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!

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.

This battery has tripled my fishing time.

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.

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.

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!
