One job, done well.

This charger is built for one thing, charging 36-V lithium batteries at 10 A. Simple, very small and lightweight, and so far works great. I was trying to minimize weight and space this is perfect. Very pleased.

Leander Landrum (Palmetto, US)
Great Service

Prior charger died. I called and explained what the charger was doing and what voltage the battery was showing. The tech at Abyss figured most likely cause was bad charger and sent me a new one. I had the new one 2 days later.

Abyss warranty

I replaced another brand of lithium battery after have 3 failures with that brand in a year along with it right at three months to get the last one replaced, I gave up trying to get a replacement, and after talking to Abyss battery’s (Ryan) I purchased their battery I can say everything Ryan stated that made me choose them came to the test recently after running their battery 1 1/2 years I had an issue it was determined my charger quite working. They if this does not fix the issue they would get a new battery shipped to me. Charger was sent same day I received the new one connected it up and all was well. It’s nice to work with a company that listens to their customers and stands behind the product the way they do, no hassles. I highly recommend abyss to anyone looking at lithium technology ps abyss batter is much smaller than the previous battery and has served me well. Thanks Abyss

Amazing

At first I was skeptical about this charger. But after using it every weekend I can say how impressed I am with it. It was super easy to install. I did it myself. I fish offshore only. I have long runs between spots sometimes up to an hour. And since I have installed this charger my battery has never gone below 90 percent !!! I wish I would have got it sooner. I also have the 36v lithium battery. This combo woke up my trolling motor. It’s like I bought a new trolling motor. Great product.

Love the charger for my new Abyss lithium battery! It’s compact and it was easy to install inside my small console. Love the simplicity of it and its performance. Keeps my battery happy with fast changing. Very happy with my purchase.

Pricey, but works great

I was a bit surprised at the cost, but it functions as expected. Definately gets warm, so be sure you install in a well ventilated area. I opted to set mine up with a portable mount and only place aboard the boat for the few hours needed to charge. Nick was great to work with and their products are fantastic.

36volt

I wish you could or was recommended to just leave plugged in between outings! I leave my boat somewhere other than my house so it’s hard to make sure the battery is charged unless I go and plug it in for a few hours before my trip the following day! I asked customer support and they said not to leave it plugged in like my Noco charger for my other lead batteries.

Abyss 36 volt 72 Amp Hour

I love the battery and charger, just the fact that it weighs only 46 Lbs. and holds a charge for all day offshore in the Atlantic is priceless for sure. Very helpful staff and customer service also having the Bluetooth connection to monitor usage is another plus.
