Good question.Just purchased a new Ctek Multi US 7002 and was wondering where the best place to wire it would be?
Can it be wired under the the hood? Or would it have to wired directly to trunk in battery?
I'm thinking of picking this up: https://smartercharger.com/collections/accessories/products/ctek-comfort-indicator-panelGood question.
I was thinking about this myself.
I think that you could connect to the posts in the engine bay or to the battery in the trunk (either should work).
I am a little concerned about opening the hood frequently to connect to the maintainer because of the hood's large size and potential for misalignment/panel gaps.
So I will most likely connect the maintainer somewhere in the trunk (to the battery or someplace close by).
Do we know which of the circuits in the trunk it's okay to hook the cameras up to so that it doesn't drain them when the car is turned off and result in battery issues? I would still plan on hooking up a third-party battery between the camera and the car's battery, but I'm just wondering if anyone knows which ports are correct for this purpose as it seems like even mechanics / specialists are messing this up and causing warning messages to appear.
That's actually someone else's car on this forum but I did go through them as well and ended up going back to install a dedicated battery. Wiring directly to the BMW even with the power meter contorller it still tripped an error messages with the battery. Now I'm waiting for the dealer to get a new battery to swap mine out.But wait... Wasn't that @RRKnight's car? And didn't it still cause battery issues even though it was plugged into those ports? I guess if that's causing issues I'm not sure how you could avoid the problem...
So is the solution to tap into that 12v port as shown in that video using a relay but instead of hooking the relay directly up to the cameras, to hook it up to a battery, and then plug the battery into the cameras? It seems like something (this time, the battery) would still be drawing power from that circuit which, based on how the "smart" BMW battery operates, would still trigger the error message, would it not? Or did the other person on here do the same thing as you but with a battery and they haven't had any error messages yet? I guess I'm still not understanding how your install was even problematic to begin with if it was tapping into that circuit that doesn't pull power from the battery when the car is turned off...That's actually someone else's car on this forum but I did go through them as well and ended up going back to install a dedicated battery.

Yes but the difference is that it will only draw power from the car battery when the car is on to charge the separate battery and only uses the separate battery when the car is off. The battery error message is probably when the camera is drawing power from the car battery when it's off and making it weaker. The computer might think it's a faulty battery.So is the solution to tap into that 12v port as shown in that video using a relay but instead of hooking the relay directly up to the cameras, to hook it up to a battery, and then plug the battery into the cameras?

I guess my concern is how does the Blackvue (or other external) battery know not to draw on that same circuit when the car is powered off if the Blackvue cameras didnāt know not to? Is the Blackvue battery pack āsmarterā than their cameras in that regard? If not, Iām not understanding how the Blackvue battery pack wonāt cause the same issue.Yes but the difference is that it will only draw power from the car battery when the car is on to charge the separate battery and only uses the separate battery when the car is off.

I didn't do the install so I can't tell you how but I'm pretty sure you can YouTube it.I guess my concern is how does the Blackvue (or other external) battery know not to draw on that same circuit when the car is powered off if the Blackvue cameras didnāt know not to?
