Battery died with fish biting

Last sunday morn G-duck and I just really got into some nice crappie after a slow start when my battery died for the trolling motor.Prolly was good because I went crappie fishing instead in the ocean fishing for big schools of striper (rockfish) that are coming along our coast now so that I would be home in enough time to put the xmas tree up with the wife ,if the battery held up I would kept fishing lol.Calling for 25kt. winds in ocean this weekend so prolly be after crappie or hunting .
