NWPhoto, it was not to have a go at you, but those irritating so called "you tube" experts who spout a lot but know very little! In the short time I've had my X-T2 and used both types of battery, which are essentially the same thing, without any trouble. My understanding is that the original 126 batteries created heat when under heavy drain caused by using the video function, so the internal battery circuits have been rearranged/rewired to lessen the heat build up, as far as I can ascertain.
Would Fuji really not warn their customers of potential problems with their batteries, I don't think so!
As to SD cards I only use Sandisk or Lexar as I don't trust other makes! I also only buy the fastest that I can afford!
