This is a full redesign of a backshell for the Skydrop vario with extended battery.

Improvements over the original (early model) design:

• USB connector is usable with ordinary USB micro cables
• Large flat back-plane (if you use velcro or other adhesive mounts on the back)
• Mounting lugs for 20mm and 40mm straps or rubber bands
• Tiny weight saving
• Fits broader range of replacement batteries
