I just bought a Humminbird 525 and i'm powering it up with a 1600 mah r/c car battery. Ran it for over 4 hours no prob, still plenty of juice for my kids to play with thier car in the driveway for a good 20 min.

didnt make me a better fisherman, but i can see the fish now though. My time will come when I wont make any rookie mistakes, last time I had a hook up, line peeled off, set the drag tight reeled it in for a good 5 secs, line went limp so i jerked on it a few times, line peeled out again, reeled it on for a few, yanked it, GONE.... Next time...... I'll get that SOB! I cant get over it. Drinkin now with my buds

LATER!
