Only drawback is having to open case to swap. Any ideas on some kind of adapter/dongle/jury rig to hook up batteries externally?
The biggest problem is that LiIon batteries start ageing (and thus losing capacity) from the moment they're made. If you have three batteries, each with an estimated lifespan of two years, your three batteries will be good for two years.

That's why I don't buy spare LiIons anymore, but go for external batteries that mimick an AC charger.
