With the SD card you have to push it so the card is actualy in the case about 2mm, if it wont lock is it in the right way, try inverting it, contacts inside camera.

To get the % reading its the last or 2nd last item on the menu CH will flash at the start of charging....They do get warm un plug it when it gets warm...Do a record untill it goes flat. let it cool then recharge, do it a few times and the battery should come up..

I just use it on the plane powered with the TX battery..
