One 24V battery replaces two 12V lead-acid or AGM batteries wired in series, so anglers running a Minn Kota, MotorGuide, or Garmin Force trolling motor can drop roughly 60 to 80 pounds off the bow while gaining a full day of steady, dependable power.\u003c\/p\u003e\n\u003cp style=\"font-size: 18px;\"\u003eUnder heavy trolling use, one battery delivers a minimum of 6 hours of continuous power. Running two batteries in parallel extends that to 12 or more hours for long tournament days. Many anglers finish a full day of fishing with a large reserve still showing on the app.\u003c\/p\u003e\n\u003cp style=\"font-size: 18px;\"\u003eBeyond the water, the same 25.6V nominal output makes it a practical building block for 24V solar and off-grid systems, cabins, and auxiliary deep-cycle power. With 2.04 kWh of usable storage in a compact BCI Group 31 case, it fits standard battery trays and installs like a familiar marine battery.\u003c\/p\u003e\n\u003cp style=\"font-size: 18px;\"\u003eBuilt-in Bluetooth lets you monitor state of charge, voltage, current, temperature, and cycle count from your phone. An integrated Battery Management System protects the cells, and a 10-year warranty backs every battery.\u003c\/p\u003e\n\u003cp style=\"font-size: 18px;\"\u003eThis model is available in two versions on this page: the Standard 2480-BT with low-temperature charging protection, and the Heated 2480-BTH, which adds a self-heating element so the battery can charge in freezing conditions.
