Voltage Draw

[Scuba-Doo]

Something has been drawing on my battery overnight. Walked by the RHO tonight and noticed this. The usb light is on after engine off, doors locked and key put away in a faraday box. Im not sure what the draw is on something this small but wondering if anyone else is seeing this? 1st pic is when all lights come on and the second is thru the window when dash goes off.

Mine does the same thing but I haven’t had any issues with the battery yet. It’s probably normal. Fingers crossed though because I’ve only had it for three days.

Mine are for sure not lit up once the truck fully shuts off (or when I lock with key fob) ... in fact I think that a complaint for a few guys - wanting USB-C power to charge a phone without having to put the truck in run-mode. Interesting ... wonder if they are just lit up, or if they are powered to charge something too.

Same thing, as in, always illuminated? Have you tested your bed power plug to ensure it's not active too? Vampire hunting is such a pain in the ass, but hopefully you can find the culprit, or send to Dealer and roll that big die

It stays on for a while, doesn’t seem to be on permanently. I’ll need to see how long it takes to go off…

It would be nice if it did actually stay on for a half hour or so so you could charge when not running.

If you put your truck on a battery tender with an amperage meter - how much does it draw when the truck power latches? (goes to sleep) I'll test mine.

I just went and checked again. I know it’s been on for over 4 hours but it’s off now. I dont know if it had something to do with me charging the batteries or not. Once I reached 100% SOC it was off.

I guess now I have a baseline to see what voltage is tomorrow morning.

My interior lights seem to stay on for the 30 or so seconds my Headlights do. (I think that's what mine are set at, never changed from default)

I have not had battery problems yet however I did notice my voltage dropping significantly when the engine shuts off at stop lights. Didn’t seem to affect anything but after the problems others have had I decided to get a NOCO Genius 5 to make sure they get a full charge. I did not expect to hook them up and see the main battery was less than 25% after driving it half the day though…

I just added a NOCO 5x2 charger under the hood. Velcro strapped it in front of the main battery. Ran the cord out of the front tow hook area and tuck it behind the bumper when not in use. Every few days just top everything off. I also swap out trucks often when towing so would be good to keep my EV-RHO charged. Haha
