The stack-up chosen is the JLC04161H-7628 Stackup, off JLCPCB. The planes are as dictated: PWR-SIG/GND/PWR/GND-SIG.

Stitching Vias
Stitching vias are used to tie the power and ground planes. The stitching for the power planes allows the high current to distribute, allowing the board to handle such large amounts of current. The SaturnPCB tool was used to calculate how much amps each single via can carry, which atleast 50 vias were placed to handle 150A. Tieing the ground places with the stitching vias allows better heat dissipation.
