UK ANO 2016 v PFAW/PFCO

" mass of more than 7kg excluding its fuel"

So does batteries count as fuel? Ie SUAV weight is over 7kg with batteries but under without batteries, is it still classed as 7-20kg or sub on the assumption that electricity is technically fuel?
 
Yes batteries = fuel so the MTOM is the weight including the battery(ies). The UAV must be under 7kg with battery(ies) and payload (camera) fitted.
