GND (battery leg connector) <> VCC
Used kapton tape to make sure it does not short anything.
Extended the cap leg with a black wire (which is low quality as it melted somewhat as you can see 
)
I do have way smaller capacitors which could fit right on top. But I do not have the equipment to measure if the solution is working with like 1/10 of the that capacity. So figured, first try with the exact same setup.
I might try and contact GNIF (Video owner) to know what to do.
The door next to my HA setup (POE Zigbee) like 40cm away, empties out the fastest (opens maybe 50 times a day).
