typical wiring in parallel

[Doby]

Fair enough,,,but Castle really needs to get their you know what together and make their instructions a tad more clearer for the rest of us idiots out there, I'm sure LiPo and I are not the only ones running this configuration.

hey I also thought you could seperate them with no problem...and if your doing it and its working than maybe you can but I do know that your warrantee is shot if you do

here is my take on this and i could be completly wrong....it's just my assumption



in looking at the 240 it looks to me like they have taken two 120's and somehow made them work as one unit and this is why they have to stay connected at the esc boards

sound stupid?...maybe so

...there must be a reason for Castle to install 2 red and 2 black wires...
If not, why not just input one red and one black to make our and their life and the warranty easier. There is so many types of wires out there, 10 gauge, 12 or 8 whatever.

Doby the power boards aren't interconnected. So the potential for having a ESC failure if your packs aren't in near the exact same condition or state of charge is there.
Or like you said "one pack isn't connected" or becomes disconnected.
I agree, perhaps it could have been made a bit clearer in the instructions.
So fix that time bomb and get out and have some fun!!!!!

Looks like I will this weekend.

Thanks Doug!

Kitchener pond?
What day?

Power boards are interconnected. There is no need to connect red with red and black with black. It is all done inside, right where the cables are attached to the board. Please have a look at the picture.

First is CCHV180...

and CCLV240...

Here ya go Nick.
I bind the wires together with 18 ga. solid strand copper wire then solder them with a good hot iron. Get the job done and get out.
If you need the wires to bend back over the control as I did in this case, keep that in mind before you strip and solder them. Make sure all the wires are the same length before you start.

Sorry for the dark pics, I'm no Jim Clark.
Hope this helps.

This will increase resistance and temperature if running bats in P configuration...

Power cables, red and black are interconnected inside to make these two boards receive same power. Plug and Play if you are running P config. Playing with splitters and so on wont help to keep temps down....

Hmmm, I wonder if the motor leads being connected have anything to do with the results of your test?? I'm no electronics expert but there may also be some feedback through the capacitors.

I think I'll continue to follow the manufacturers instructions.

Really?? As opposed to what? Please explain.

Well, from what I have learned:

-larger connectors = Less resistance
-shorter battery cables = less resistance
-the least the custom connections = less resistance

all that will help to keep temps under controll and deliver cleaner, stronger, less distorted power, right?
Adding extra cable wont help with above. There is enough wire with bats and ESC to have us install 5mm connectors to eliminate power loss and temp increase so when you extand power cable, how will that not reduce the juice we need to go to motor?

1.0 Features of the HYDRA HV Controllers™ :
• Extremely Low Resistance
o HV 60 = .0015 ohms
o HV 120 = .00075 ohms
o HV 180 = .000375 ohms
o HV 240 = .000182 ohms

Hey, I am new in this hobby but I am sure there is a little sence in what I have learned so fare.
I am only saying the power cords are interconnected inside. If there is no need to add more cable and welding and connecting, why do it?

I personally believe that knpc has it correct.

If truly these boards are wired with independent input leads, then it would seem that each board is acting 'independently' input wise. Since the variations would (or should) be minimal initially when not wired in common, then all is well.

However, as the batteries discharge, a disparity in input voltage will occur and then it would be up to the transistors to react to this difference accordingly.

Maybe this difference is not enough to discern initially, but it would seem that this could be a recipe for a tug of war that could end up in one plate attempting to dominate the other and end up exceeding its rating and causing damage.

I guess I agree with those like Mr. Spock uhhh... Smock, Fluid and others.

Again, just my 2 cents...

Robert,
There was no wire added to the ESC I posted pics of in post #10.
Good luck and have fun!!!
