kota Terrova. Trolled in the lake on full power and had to turn it down it was too fast. Fished docks in a bay and they lasted all day with lots of life left. I’ll be buying another for my livescope unit.
