Just like with the K-70, it is pretty quick to change batteries. Taking a spare is always a good idea, and their being so small makes that easy. The larger battery for the KP's design would have necessitated a somewhat larger, heavier body, while the idea was for the lightest, most compact possible design in an advanced and pro-oriented body.
Like the rest of us KP owners, I think you'll find the more you use it and adjust to its design concept, the more you will find yourself appreciating this very unique and capable camera! I bought the battery grip based on general principle and my past experience with my K-5 then K-5 IIs. Not something I use regularly, but convenient in some instances and with some lenses. With it installed, the weight is around the same as the K-3, but the battery life is even longer and with lots of gripping surface. And you get some duplicate vertical controls for easier vertical use.
As for myself, at the larger end of medium hand size, I used the "no-grip" film bodies for years, so with small lenses the standard small grip is just fine, then I can change according to which larger lenses I might be using, just for general handling and balance.
