Thanks for your input LeoS but from what I've read on here it seems the "INVALID BATTERY" issue is more a physical connection problem rather than a software problem??
I dreaded installing the 1.08 version, but I did. I went in to the app, powered up everything after the install. Got the "Invalid battery" warning. I did not fly it, but I did turn everything off and pulled the battery out and reinserted it. I gave it a little tap, like you would tap in a magizine in a gun, and did not have the warning again.
It seems that this is a reoccuring problem when updates are done. I guess I am going to have to hold my breath again when I fly it.

Someone please correct me if I'm wrong...
But my understanding is that: yes, the battery issue is mainly a hardware\design issue. There are 2 pairs of contact points between the battery and the phantom:
1. The first pair supplies the main power to Phantom.
2. The second pair connects the battery controller to the phantom. DJI uses this to 'authenticate' batteries, so users can only use original DJI branded batteries (until it's cracked and cloned anyway) and also use this communication line to pass on battery measurements and other information (# of cycles, etc) from the battery controller.
If you have problem with the first pair, then kaput. Bye bye. But this is very rare, practically unheard of.
Now the second pair is the problematic one. They may have designed it a little short (?) thus it can be dislodged unintentionally due to several reasons: vibrations, temperature changes, user error, etc.
If this pair gets disconnected, your Phantom still has power and it can still get rough measurement of the battery pack as a whole (not the individual cells), so the Phantom can still fly... BUT, on firmware v1.0, the default behaviour when this happens is to land. Even if your battery still has 99% in it and you're 1000' up.
I don't know how a firmware update can trigger 'invalid battery' issue. Can you point me to those posts? It may be a misdiagnosis.
