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
It's not 100% clear what exactly you are attempting to do.
If you use the sketch you posted most recently you will have problems, the 6v batteries are in both parallel and series arrangements which causes the bottom of the 2 6V batteries to short +ve to -ve which is not good. Removing the link will solve this but will cause the charging circuit not to function on the 6v batteries.
You need to either remove the link which makes the short or remove the links which put the 2 6v batteries in parallel and use them in series to make 12v.
A few options for you;
Option 3 can be simplified by drawing it like this;
I like option 3, but is it not shorted? it looks like the original drawing. It sorta looks like that ground is floating.
Thank You for all of your time spent on this.
:)
The last 2 schematics are both exactly the same circuit but drawn differently, both are option 3. There are no shorts, no floating ground.
Follow the circuit lines on the first schematic for option 3
The ground coming from Load2 joins the ground from Load1. The Vcc for Load2 comes from the same point that the Vcc for Load1. Bat1 and Bat2 are in series which creates a 12v battery, this arrangement is then put in parallel with the other 12v batteries since the +ve side of Bat1 connects to the same point as the +ve side of Bat3 and Bat 4. And the -ve or ground of Bat2 connects to the ground or -ve of bat3 and bat4.
Load 1 and Load 2 are both supplied with 12v.
It does make using 6V batteries pretty redundant unless you are planning to reuse some you already have. If you are buying everything to make this setup then you would be better off just using 12v batteries and putting them all in parallel.
Thank You, RICH!
