Description

Not tested yet This design improment came from the following video: https://youtu.be/9YwErplHps8

The improvemtns that I made:

  1. Different battery holder: A. So the battaris will snap in and will not fall off. B. The battery is not in a case, so better air flow. C. The holders can dissapate the battery heat to the PCB.
  2. Large ground plane to cool the battery.
  3. Small jumpers so the PCB can be anything from 2S-7S
  4. M3 holes to be used with brass spacers.
  5. Smaller overall PCB.
  6. Some other improments.
