Could you build this?
No Designing and building physical battery hardware requires materials science, chemical engineering, physical prototyping, and laboratory safety equipment.
What it would actually take: Requires electrochemistry expertise, cell chemistry selection, cathode/anode formulation, battery management system (BMS) PCB hardware design and firmware, as well as physical laboratory facilities for cell assembly, cycler testing, and thermal safety validation.

Same idea, different domain
Nobody's really built a hardware & robotics tool for Horizontal yet.
