Major changes are:
- Better Battery Access & Storage: by taking away the bottom coverage slightly, users can more easily (dis-) connect a battery for charging.
- Sturdier Body: By improving tolerances, wall thickness and locking mechanisms, the cover is now much stronger.
- Better Usability with Baseball Caps: Through a re-design of the bottom clip, the system can now be used with baseball caps and headbands more easily and reliably.
