i have my extension tubes coming from yihi. i have the latest firmware in my devices. does anyone know if there is anything else i must do besides screw on the extension tube and add 2 batteries? will it recognize 2 batteries are attached and go up to 120 watts or is there some other method for unlocking the board to reach the highest wattage? sorry for the ignorance, i just don't wish to fry anything and there doesn't seem to be anything written about it anywhere on the yihi site. appreciate the help....
I had a tube from another mod installed (not very well) to try awhile back.. It went to 120 watts just by adding the additional 18650 with no issues..
