Yeti Pro 4000 Alternator Connection Issue - Firmware: 1.7.7 - Charging but not shutting off
The Yeti Pro 4000 is not connecting properly to my vehicle for alternator charging via the High Power Port (HPP) Input. When connected it charges fine, but the connection is not shutting off when the vehicle turns off, or when the voltage drops below 11.8. ( When connected to the vehicle, I have waited 20+ minutes - when the vehicle is shut off - to see if the yeti switches the connection off, I have also measured the vehicle's battery voltage down to 11.5 volts, and the yeti still pulls from the battery in both circumstances.)
So there is currently no circumstance I've found where the yeti pro shuts off automatically when it is directly connected to my vehicle via the hpp high voltage port.
Note: I tried switching the vehicle connection to the low voltage port and the same thing described above happens.
For context: I have bypassed the Escape Remote Display HPP+ Power and Data Adapter Cable (Signal Splitter) and the Comms screen since the comms screen is not needed in my vehicle setup. I was told this is not where the voltage drop detection happens (it happens in the yeti itself) so it is fine to remove these components from the setup and still have the alternator charging/ auto-shutoff work.
Also, i was told to remove the hpp+ 3 in 1 parallel combiner from the setup because with the new firmware update it would not work with the vehicle connection anymore. And the Link hardware that is suggested for older yeti models is not suggested for the yeti pro 4000.
So, currently I have no way to shut off the yeti pro from charging off of my vehicle's battery. Everything else on the yeti pro seems to be working perfectly besides this.
Resets I've tried: Factory reset; unplugged all ports from yeti and shut off (wait 30 sec.); Soft reset holding pair button and light button for 10 seconds; app based restart.
Any recommendation would be appreciated.
(Current firmware 1.7.7, Date: Feb 2025)

That sucks - maybe an external inline low voltage cutoff? I wonder what's wrong with your unit and/or install.

@martinjave yea I was recommended an irhapsody 120A 12V continuous duty relay to try by another member, so I'll see if that does the trick to automatically shut off the connection without having to rely on the yeti. It was also suggested that the standard 10awg wire that runs from the battery to the yeti is too long given the wire's gauge size, and it's causing a voltage drop that's below the Yeti's cutoff for charging. I'm going to attempt a beefier wire gauge to make the connection between the vehicle and the yeti and see if that can get the voltage in the proper range.
