Description
One battery instead of three 12 V lead-acid batteries wired in series for a 36 V trolling motor. Group 31 size, 34.1 lb. Example, our math: 1,536 Wh usable at 80%. At a 25 A average draw (960 W at 38.4 V) that is about 1.6 hours.
Xantrex rates it at 4,000 cycles to 80% health, against 400-500 for a typical lead-acid or AGM battery. The Xantrex app shows charge and status over Bluetooth.
Set your charger to Xantrex’s numbers below. Don’t charge below 32°F. Don’t wire these in series. You can run up to four in parallel for up to 200 Ah. Xantrex asks for a fuse or manual-reset DC breaker rated at least 5,000 A interrupt per 100 Ah of battery.
Good fit if: Your boat runs a 36 V trolling motor and you want one Group 31 battery instead of three 12 V lead-acid.
Not the pick if: You want more run time and have a Group 31 Tall space: the Pro-Guide 36VM75 holds 75 Ah.
