Description
Run a 24 V trolling motor off one battery instead of two, in a standard-height Group 31 space. It is 25.6 V nominal and stores 2,304 Wh (our math: 25.6 V x 90 Ah).
Built-in heater, Bluetooth, a state of charge gauge and NMEA 2000. Pro-Boost holds back 10% of capacity as a reserve. Pro-Guide’s rough guide: about 3 hours on a 24 V trolling motor drawing 30 A. Need more run time and have a taller box? Look at the 24VM115.
Charge it to 28.8 V, 45 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: Your 24 V trolling motor battery sits in a standard-height Group 31 space and you want one battery instead of two.
Not the pick if: You want more run time and have a taller box: get the 24VM115.
