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

Rusty Broussard

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.
