BEC wiring question / thoughts

[dillwhacker]

with only the 'top' battery fitted and there was 0.75v drop. That sounds like what you would expect if there was a diode of some sort in there.

Thanks Grumpy, nice one.
TBH I bet all the BEC manufacturers have figured this out and it's not an issue, but just interesting that there's not much mention of it.
Cheers!
