Hello everyone, just recently purchased this item. So far, I love it! But I purchased an extra battery with it, and for some reason cannot get it to work with the aircraft. The DJI Go app says "Battery Signal Error" and lists it as 0% power, but the battery itself is fully charged. The original battery this came with has worked fine, not having any problems with it. I've been looking on the internet, but can't find what I need to do to fix thsi issue. Do I need to do another firmware update with this 2nd battery? I tried loading the files on the SD card like I did originally to update the firmware, but just cannot get this battery to work. Any help is greatly appreciated. Edit: bbfpv resolved this almost instantly (didn't have the battery plugged in all the way, I feel like an idiot) Thank you so much!
