EG4-LL (48V, 100AH with display) built-in current limiting resistor

Each EG4-LL battery (48V, 100AH with display) has a built-in current limiting resistor and I want to know when that resistor switches-in to limit the in-rush current to the inverter, and switches-out. Each EG4-LL has a separate switch for its BMS/display and a circuit breaker. Is it correct to assume that I need to close its circuit breaker first and then turn on its BMS/display switch? I am assuming when the BMS is energized, it will have the current limiting resistor in the circuit and a few seconds later, it will switch out that resistor, otherwise it will not make sense, if I turn on the BMS/display first and then close the breaker second (with respect to in-rush). Thanks
 
I see your other thread which lead to this thread
