Giá đỡ pin dự phòng cho Unistellar eVscope 2

Battery backpack that clips onto the arm of the Unistellar eVscope 2. Should work with other models if they have the same dimensions of the arm that the eVscope 2 has. 

This allows you to provide USB power to the scope that travels with the scope, so you don't risk a cable snag and breaking the USB power port. 

I designed it to work with this Anker battery pack:
