SO -- no resistors, no diodes, nothing at all in series between the battery and the ESC. The lower the battery to ESC resistance, the better for the ESC, and the cooler the ESC will run.

Thanx!
So Patrick,

Can we use a resistor on the battery to prevent the big spark with 6s setups? Plug in neg, plug in resistor to charge caps, then plug in main positive.
