The Millertech 36V 60Ah Marine Trolling Battery lets you replace three heavy lead-acid batteries with one lightweight lithium battery that keeps your 36-volt trolling motor running at steady speed from your first cast to your last.\u003c\/p\u003e\n\u003cp style=\"font-size: 18px;\"\u003eThis single Group 31 lithium battery takes the place of three 12V Group 27 lead-acid or AGM batteries, cutting more than 50% of the weight and clearing space in your battery compartment. Because it uses a flat lithium (LiFePO4) voltage curve, it holds strong power deep into the day instead of fading like lead-acid, so your Minn Kota, Motorguide, or Lowrance motor does not slow down as the charge drops. Anglers run it on bass boats, walleye and multi-species rigs, bay boats, and pontoons with 36-volt trolling motors up to 112 pounds of thrust.\u003c\/p\u003e\n\u003cp style=\"font-size: 18px;\"\u003eCheck your power level from your phone at any time. Built-in Bluetooth links to the MillerTech App and shows how much charge is left, how much power the motor is pulling, and how long charging will take, so there is no guessing about whether you can make one more pass. A sealed marine case handles salt, spray, and vibration, and a 10-year full repair or replace warranty backs it for the long haul.\u003c\/p\u003e\n\u003cp style=\"font-size: 18px;\"\u003e\u003cstrong\u003eChoose the variant that fits how you charge:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"font-size: 18px;\"\u003e\n\u003cli style=\"font-size: 18px;\"\u003e\n\u003cstrong\u003eStandard (3660-BT):\u003c\/strong\u003e The right choice for most anglers.

Both variants accept up to 60A of charge current, and MillerTech lists a recommended charge current of 15A. The 36V 15A on-board charger matches that recommendation, while the 25A option charges faster to get you back on the water sooner, both charge safely. On the Heated variant, the heater turns on at 32°F and runs on charger power, so in cold weather keep the charger connected to warm the cells before charging begins.\u003c\/p\u003e\n\u003ctable style=\"font-size: 18px;
