Re: phase charging 3 batteries

if you can produce 100 amps from a 30 amp alternator you have just solved the world's energy crisis and you will be a gazillionaire.

Sufficiently advanced technology is indistinguishable from magic.

I'm getting to be an old fart. I was there when they said you couldn't clock a computer over 1 mhz. We're now about 4000 times that speed and climbing.

The question I posed is this:

If you could get full service for your batteries out of your main engine for $600 in parts and a couple of hours of time, and not do any major wrenching on the motor, would you buy it?

I would pay a million dollars if I could get 100 amps @ 12V if my alternator was putting out 30amps @ 12V.

I think It'll only be about $600, but I'll put you on the list.

Nicola Tesla was dissed by Thomas Edison for dreaming up the polyphase system of electrical generation and distribution that we use today. The difference is Tesla's system wastes very little power, and is capable of long distance transmission, and Edison's DC distribution system wasted much of it and was limited to local distribution, as in 1 mile. Tom's system is gone, Nicola's is what we use.

I think I know what you plan on doing...DC/DC convertor.

You still aren't going to produce 3x the watts on your outputs which is what you said in your original post.

Yer on the right track, and believe it or not, the power is there. It's just that the simple rectifier wastes most of it, and reflect a great part of it back into the stator where it is lost as resistive, hysteresis, and eddy current, all making heat where you don't want it. That's mostly recoverable with the sufficiently advanced technology mentioned before.

Do you really have a million dollars?o:)

Is there a diagram of the charge panel referenced on page 12?

Just a guess at this point but the single pole/single throw switch that selects 12V or 24V means that when you are in 12V mode, only one of the batteries is being used in 12V mode and this charge panel is connecting the positive of one battery to the negative of the other.


Bruce, I have looked and can't find a diagram, but believe you are 100% correct in your thoughts.

This is what it says at top of page 13....
"BOATS WITH CHARGE/RUN PANEL"
"If your boat is equipped with a charge/run panel you will have four (4) trolling motor leads at the rear of the boat. Connect the positive (+) leads to the positive (+) battery posts and connect the negative (-) leads to the negative (-) battery posts (See Figure 2 or consult you boat owner's manual)."

Figure 2 is what I posted above. I suppose I should have included this when I posted that above.

Even though I've been a bit scarce, I really would love to get something like this going and I finally should have a bit of time to mess with it.

Thanks for all the help.


As for the $600 thing, I'm not sure I'm interested in spending that much, but then again I don't run my troller a bunch. I just want something to keep them topped off, so they are there when I need/want them. Also, I don't think on most bass boats with over a 150hp motor the weight of a couple of batteries is going to make much difference in top speed. Of course, I'm not a tournament fisher either!!

Re: phase charging 3 batteries

Are any of you still watching this thread?

I know I let it kind of die off, but my boats been covered all winter. I would now love to get something wired up.

I still have these diagrams saved if I should repost, but my main question at this point, is where the starting battery comes into play. Do I leave it wired as is from factory or does it get wired into one of these diagrams so that while the other batteries are charging, it gets isolated? The other question is, will all batteries be charging at the same time or do they get charged one at a time?

The diagrams posted by GQ say starting battery on the top diagrams, but I'm not clear if that means I'm tieing into that batteries wires or what. I think the rest makes sense finally.

Thanks for any help!

You need to host them elsewhere and put a link to where you hosted then at. Looks like it worked fine for you before.

I just thought there was an easier way then to upload them somewhere else.

Here are the diagrams I have....

Re: phase charging 3 batteries

Are there 2 relays or 1?

GQ, listed relay "C" and relay "CB", but I don't get that part. Is "C", just the part of the relay that controls Battery 1 and "CB" is the part that controls Battery 2?

I don't believe that is the case, but I don't see how/where the 2nd relay comes into play. If there are 2 relays are they both wired the same as shown in the lower part of the diagram, with the exception of how the different features from the top part of diagram tie in? Then the other question pertaining to this is the C-1, C-3, CB-1, & CB-2, is the number supposed to corrolate to the number on the diagram?

I am trying to put together a detailed drawing of how I feel this works, but I am stuck on those parts. I agree some of the features are more than needed, but it would be nice to have an amp meter to see the charge level on the two troller batteries as well as seeing when those batteries are chargeing.
