12V SEAL- LiFePO4 - 228Ah - 3.0kWh + FREE Lifetime Customer Support!

BigBattery prides itself on having a lithium-ion solution for whatever you need to power, and that’s why we’re so proud to be able to offer you a safe, powerful 12V solution for your boats and other marine applications.

This heavy-duty marine lithium battery is equipped with 316-grade stainless steel, a watertight double seal – both rubber and foam – and an extendable LED voltmeter so you can install the display in your boat’s control panel. These additions come on top of our already lengthy list of incredible features such as our advanced BMS, brand new LFP cells, thermal management system, and 300A fuse. With 3kWh of watertight, non-corrosive power, you’ll be sailing and speeding across the water in no time!

And as always, it requires zero maintenance, it’s easily installed, it’s made right here in the US, and is guaranteed to be the lowest cost battery in its class available today.
