I’ll stop lurking and jump in to add a tangential solution that I use on my raceboard
The caps do discharge when I stop pre-charging with the external resistor (before I plug it in directly), but as long as I’m quick the AS150s can handle that easily.
Not the most ideal solution, but the only time I’m plugging in the batteries is after maintenance/modifications (because my G300 ESCs have a built in power switch)
