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.
Had the first one for some time. Running livescope. Bought 2 more for trolling motor. Work great. Friend also bought 2 after seeing mine.
Battery and charger was shipped-very fast both products was packaged very good with no damage . I charged the battery every thing worked perfect I really like the Bluetooth app to monator the battery I can’t wait for better weather to try it out !
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.
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.
So far better than expected. Went out three times without recharging.still at 42%. Bluetooth works great and can keep track of how low batteries are getting. Lightweight and cost effective. Looking forward to see how many years I can get out of them.
very happy with new batteries. They work great and I love the blue tooth connection to the app the monitor them
Very happy with my purchased the battery shipped quickly and I was very surprised of how lite weight it is, the app works great for monitoring and use of all the other info too
