Hello to all,
before I describe the specifics of my - humble - ask to you, I hope you will kindly bear with me on all the inaccuracies or mistakes I may write (I am as noob as it gets regarding electricity).
I also read beforehand several threads which contain all plenty of much instructive information...But I am not in capacity to translate them into a solution for my case.

Kind regards,

1) Context
- a) I have purchased a 70MAI A800S + OEM hardwire kit
- b) I wish to have a parking mode connected to an auxillary battery/energy storage unit (Target : at least 24hours autonomy)
- c) It must allow me to easily switch a depleted energy storage unit for a fully charged one. Assuming a 24h autonomy, I could thus come and swap the battery once per day which is fine for me.
- d) And for the lack of originality, I am looking for a price-savvy solution. If required some DIY would be more than welcome (always an occasion to learn something)
- a) It seems A800S needs to be hardwired for the parking mode to work. Is there a way to hardwire a classical (i.e. non dashcam) powerbank to the A800S ? The OEM hardwire has a 12V-24V input, and usual powerbanks seem to have a 5V output so I infer that is already one matter to deal with.
- b) If so, which powerbank capacity for a 24hour autonomy?
- c) Would a voltage cutoff still be needed for a powerbank ?
- d) If that is possible, I was thinking of : hardwiring the ACC to an ACC fuse, and the "rest" to the powerbank. But I have no idea how to consider wiring ground in this "hybrid" case.
- e) I would place it all in the trunk. I would come replace every day the powerbank with a full one, charge the other one, etc.
- (Sorry to be such a noob and jump on the "Powerbanks are cheap, why not use them ?" )
Kind regards,
Montecristo.
