Building a diy bank using BH's pre-built packs, 16 sets of 3 cells on 1 BMS. Making a 48v 300ah battery.
Trying to understand how much material/wire I need for each connection.
This is a mockup of my build. Currently planning on using doubled up 3/4" x 1/8" aluminum flat bar (from lowes) for the parallel sets. And connecting then using 1 bolt through both the positive and the negative for the series sets on the doubled up flat bar. Really trying to conserve space.
(RE concerns about shorts: I will be heat shrinking the alu bars entirely, and wrapping the bolts w/ electrical tape.
Pics to try and show better, cause I suck at explaining it:
this picture shows how i want to connect them in series. (above you can see how i change levels or sides)
Thank you.

Edit: I'll be using the Victron 48/3000VA 120v inverter. But I'm more interested in the general rules of how current flows through a series parallel build like I'm making than someone giving me the answer to my specific problem.
I would like help understanding the ampacity of the connections between the batteries, both parallel within the sets, and in series across the sets.
