Optima Blue Top Batteries
Plenty of power for the Terrova bow mount and now I can have electrics, pumps, riggers, and everything else going off the main battery all day long with only the T8 kicker running.
When the batteries on my Salmon boat start to fail I will be replacing the Interstate batteries it came with and they will all be Everstart MAXX 29-DC's.
To compare batteries for a trolling application, look at the reserve capacity. This is the discharge time at 25A draw, which is a good measure for trolling duty.
Can't beat Walmart or F&F standard flooded deep cycles for bang for your buck, tho.
