DESCRIPTION

When your marine or off-grid power demands are high, you need a battery that won’t flinch. The ABYSS® 12V 350Ah Lithium Marine House Battery is a true powerhouse combining high-performance deep cycle endurance with engine-cranking capability in one intelligent, ultra-efficient solution.

Crafted with a robust 200A internal BMS, Bluetooth® connectivity, and built-in cold weather heating, this Group 8D lithium battery is designed to seamlessly handle high-load devices like Seakeeper stabilizers, chill plates, air conditioning units, electric ovens, and outboard or diesel engine starts.
