12 volt battery will cause too much flow. Tried it. Drain cant keep up. Fomen, not sure why you think the 6v battery is incapable. Ive had my original battery for years and still running like day one. I keep everything alive from pinhead chovies to giant macs, and I overstuff with bait. Im talking 10 hour days! The only baits ive EVER had roll on me were macs that deep throated my sabiki. I would say you are doing something wrong if your hobie bait tank is not working right. Soldering connections with marine grade shrink tubing is superior to your butt connectors. Another thing I suggest is eliminating your switch from the tank. Seemed like I had better flow after wiring straight to the waterproof battery connector. And lastly, charge and discharge your battery properly. I can fish two, ten hour days back to back on one charge with my tank and "incapable" hobie battery with no problems, I would look elsewhere...
