The long story short is... you could be better off keeping "Batt-LIN" sensor disconnected to help prevent 11.xVolts drain-by-driving and engine ECO heatsoaks.
This is an experimental solution I have not tried.... I run "ALT-LIN" for the same reason.
FYI: Networking of R-SAM to ECU is marginal given the stock variable voltage.... besides ENGINE IS PROVEN TO RUN BETTER ON STABLE VOLTAGE.
The FRONT Battery LIN sensor runs back to REAR SAM to hop on CAN-B to run back to the FRONT CGW to talk to CAN-C ECU... This extra long loop serves its purpose: it's known to be reliably unstable for a long-long-long time.
What an awesome feature.

When I read this title, I yelled: Free ALT-LIN!
No stretching or crawling.

that's possible but when ECU is still in control of ALT... who knows exactly what ECU does with voltage -- It should hold it at x-Volts but then when ECU logic goes nuts then what?
There's a chance "BATT-LIN" can be as effective as "ALT-LIN" - Personally, I am all set with that.
"BATT-LIN" disables IC Display ... I need to see voltage displayed before I entrust my life to MB computers!! trusted voltage display

There's a chance "BATT-LIN" can equal "ALT-LIN": I am already all set.
