The battery extension kit consists of a portable battery pack (11,000 mAh) and a custom bag, which holds both the battery and the Pro Glasses 2 recording unit.
Connect the battery pack to the recording unit and extend your battery time up to six hours. Run longer studies in the field without worrying about your battery dying. When needed, you can enable battery extension easily and quickly continue your recording without compromising the participants' comfort.
If you already have a battery extension kit, you can also buy the custom bag separately.
