Americas Dual battery option using the CTEK Smartpass 120

[Lars]

Why does the "Consumers" lug on the Smartpass 120 come with a warning label not to use it. The consumers lug on the CTEK Smartpass dual battery system is there to be used for accessories, such as refrigerators, camp lighting, radios or other electrical equipment you do not want to connect to the starting battery. Why did Ineos engineers chose to delete this function? The reason I opted for a dual battery system is because of this feature. Can we use it anyway without issues?

Philosophical system design choice. Run everything off starter batt. If it gets depleted then you have a backup to start the car and get it recharged again via the alternator.

There was also some talk about owners overloading the circuit.

I just run my accessories circuit from my aux battery terminals - wire gauge for 50 amp circuit, with 40 amp inline midi fuse.

I run all my accessories from the spare 60amp fuse in the fuse box connected to and adjacent to the main starter battery I’ve put in a small fuse box to fuse each accessory separately from this including power to my Alucab lifting roof conversion

Yes, it was a engineering design choice and there are work-arounds, but that doesn't answer the question...Why did they choose to delete the feature that allows accessories to be powered off the main/aux battery with built-in low battery cut-off and a continuous rating of 80A. It's a feature that was built into CTEC system they chose. Why not use it? Can we use it anyway? I guess the easy answer is that, once again, they thought we needed a parent in room to tell us no or we would use it improperly.
