Hi Rick1008, we are an Authorized DJI Agras Dealer. Feel free to email us at [email protected] with any questions.
We have not experienced any difficulties switching from the 16L to the 20L tank other than battery life. We did some test flights with the 20L tank with a T16 battery. There was a larger draw on the battery flying the 20L tank. We have some T20 batteries inbound which will fix this.
