Description
Run a 24 V trolling motor off one battery instead of two. Pro-Guide’s rough guide is about 3.8 hours at a 30 A draw. The 24VM115 is 25.6 V nominal and stores 2,944 Wh (our math: 25.6 V x 115 Ah) in a Group 31 Tall case.
Pro-Guide built it for marine and off-grid use, with a 150 A BMS, a built-in heater, Bluetooth and NMEA 2000. Pro-Boost holds back 10% of capacity as a reserve.
Charge it to 28.8 V, 10-23 A standard, 57.5 A max. Pro-Guide’s rating is over 3,000 full (100%) discharge cycles, with 5 years of free replacement under warranty.
Good fit if: You run a 24 V trolling motor and want one battery instead of two: about 3.8 hours at 30 A, per Pro-Guide.
Not the pick if: Your box only fits a standard-height Group 31, not a Group 31 Tall: get the 24VM90.
