Dumb Castle BEC question

[steve050773]

Okay, I know this is remedial but I want to confirm before sending the wrong voltage to the BEC...

To install a castle BEC with a mamba max in a standard emaxx style vehicle with 2 2s packs wired in series, how do you wire the BEC's battery leads?

I have the battery leads on the mamba max setup in a typical y series configuration, where one positive lead is connected to a deans and one negative lead is connected to a separate deans plug each and then the two plugs are bridged in series.

This page looks like it is telling me that I wire both BEC leads to the plug that sends the negative lead to the battery (the free lead).

But I think I've also seen people with the BEC wired with the black lead on the negative free lead, and the positive on the positive free lead (on the second deans plug).

Here's an example if you scroll down a little and check out Stum's pic -

That looks like the "don't do this" picture #2 on the above link... but I know these people are actually running their trucks...

Thanks,
