"over here" would be the UK presumably.
The new regs stipulate:
Your operator ID must be:
- visible without needing a special tool to remove or open part of your aircraft
- clear and in block capitals taller than 3mm
- secure and safe from damage
- on the main body of the aircraft
- easy to read when the aircraft is on the ground
Presumably having your ID underneath your battery would go against the spirit of being "easy to read when the aircraft is on the ground"?
FWIW I've also opted to go against the same rule and add it to my existing battery label. If worse comes to worse I could always shift the CAA no to the side and move the battery number.
