Solve battery drain issues? - Rewix - 07.01.2020 Hi, I'm not sure if a post for this has been made before, I'd like to ask where do you supply power for the raspberry, so it's not constantly on and draining the battery overnight? I have installed it in an E38. Thanks and Best Regards! RE: Solve battery drain issues? - maggus - 08.01.2020 there are multiple aproaches for that: - controlled shutdown/power up - ups for the pi - and i am pretty sure some more all have advantages and disadvantages ... it all depends on what your goal is. my will be that i dont want the pi to be powered up. i will use the VA (VerbraucherAbschaltung aka 15 min pin, not sure how the pin is called in english, it basically is a wake up pin, powers up when car is unlocked and powered down after like 15 min of idle time). i hope this helps a bit ;-) RE: Solve battery drain issues? - N3mesis - 13.01.2020 There is a red/yellow consumer wire that is usually connected to your interiorights, check your trunk lights for the red/yellow wire. Like maggus said its powered up from the get go and powers down 15min after locking the car. I dont recommend using the consumer wire for heavy load, instead use a relais and get the power directly from the battery, dont forget to put a fuse in it.
