Smart bms power source

Hi

I have a smart bms I purchased with my LifePo4 smart batteries. I am not in a position where I can easily return it so need to use it.
my dilemma hangs in the fact that I won’t be using the main poles as intended, should I provide power here (input pole) in the belief that it also provides the power for the unit to function? There are no other ve+ inputs on it so I assume this is a fair place to start.

Do you mean the Smart BMS CL 12/100?

This take it's supply power from the alternator/starter battery.

I also think this is a bad design.

So placing a 12v supply in the input from alternator pole will provide the unit with power and allow it to function?
