@LeoDJ@chaos.social you can't just run a fat pre-charge resistor in parallel with the contactor?
That's what we do on our #ppprs karts, but we have a manual contactor switch and wait for many seconds to watch the voltage meter go in to range. And we don't care about parasitic loss because we pull the batteries between races.

@poleguy@mastodon.social Haha, cool solution :D I *could*, yeah. But I wanted to go for this solution ^^ Mainly so I can leave the battery in, if I want to, because the plan is to have cable lugs screwed to the battery's contacts (it's meant for screwed connections). Connectors for 500A get expensive and large *quick* :D And also to have a switch that completely powers off the whole system should anything happen.
