Power hardware, with the math checked.

Describe the battery pack, charger, or supply you need. Flux picks parts that fit your voltage and current, runs the calculations, checks the design, and hands you files ready to manufacture.

How Flux handles power

Brainstorm.

  • Pick the right architecture: linear, buck, boost, or a full charger.
  • Get a Project Spec with your voltage, current, and battery targets.
  • Set the enclosure size, mounting, and connector positions alongside the electronics.

Design.

  • Parts picked for current rating, efficiency, and availability.
  • Calculations and design rule checks run as Flux designs.
  • Enclosure, mounts, and heat sinking designed around the board in the same project.

Make it real.

  • Cost and lead time on every part before you order.
  • Manufacturing files and an enclosure, ready to send.
  • Stress-checked enclosure and mounts, with STEP files for your CAD tools.
