Feather-Lite Batteries Is at it again, setting the industry standard even higher. The newest Marine Starting Batteries offering the first of its kind, built in Jump-Starter. This means after a long day of fishing or floating around on your boat with radio there is no chance of getting stuck out on the water because of a dead battery. No need for a jump-Starter, jumper cables, or calling someone for a tow, simple open the console gold the button on the battery down for 5 seconds start your boat and drive away. An optional wireless key fob unit is available like offered in our Automotive units but typically not recommended for marine applications.

So, don’t Get stranded with a Dead Battery.


All Feather-Lite Batteries Marine Series batteries utilize FLP-Circuitry built -in to the unit specifically designed for the application. So in the instant of starting batteries with built-in emergency back-up, these units will shut down the battery when the voltage drops to a certain point to protect the battery from damage and to have enough capacity in reserve to run all the systems on-board boat correctly once the built in jump-starter gets you started back up.
