I'm ready to buy batteries for my 24 volt 80lb Minn Kota. I've been waiting on the new bluetooth version to come out and now I'm not sure if I want it or not. Trying to determine what the difference is in these two. They are both 100ah. Does the group size of the new one being 24 make it any less run time than the 31? The new bluetooth one says best for 30-70lb but is that for one and not when you are using two? There is an extra $100 off code good for one more day so the new bluetooth one would be $279 a piece.
