A new paranoia is sit in my mind lately: between parallel/serial connectors, switch etc, I might have half meter (doubled) of cables from battery to ESC. Do you think it’s safer to throw a couple of capacitors in series? Near the esc …
Normally every ESC has some low ESR caps to even out inductions. It does not harm to add a couple of extra ones, but usually the ESCs are designed for up to 50cm cables.
