Connecting battery to Circuit breaker

I am unsure which way should i connect the battery(14S*P 18650)to the circuit breaker. The two options is: 1st straight from the circuit break to the positve terminal andnegative. pic 1 2nd From the circuit breaker to the middle and then to the postive and negative terminals pic 2.
