Complete vehicle harness, except engine. Rodent damage on a new 760i. Bags are full of the wiring/connectors that get pulled through firewall/trunk/rear openings to prevent damage.

Could you add lithium cells to that repellant and charge from the car battery? Using some 18650 batteries and a usb-c lithium charger hooked up to the accessories power would probably do the trick. Unless you use the car infrequently / power draw.
Lithium chargers are cheap as chips via aliexpress, just depends on the input voltage to the repellant device & how much power it draws. You could probably add an esp32 to that setup to report back if the charge is falling too low if you really wanted to get invested 😅.
Be careful with that. Have seen battery packs like that stuffed under dashes that have exploded.
Yeah, I think you can buy a repellent that hooks to the car battery, but I use the car somewhat infrequently sometimes and didn’t want to risk a parasitic draw on it.
