Bear with my guys I'm learning as I go, thanks for the continued advice really appreciate it
I know I should just use the 1/0 awg everywhere but since I want to do this modular battery this is my guage dilemma with wiring up.
I want them to be easily separate-able by unplugging XT90 connectors (which apparently are rated for 90amp cont. which is the peak in my system) for when I need to balance charge, and for normal use.
I would think that 6awg on the first level connecting two of the 5s10p packs together creating 37v would be okay? Perhaps I should just remove the last series adaptor and 6awg and create my own 1/0 series harness (connecting the two 37v packs together). I could then still keep the extra series connector for bulk charging purposes?
Series
I have them plugged together in series when inside ebike using these adaptors and 6awg. Each group of 5s10p would be 18.5v. LG MJ1 cells are 10a cont each so x10 = 100a?



Parallel
I have them plugged together in parallel these adaptors and 6awg. for balance charging (bottom set of adaptors would need some wire to connect them since its a tight fit). Since the 1/0 wont fit into XT90 I could change guages using these terminals

And then..
Then use these big Anderson SB120 plugs for continuing 1/0 to the main contactor, then controller etc..
