Took a Fuji X-E1 which I've sold to the PO yesterday. They were asking about batteries and I initially said that it did have a battery and it was separate. My story changed to it being a built in battery etc and the lady accepted it. I can't now remember whether I took the battery and put it in the Fuji box separately or whether I left it in the camera! Reading the above I should be fine if you are allowed 1 battery in the camera and 2 spares out of the camera I suppose. It was only going perhaps 4 miles across London! They also wanted £26 for it insured at upto £500 so ended up taking the risk at £100 cover at £13. Every time I go to the PO I get taken aback by some of the prices!
