I purchased the sunnylife 6-1 charger for mavic 2 off of amazon. I used it twice without any problems. It was staying nice and cool with 3 batteries and the remote charging. On my 3rd use, i heard a loud pop. Went to look at it, and 1 of the batteries was no longer charging. Removed that battery and there was another loud pop, followed by a puff of smoke. The who charger is now dead. This happened on Thursday, Amazon had a replacement at my house by yesterday. Im just not sure if I can trust this one though.
