Thanks!
Well, I was going to just switch it on and off manually through an isolator as I show in the video. But I'm going to remove that and add a 30 amp DC to DC charger to completely protect the rivian system.
I looked at those as well, they are very similar and very similar in price. But the one bonus I'll give to the EV sportline rmaxx, is the full length 13" wide, quarter inch thick skid plate that runs from front to back. It's a nice, smooth surface and nothing gets hung up on it.
I complained about it several times to rivian, and nothing ever changed. They just kept replacing the speaker.. I seem to get the correct charging voltage from the truck, so if it is the truck, I have no idea.... But considering the speaker can literally be sitting out on my shelf, and randomly...
I got it here:

But note that you do need to set it up to work on a lithium iron phosphate, 3s battery.
You do that by holding the test button until it goes into configuration mode, then press it again to cycle between lithium ion, lithium-Iron phosphate, and lead acid...
