*Update*
Had my Helix Jr. serviced by Letus. They replaced the board inside as mine was one of the early ones and they thought that might have something to do with it. It didn't. When I got it back I had the same symptoms.
Yesterday I went to the Red Store Hollywood to run some tests. Their Weapon, once more, powered up just fine. Their Scarlet-W had the exact same symptoms as mine (fans on for 1 second then off). So did their Raven. Then we tried their Epic and it also powered up.
So the only two cameras, for whatever reason, that can't start up with the Helix battery are Scarlet-W and Raven. I'm worried that because this is a more niche issue that there won't be a fix for this any time soon. Spending 18k on a camera is no joke... sadly I've had a Scarlet-W for a full month now and haven't used it once.
