Sanyo ncr18650ga. And I want test sanyo 20700, this size fits as native battery box. Original battery plastic box size over 73mm x 43mm :) good for this
But I updated my drone with battery to 300, and i have not warning about updating battery. This is work too. I replaced 18650 and it work, not blocked.
