Ultimately it just depends on when the big battery will charge the small battery. In some cases such as with my Mach E, I’ve been told it will only charge the 12v while the car is on. So if you’re running a dash cam when parked for a long time, it will kill the 12v. However other EVs will top off the 12v whenever it’s needed, even when the car is off. I THINK the EV9 and other E-GMP vehicles do, hence the orange light. So in theory you can just use the dash cam whenever, without killing the 12v. Eventually it would kill the big battery of course, but that would take like a year. So it’s practically infinite.
Yeah it definitely seems like YMMV on that one. Regarding the big battery charging the 12v battery, I've heard some people say that it can only do it like 10 times. After that, it stops doing it and I think it even issues a warning to the user about the unexpected power drain.
As far as I know, Tesla continuously tops off the 12V battery. I installed a Viofo A229 Pro 3-channel in my 2016 Model S and tapped into an always-on 12V line in the headliner and it has been working great with no battery issues.
On ICE cars is normal to have bigger 12V batteries as you need high peak current to start the engine multiple times. On the other hand, you do have EV's with inverters(Rivian,Cybertruck) and outlets in the back, not sure if those are tapping into the HV battery or they just have a larger 12V one....
I wish I knew all the answers. Never worked on a Rivian or Cybertruck. We do work on majority of EV,s on market. Porsche, Audi, VW, GM, Ford, Kia, Hyundai, Toyota, and more. Most EV, s have a small battery.
Off-topic, sorry. Which Pioneer system integrates with the Escort MAXCAM 360C? Is it the AVIC-8600NEX? Looking to get a double din GPS/CD/Stereo Deck for my Car. Nevermind, I see its AppleCarplay/Android Auto that connects to that detector. So I’m assuming the Garmin 86 Drivesmart would work as well?
Hybrids, like EVs, have a smaller 12v battery than an ICE vehicle, so if you’re running the dashcam while parked it will drain the 12v battery faster than in an ICE. Hybrids typically only charge the 12v battery when the car’s hybrid system is “on” (ready light is on so it can be driven). So you’d want to use a dashcam battery pack if you want the dashcam to run while parked. Now if you’re only running the dashcam while driving, you can connect it to an accessory switched circuit and then it won’t drain the battery at all unless you leave the car in accessory or ignition on/not ready mode.
@@ilovecatsandsynths9702this is why we always recommend dash cameras with a 3 hour parking mode timer option so you are limiting the wear and tear on the battery. But a lot of dash cameras do not have this timer option and will run your car battery down.
I have a two-channel BlackVue installed in my Tesla. No external dashcam battery is needed if you tap into a 12v circuit. When the 12v, or 15v (newer models), gets low, the vehicle will activate the DC to DC converter to charge the low-voltage battery.
