Controller Tray Rivnuts Installed

I replaced all twelve of the M4 nuts and bolts on the controller tray with M4 Rivnuts last night. It meant drilling out the 4mm holes to a fraction over 6mm. The last two were a pain as I managed to chip the leading edge of my 6mm cobolt drill bit. Anyway, now the two charger stacks and the Fuse/Contactor box on the tray can be removed easily. I have added the daughter board to 8 of the chargers so only four to go. The low current setting varies from 230 to 350mA across the chargers I have modified so far (I want 180mA) so I hope my new shunt wire arrives soon.
