i personally hate the aesthetics of a Peli case.
So we did a remix of it and after many revisions by Pedro and Luuk, I finally had the ideal battery box, or at least the one I had envisioned.
v1
v2 (taller)
v3 (cut and added locking system as to access and service the bms if need be)
v4 (improved locking system and tolerances and better aesthetics. also removed all holes except xt90 and xt30)
