Hello
@Outbacknomad, hello everyone,
thanks a lot
@Outbacknomad for your suggestion... It's a great alternative, and I would have definitely tried this setup if I had a bigger car (sadly there is no outback around here
)or not fixed myself some budget constraints.
**EDIT for
@Outbacknomad : sorry missed your message above, your solution is not expensive actually ! **
So I tried some more and I have reached a standstill.
1) Powerbank autonomy (Baseus BS-30KP365, 30 Ah 65W max) :
- with the A800S hardwired and running in "normal" mode, screen on (12V, observed load current between 0.3-0.5A)*
- the battery went from 93% to 60% in 7 and half hours.
- (the battery is not passthrough)
2) Powerbank + Trigger + Diode + Car Battery setup (see below) :
- I tried the setup and the diode (1N5818) immediately started smoking. No need to be an electronics expert to notice there is something wrong there. Result : fail
(Thanks a lot
@Nigel for having spared the time to look into it).
3) What's next :
- Based on the initial objective, I have two solutions :
a) Set-up an isolator + AUX battery as
@kamkar mentionned. Robust and proven solution. The issue being that if I let the car stay parked for some time, it is less of an "easy plug and play" solution.
b) Connect the Hardwire kit to both the car battery, AND the power bank via the triggerboard. But add a binary switch (0- HWK to battery : 1 -HWK to triggerboard+powerbank) and manually switch to 0 before starting the car and driving, switch to 1 when parking the car.
- I think that for my case, I will go with the b) option because its more plug and play friendly. I could always change to a) later if the context compells it.
As always, thank you guys for your time, and for any suggestion or alternative you may have.
Cheers,
M.
