Buddy, Indeed two resistors of 0.002 Ohms in parallel act as one 0.001 Ohm resistor. Your busbar reading sounds rather high - if you need to be able to deliver 500Amp then the busbar alone will drop more than one volt...

Is the correct resistance for both now 1m ohm? I am working with my new Orion BMS and I can compensate for the busbars in the program. It is reading 3.71 m ohms per connection which is two batteries in parallel. So is my real resistance 2 m ohm? 4m ohms or 1m ohms is my query. I believe it is like any other two resisters in parallel and my new resistance is 1m ohm per set. Which means my busbars are contributing 2.71m ohms. Thanks in advance for any help.
