I put these in and only been out a few times till this past saturday. Fished 1st actual tournament sat full day in some pretty good current most of the day. After all day batteries were at 82% is that normal? If that's the case they will be perfect. Do they need to be charged or do you drain them farther. Also have the 125 big battery and after running pumps and graphs all day it didn't even put a dent in it after a 15 min run back to weigh in it was at 99%
