I came across this interesting intelligent charger for the Mavic batteries.
DJI Mavic Pro Drone Accessories Portable Intelligent Charger Charging Board
One thing I noticed was that they use battery connectors that are slightly different than what you get from dji. The contacts look to be more squarish - can't tell if they are the same thickness. If they did happen to be thicker, then there is the possibility that using this charger will spread the battery's contacts and make the connection to the Mavic be compromised. I think this is a good example where using a third party product could void a warranty.
