Proper way to run CC BEC PRO on 6s with a 12s system...Updated for EDGE and EDGE HV

http://www.castlecreations.com/suppo...stallation.pdf

This PDF show the CC BEC but the drawing is the same if you want to use a CC BEC PRO with a 12s system but you prefer to run on 6s input.

Advantages- The cont. current rating on the CC BEC PRO is higher on 6s than on 12s...

You can also power up your equipment ( FBL, and RX) before powering up the motor and ESC ...

Not the only way to run the CC BEC PRO but this is my personal preference on my Trex 700's ... and you may also like it too.



If you are hooking to the positive and the High negative then you can damage components so make sure you are connecting as in the diagram. ( I also added a PDF link from the CC Web Site it is possible to wire the BEC on 6s incorrectly on the ICE HV and it not damage the ESC... but using that harness on an EDGE can damage the ESC.) If you follow the examples in the drawings then you will be fine.

Why does the red bold print say "Not applicable to BEC Pro" above the graphic?

Some of the drawings don't apply to the BEC PRO and that is why it is there. One of the drawings at the bottom left says never do this: it is hooking to the High negative and this will cause problems for the HV and the PH. The other Never do this drawing on the right is okay for the BEC Pro but I recommend running on 6s for the trex 700 and 12s as I described above.

Anyone have any idea why the warning is there not to try it on the BEC pro though?

Issues anyone?

What is the amp draw specs? The spec sheet that came with my CC BEC Pro simply says 10 amp max. What is the amp draw limit with a 12s setup?

I found this press release concerning the output based on input voltage..

Read post #3 in this thread....

This is at the top of the page because there are several ways to wire up the CC BEC and it warns not to wire a certain way that does not apply to the BEC PRO as you can wire in Series with 12s... The point of this thread is to show an alternative way to wire the BEC PRO. Guys are always wanting to wire a 12s system on 6s for the BEC so I am simply showing the proper way to do this by using Drawings that also apply to the CC BEC.... The main point for 12s system powering the BEC Pro on 6s is to make sure you are on the low negative...

I prefer to power up my Radio gear on my 12s Heli prior to powering up my ESC and motor... this is just a preference...I use this when setting up FBL system and testing different radio components that require quite a bit of setup.

As you can see in the PDF " Press release the cont. rating on 12s is around 8 amps cont. with a 20 amp peak... with a 6s system you have around 13amps cont. and a 20 amp Peak.

Again I prefer the 6s wiring method as opposed to the 12s because I like to be able to power the radio gear before the ESC and It makes the setup safer for programing FBL systems. This is just a preference. The difference in mah draw from the 2 6s packs is usually like 3-4 % on a meter.... I figure this is actually 100 - 150 mah per flight from the 6s pack with the BEC wired in for power.

I hope this helps clarify the method and the reason I prefer this method.

The BEC Pro is (in)famous for its high failure rate on 12S. So yes, 6S is the preferred method and, as Clint said, this has other advantages too.

Clintstone, Hello. I just picked up a CC BEC PRO and would like to use it on my 8s system. Would you recommend running the BEC PRO on one of the 4s packs, or do you think it would be fine on the 8s? If I can run it on 8s, I would just solder the BEC leads to the series connector instead of the ESC and still have the option of powering the radio gear before the ESC. Also, cooling the BEC shouldn't be a problem with my application.

I believe Clint will agree - but I would run it on one of the 4s packs. The lower the input voltage the higher the continuous current will be.

Question for Clintstone. barzaun mentioned that the BEC Pro is (in)famous for high failure rate when connected in 12S mode compared to 6S. Could you comment on this? Thanks.
