    • 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

I have had this battery for about a year now so figured I should leave a review. First off the battery is super light and relatively compact for a 36v battery. I use it on a minn kota 36v 112lb thrust ipilot trolling motor on a 25’ bay boat and can reliably without any loss of power use it for about 6-8 hours of use in a fairly decent current. It’s doesn’t take long to charge and it seems to not bleed off as much overtime. I highly recommend this battery if you’re like me look for something light weight fairly compact and very reliable when you need it. ... show more

Review Image by Rachael Albertson
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

    • Trolling Battery
This battery has exceeded my expectations. I have 36V 112thrust trolling motor that use on a 24’ CC and this battery has given us more than 8hrs of running time. It could probably go even longer. Super nice and light.

    • 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

    • Amazing solution for trolling motors!
I replaced 3(140lbs) of lead acid batteries with a single litime 36V battery and could not be happier. The battery runs all day under heavy load and keeps going.....great product!

    • 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.
