    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

    Wow

    Great day on the water -
    I surprised my fishing crew with a great new toy , aka the “Abyss Battery”
    No crazy heavy box, no crazy cords….

    I had buddy with cord problems, batteries problems, battery died. I didn’t have that issue at all. Easy plugin, with 8hrs of continuous use. I still had 75% left on my battery when we headed back to the shore.

    All my boys started asking me, where did you get that?

    I highly recommend this Battery

    The Abyss Battery trays are easy to mount and securely hold the battery in place. Best option I've seen for securing batteries in a fishing boat.

    Abyss Lithium Project

    Converting my boat from lead acid batteries to Abyss lithium batteries has proved to be a great idea. Not only have I improved my reserve capacity, the lithium batteries charge in a fraction of the time compared to lead acid batteries. I went with a 36V 105 Ah battery for my electric motor and a 12V120Ah lithium for my house battery. I’ve never enjoyed more DC power in a fishing boat!

    THE BEST POSSIBLE! GAME CHANGER FOR SURE!!

    I have to admit I was skeptical at best as to how these batteries would perform. Granted I have only used them on one trip so far but I put them to one Hell of a test deep dropping and bringing in slob grouper and big ARS on nearly every drop for 9 solid hours of fishing and they never slowed down. When we were done I still had 50% showing in one and 75% in the other. I’m a believer now - get you some!

    My first move to lith.

    The battries are first class along with customer suport.
    If you are using acid core or adm, Lithium is the way to go.
    My only complaint is for a first time user, I had to call customer support because of the limited owner info sent with the batteries.

    Top tier knowledge and service, and top tier products to match

    Ryan and Abyss are top notch. Super knowledgeable, super accommodating. And their products are second to none. Best charger options in the LiFePo4 marketplace, and it's not even close. And the batteries are LEGIT. I wouldn't waste any time looking anywhere else for lithiums and/or chargers

    Pulley Ridge!

    Once I ordered the battery I received it in a couple days which I needed as my Ridge trip in the Yankee Capts was
    Coming up fast! The 1st day of fishing (500 - 800’ deep) Sun up to sun down 3 to 4 pound sinkers with strong current the battery lasted all day but was in need of charge at the end of the day. The next 2 days less current 2-3 pound sinkers the battery lasted 2 days no problem. I would
    Highly recommend this battery

    Commonly Asked FAQ's?

    Amp hours (Ah) in a battery can be comparable to the size of your fuel tank in your boat. More Amp hours = More run time!

    There are many factors to consider while choosing the right battery for your boat. Every boat is different by weight and size.

    12V Dual-Purpose Batteries: We offer a range of high output dual-purpose lithium marine batteries that can be used for both starting and deep-cycle applications. 

    Our 12V dual purpose marine batteries are designed to power high load marine devices and have been used as a solution on center console boats that lack a generator and proper battery system to power SEAKEEPER, Marine Boat Chill Plate Refrigeration, and 360˚ OMNI SONAR.

    24V Trolling Motor Systems: If you have a skiff between 16ft' & 22ft' in length and are a casual fisherman, fishing after work or only a few hours out the day at a time (4-5hr) then our 24V50Ah or 24V60Ah is right for you.

    If you are serious fisherman, tournament angler or guide, and fish for more than > 6 hours at a time, we recommend our 24V80Ah or 24V100Ah battery set up, Remember More amp hours = more run time.

    36V Trolling Motor Systems: Our 36V60Ah lithium battery has been installed on over 150 different types of center-console boats. This single battery has been tested to last over > 8+ hours for boats up to 34'ft in calm conditions. (Run time will vary depending on the weight, size, & sea conditions).

    If you have a larger boat and want to be a able to use your trolling motor all day in 2'-4'ft seas, we highly suggest running our 36V 72Ah or 36V 105Ah battery systems. We have designed three different tiers of batteries with different amp hours for this specific reason.

    Our friendly staff is is more than happy to guide you in the right direction to assist you in getting the proper lithium battery set up to best suite your needs.

    If you still are unsure of what battery set up to choose from please reach out and give us a CALL (855-719-1727) or send us email info@abyssbattery.com

    24V Trolling Motor Systems: If you have a skiff between 16ft' & 22ft' in length and are a casual fisherman, the 24V 50Ah and 24V 60Ah Trolling batteries are expected to last between 5-7 hours on a single charge depending on the tide and wind conditions.

    For the 24V 75Ah and 24V 100Ah battery set up, Remember More amp hours = more run time. Based on various fishing conditions and boat size both of these batteries have been proven to provide up to and over 8 hours on a single charge.

    36V Trolling Motor Systems: The 36V 60Ah deep cycle lithium battery has been installed on over > 400 center console boats. This single group 31 battery has been tested to last 8+ hours for boats up to 34 'ft in calm conditions. 

    If you have a larger boat and want to use your trolling motor all day in 2'-4'ft seas, we highly suggest running our 36V 72Ah or 36V 105Ah battery systems. Expect up to 12+ hours of hard run time with ether of these batteries.

    (Run time will vary depending on the weight, size, & sea conditions).

    While we highly recommend using our onboard marine chargers, they're other compatible lithium chargers out there that will work with an ABYSS. They include; the Stealth I Charging , and Power Pole CHARGE®. Our batteries have been tested and work flawlessly with both charging systems with no issues. We only recommend using our charger because it is programmed and specifically designed to charge our batteries. Our marine lithium battery chargers come equipped with built in safety features along with a pulse wake-up mode function that automatically restarts your battery if it has been fully discharged and in protection mode. All these features built into our waterproof chargers are designed to make your experience using our products that much easier and extend your battery life cycle. The choice is yours.
