Hi,
I would like to extend my car battery with some more power,
just to be safe,
sometimes I park for a very long time in a parking lot and then its necessary to have some extra power.
I had already some people who drove against my car without leaving any note ☹
I made up next scheme to provide my dashcam with power.
Is it logical or did I forget some things?
I’m a lot on the road, so the extension pack has time to recharge.
+/- 60h a month.
Idea:
When the car is running the dashcam need to be powered by the alternator and the extension pack needs to charge.
When the car isn’t running, the power first need to come from the extension pack
When the extension pack is drained/dropped under a certain voltage, the power needs to come from the car battery.
When the car battery dropped under a certain voltage, the dashcam needs to shut down.
When the car starts, everything has to work again (automatic voltage controllers)
Cost: +/- 70€
worktime: +/- 2h
Dashcam
VIOFO A119 V3
256GB
+/- 0.35Ah usage
= +/- 41h extension runtime
(7.2Ah *2/0.35Ah)
