PumaBassXS,Ive run BassCats with the 3 battery setup for years, using both brand of trolling motors. Like BCB said, you must keep all three units charged, AND—Im also a firm believer that you need to run big batteries–all 3 of mine are 30-31 series Trojan SCS 225. I use a big deep cycle trolling motor battery as a cranking battery, and have NEVER HAD a problem running out of juice.The times Ive seen issues in other boats, I always found a 24 or 27 series cranking battery in the mix.Just my experience, over about 15 years.Enjoy a great boat, and the Family that supports them.Mike Whitten/Germantown, TN
