  • Amazing for 36v Trolling Motors!
This thing is amazing! I replaced 3 Group 31 AGM batteries with this 1 Lithium and it performs even better! I have been out for a full 8 hours of trolling mangrove lines/using spot lock and it didn't even drop 10%! Not to mention the weight savings from going from 3 to 1 battery. It even gave me way more room for storage now. You will need to get a lithium specific charger to go with it, but it's sooo worth it! If you are on the fence, don't think twice, you will love it! ... show more

  • 36v 55ah lithium battery
Used on an 18ft bass boat with a MinnKota Ultrex 112 (Non-Quest model). I’ve used it maybe 10 days so far since I bought it a few months ago. I was concerned it wouldn’t last a full day, but I fished a couple 11-12 hour days in wind and current and it still had juice left. I typically run it on 4-6 for speed on the dial. I’ve been told not to run it over 8 being a lithium has higher voltage than a lead acid. I bought the LiTime 43.8v 18A charger. I’ve never fully drained the battery but it charges in about 3 hours or less. I didn’t mount it in the boat because I’m not sure that it’s waterproof. I do like the Anderson connector to plug in the charger. My only complaint is that it doesn’t have Bluetooth or a state of charge on the battery. I still give it 5 stars for how well it works for the price. I also love that I went from 153# of trolling batteries (3-27 group lead acid) to one less than 40#. Only time will tell on longevity, but so far I’m happy with the purchase. ... show more

  • 36 volt 55 ah
Style: 36V 50Ah TM
Easy install, much lighter than 3 agm 12 volts, propells garmin force very well. I have only used it once (test run) and am satisfied with it. Used the force trolling motor for about four hrs and when finished it still had 39.9 volts availble.

  • Tournament bass angler
As the title says I am a tournament bass angler who fishes about 3 days a week. Currently it is the spawn and I have been VERY had on the 36v/55ah battery I got. Yesterday I was on the water for 10 hrs and was looking for beds. I have a Minn Kota Ultrex. I was on high the entire day and still had 50% battery left at the end of the day. So far I am very impressed and happy with my purchase! There are a few things I would like to see added to the battery such as Bluetooth to monitor % remaining but other than that … put them in your boat and run them! ... show more

  • So Far So Good
I am using the battery for my trolling motor on my boat. I have not had the chance to get it out on the water yet. I have no idea how well it will perform at this time. My only wish for this battery so far is that it had a Bluetooth connection so I could monitor the battery.
