That's interesting. Royal Mail back in the day wouldn't let you post anything that had a battery inside, even if connected and non-removeable. For years I've been lying and saying "it's a box of minidiscs"...![]()
haha!
I generally always say its a camera or phone case etc!
Saying that, I sent some 4s LiPro RC batteries via Hermes (I know I know, but I was taking a punt and didnt care if they got lost....) and they got to their destination without issue...... just seems to be hit and miss! Post and keep fingers crossed!
