I bought a Mavic Air for personal use about 24 months ago. I now need two new batteries, however, DJI informed me they no longer make them. wtf?! I cant find any in Australia from 3rd parties either. I was looking at purchasing the MATRICE M300 RTK for business use. With drone, camera and batteries weighing in at around $30k AUD, I want it to last. I am concerned that DJI's business plan is to force model redundancy after 2-3 years by ending the manufacture of critical components. Can anyone shed light on how DJI do business? Also, can anyone recommend a high-end drone manufacturer that provides better support through ongoing component availability?
