Hooking Both Serial And Par At The Same Time.

Skip to comments   Jump to end

Any Engineers out there besides Fred? He can't post right now.

I saw a drawing that Josh made, I think. It sounded pretty interesting.

I will be running two 12vdc and two 6vdc batteries. It was said that I could use 6vdc for one EZB and 6vdc for the second EZB. Then use them in Serial as a 12volt setup to charge all of the batteries at once. Is this possible? Josh, have you put that in operation and does it work. Or, is the paper a theory. I mean, it sounds like a good idea to me. But, other people on the net has said they will short out. So, what should we do? I am just trying to find out.

It seems like it would work for me.

Thanks,

Mel

I'm not convinced that this would be the correct way to go about things, even doing away with the common ground. There is just too much scope for something to go wrong and damage batteries, controllers, accessories etc.

Is there any reason why the EZ-Bs would need 6v to them rather than the full 12V? As in, connect the batteries in series and power each EZ-B from the +ve of Battery 1 and -ve of Battery 2?

I orignially ordered two six volt and two 12 volt batteries because I was going to run an ITX motherboard. But, I have since decided to use a netbook. So, I really don't have any 12v devices except maybe the motors. Someone said that the motors run better with 12v. This is on the Omnibot.

What do you think?

Personally I don't think that would work. I've only had a very quick look but when I get chance I'll trace out the schematic and redraw it so I can understand it better. But the link between the 2 6V batteries is linking Vcc and Ground together, trace it back it shorts across the + and - of the 12v charging source and across all batteries.

I see what you mean. That is why I wanted to check things out before I do it.

Anyone else can jump in when they are ready.

The next question is: Can I use both of these 12volt batteries to power the motors with a 2.5 Amp H-Bridge?

If the motors can accept 12v yes.

It is the motors on the Omnibot2000 robot.

I usually have a common ground because of noise generated in the system. I am scratching my head on this one. The schematic seems ok, but then it doesn't.

Still confused. I may just hook all the stuff up individually.
