I absolutely love my Abyss Batteries. Lightweight and reliable! The phone app is incredible. You can check your battery life and all the functions, cells, and the life signs of the battery. I can now run a 36 V trolling motor on my airboat and not have the weight factor anymore. Absolutely incredible!
If you're looking for service after the sale, these are the people. These guys stand behind their product like noone else.
One of the only things that can separate a battery company from the competition is their warranty. I had issues with my battery and found out that I was the first person to make a warranty claim, which speaks to the durability of the batteries. They sent me out a new one that I received the next day. Great customer service. I would highly recommend.
