Antispark xt90 and focboxes

Some help needed. I have the battery with regular xt90 and xt90-double xt60 adapter. And my antispark pcb button still not delivered. Can I use xt90 antispark between battery and adapter to power up the whole thing and not fry everything?

A xt90 antispark should be enough How the name said it’s also a antispark Just not so nice to switch on and off

Ok, thanks. Will try with 1 focbox for safety, :slight_smile:
