[quote mojorizing][#0000ff]No one's offended. Your portacruise post is saying that you run the batteries in series? Use a DPDT switch wired to run in series or parallel. Am I right in assuming this? So you run 24v. Select 12V at double marked capacity in parallel or 24V in series at marked capacity on the gels. And the motor's standing up to it. Yes, but only because a smaller prop which taxes the motor less while spinning faster and producing more thrust is used. If the original prop is used, motor would burn up.
Why two batteries for 24v. Menu of options increases to meet the situation. Go at 2 mph in parallel for 6 hours at 12v or 4mph at 24v for 2.5 hrs for example. All from a motor rated at say 2mph max for a pontoon. If one battery goes down, no 24v available, but you have a limp home mode at 12v from the other one. Bottom of line 12v trolls cost MUCH less but are tricked into perfomance of premium 24v motors. If you find a special deal on non-standard voltage batteries (like say 14v drill batteries) , you can run any voltage from 9 to 28v.You say 'turbo' speed. That's a lot of weight. Two half capacity gel cells weigh only slightly more than the equivalent capacity 12v, yet give same capacity and advantages above. Also, I run on much smaller scale with a tiny troll motor for a pontoon, 6# total weight. Heres an example motor from design forums that weighs about half a pound and can produce close to 1 hp at maximum [/#0000ff] [url "http://www.boatdesign.net/forums/attachments/boat-design/31941d1242956976-pedal-boat-design-turnigy_motor.wmv"]http://www.boatdesign.net/forums/att...nigy_motor.wmv[/url][#0000ff] Even with two smaller batteries. Is it just an experiment? No, ran a minn kota 12v 95W for about 10 years in twice weekly use like this- several years back-still have the 95W with no damage apparent upon disassembly and inspection.
But I'd like to know what is your reasoning behind it (it's all curiosity). I have a MinnKota 5 speed that I use once in a while, I'm not really in a hurry to go from point a to point b.Neither am I under normal conditions in a pontoon so I select the 12v speed with the most efficient prop at 1.5mph trolling speed. But sometimes in river fishing when you are fishing in front or behind rapids, you need more power to hover or get out of the way of kayakers, etc. Same for lake with winds and jet skis. If I want to get there fast, I use my oars. Very little effort and a little exercise to boot. You look younger and stronger,no offense, but no way you can keep up the effort for hours with even one of my smallest motors. Rowing small pontoons slowly for short distance positioning is OK, but extremenly inefficient, tiring and slow compared to a canoe or kayak. Float tubes and pontoons are just not designed for long distance or fast travel, like kayaks or canoes, IMHO .'t get me wrong, I think it's kind of a cool idea, although some here might think I'm trying to get in your face. I just want to know what the advantages are. Your fishing style or the target fish, or just an inventors brainchild I mostly like trolling, seeing the scenery change and covering miles of ground to zero in on pockets of fish in rivers where can't use sonar and sometimes lakes. Theres rainbow, whites, blacks, stripers, cats and perch and a few others in rivers nearby..[/#0000ff][/quote
