25 Jun 2022: More lessons learned--please make sure and read the entire thread!
Goal: Use what I have already in the truck to charge or maintain my batteries while towing to the maximum extent possible without expending mega $$. That means the available amperage is 40A (through upfitter switch #5).
Note that the current 7-pin connector only provides 9A of 12vDC. (I've measured it using the BMV-712.)
Below is my system as it still is today:
Here's what I'm planning:
These are what I'm considering using to install the system:
The issue that has me perplexed is how to limit what the Battle Borns will draw through the Victron should they be discharged enough that the charger goes into BULK mode. When connected to shore power the batteries can pull more than 100A (of 12vDC). That's way too much for the system I've configured.
What I *think* I need to do is change the highlighted CHARGER setting in my Victron Multiplex through their software VE Configure. A setting of 39A should do it. I've sent an email off to AMSolar's engineer asking for confirmation. I'll report back when I get an answer. (The obvious downside is my batteries will charge slower on shore power, but as long as that doesn't hurt the batteries it is not a major issue.)
If you have any thoughts or recommendations I'd be very glad to read them.

P.S. I'm sure I haven't figured this out completely yet. Research, research, research...
