Hello, at my school a parent anonymously donated a P2 vision+ to our robotics team, and since no one used it or opened it our coach gave it to me when I asked him about it. The issue is that it didn't come with a battery charger and I can't charge the batteries. I looked on amazon and found a charger there but it was $80 and I didn't want to waste so much money on that. I also contacted DJI directly but they said they couldn't help me. So is there any way that I would be able to find the connector for the battery online at a reasonable price or is there any other method to charge the battery?
