Ring Video Doorbell 2 hardwired question

I have a ring video doorbell 2 and would like to know how to remove hardwire chime but still have it charge the ring battery. The hardwire chime in my house sucks. I only had one lighted doorbell switch before replacing it with ring video doorbell 2. I never had a rear door button. So I just want to remove mechanical chime from circuit but still have ring battery charged. I'm concerned about the possibility of damaging ring device if I just remove chime. Also I'm just going to have doorbell ring handled by two echo shows and a Toshiba Fire TV.
