All, I have an 03 cougar and would like to know if there is a good modification to allow for a 4th battery. I have a 36 V Minn Kota Maxxum 101 Trolling motor, running on my two Trojan SC225 and a Trojan Trolling/Cranking with a Stealth I with the AC option. Since I have owned this boat, I constantly struggle with running out of batteries even though Ive bought some of best batteries with the greatest Reserve capacity on the market. I am hopeful some folks have implemented this 4 battery modification.Thanks,
