The Abyss 3 bank 12V/36V battery chargers are perfect for boats with a 12V house battery, 12V cranking battery and 36V deep cycle battery.
Running two starting batteries and the 36v Abyss TM battery. Didn't want two chargers so this was a perfect match. The unit works great. Giving it 4 stars because the directions that came with it are atrocious.
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
