I just lost a battery to somebody I was helping out.  Their battery's were dead so I used one of mine to power on his craft and after I finished up and got the guy flying again... we both forgot that my battery was in his craft... and I highly doubt when he does realize it that he will return the battery, so my question is as follows..

My Phantom 3 Advanced is on 1.6 when I buy a new battery do I just go straight to firmware 1.6 on the SD card or do I need to update the battery 1.4 to 1.5 to 1.6?
