Don't get the Li- Bim225, just the standard one, unless you plan on going lithium.
I have started the conversion of the high current DC panel to use a BIM device. This is what I have done so far:
I have the high current connections done. I am not sure about the SIG connection.
The BIM diagram shows 2 options:
Option 1 is to connect the SIG terminal to 12 volts with a (boost?) switch.
Option 2 is to connect the SIG terminal to ground with a (boost?) switch.
Do option 1 and 2 do the same thing? That is, cause the BIM to close like a boost relay. What is the purpose of the "IGN" terminal? I know that you are supposed to connect it to 12 volts controlled by the ignition switch. But what does IGN do?
