Trolling Motor Batteries.

I fish hard! I had 2 Li Time 12v 100ah batteries and I used them in a tournament. I ran my trolling motor on 10 from 7:15 am until 2:50 pm and they went dead. So I upgraded to the 12V 165Ah and have fished 2 tournaments with them and no issues so far! Great Batteries! The 12V 100Ah would definitely keep up with some one who doesn't fish as hard!
