Hi Guys!
I installed the BMV 712 last year. It's primary purpose is to monitor coach batteries. I also have it wired to monitor the starting battery. I seem to recall that it could actually charge the starting battery as well when it dropped below a certain value although it was a low-amp charge, which is fine.
I can't seem to find any documentation on this. Last year I was sure I saw a wiring diagram from Victron for implementing this but can't seen to find *anything* related to documenting this feature. If anyone can point me to a link or in the right direction I'd appreciate it.
