One Amped Outdoors 24V 80Ah LiFePO4 Trolling Motor Lithium Battery with Charger-Heated can replace your heavy trolling motor batteries for your boat. Weighing just over 31 pounds, this 24V LiFePO4 lithium battery is significantly lighter than a conventional SLA battery, potentially eliminating up to 100 pounds from your boat. Less weight onboard also means less strain on your trolling motor over time. The included waterproof onboard charger features an active heating function that warms the battery when temperatures dip below freezing, allowing charging to start at 32degF. It continues to heat the battery until it reaches approximately 50degF, where it then accepts a full charge rate. You get all the power you need in a lightweight package that reduces the load on both your boat and trolling motor. The whole setup is a win!
