Well now!
If my thinking is correct. The bec internal is hooked to the batteries ground or neg wire. With you hooking the lvc on that side. You accually shorterd the
battery out thru it. If you had hooked it on the other wire it would have been
better. It won't read a lvc on all the packs though. You completed the circuit
and fried the esc. The esc was completeing the circuit with the lvc.

The way i see it. You made a smoke boom with that wiring.
