what is the cell limit on sv27 esc

[pugman2]

can i safetly run 2- 7 cell packs without toasting the esc? dont have any cooling issues whatsoever with props and motor now running hills ib 6 cell pacs would like to run 2 ib 4200 7cell packs

[Ocean Racer]

from what ive heard you are fine but wait for some more advise to come along to ethier prove or disprove this.

[H&MWill]

Yes 2 7 cells are fine but do away with BEC and run a seperate receiver pack.

[hex-dj]

pugman 2... you can have 14 cells,but with a trick you can have 16 or 18 cells...with bec battery of course.

As long as a couple of those cells are toast.

[hex-dj]

(H&M) I agree...

[kssi]

i run 16 with out any problems, on its own reciver pack though

[ETOWNE]

i run 16 with out any problems, on its own reciver pack though16 MPH that is.....lol

[hex-dj]

Maybe he will do much better if he runs unparallel cell packs and unmatched cells,so that boat can be fully raceable...LOL

[Apples1]

is that how it works , 1 cell per 1 MPH, thats an easy fix to hit 60.
i reckon i have 80 or so cells lying around lol

[pugman2]

so i just plug a rec pack and switch in . and it overrides the other sorce ? or do i have to cut some wires

Don't cut wires...two ways I do this

1) simply remove the esc's red wire socket from the plug and fold it back onto the wires and tape/heat shrink it in place
2) make an extension up that has the same thing done to it or has had the red wire cut off.that way you're not messing with the esc's plug
I've included a couple pics in case my words weren't clear enough

If you don't mind me asking, why do you disconnect the BEC? I have been running 14 cells in my supervee without unhooking the BEC. Am I gonna ruin something or is that just a personal preference??

thanks

mine started glitching

The BEC inside a ESC can only regulate so much voltage that is connected by a battery by design. When you conntect more voltage than it can handle, it's not capable anymore, so glitching, heating, etc occur. So, you disconnect the red wire to not get this voltage and supply the ESC with voltage it can handle, hence the seperate battery pack.

Hope that clarifies.

Peace~

My crazy brother is running 16 cells with his SV27 and using the standard BEC to power everything. Strangely enough it all works and has not flamed out even with a great deal of use. Not advisable, but just thought it was interesting.

Sorry to bring this one back up. Is it still an issue to run 14 cells w/ stock SV27s?

[Brushless55]

Wow!
16cells on a SV27, wonder what kind of speeds they get?

If your gonna run 14 cells then run a castle BEC or a receiver pack.

[z400]

LMAO @ 16-18 cells.

Good luck with that

[Brushless55]

18 cells? oh my!

What is a castle BEC? I know what a receiver pack is.

Castle Battery eliminator circuit.


Castle is the make/brand
