Battery life with Flucard & wifi

I was wondering how users with K3's and the Flucard are finding battery life. My Flucard is on order and I'm curious how fast the wifi drains the battery. Will the grip and second battery be next?

The flucard draws at most about .5A as per the specs, which means its endurance is several hours even in the worst case scenario (the battery is 1.86Ah). After using it for about an hour, my battery meter was still at full, so I don't think it's a big power hog, as the power used by the wifi is probably offset by the fact that the camera's LCD doesn't need to be on in live view.

It's possible that the wifi has a stand-by mode, when the antenna is off but both devices still report as being connected.

Well I think when in Liveview with a SDM lens and flucard you will drain the battery pretty quick. So have a spare!

Looking at the spec sheet of Flucard, it consumes 1.7W max. The capacity of K3 battery is 14Wh. If you ignore the camera power consumption, it runs 8 hours. You should have actual result by some experiment.

In my experience using it for varying lengths of time it is not noticeable. Similar to a live view session. It uses battery but won't drain it quickly. I did a half to 3/4 hour session yesterday with a bunch of other shots, flash, autofocus, and the battery this morning still shows full charge.

I'd get a second battery out of general principles; you will run into times when a shot presents itself and your battery is dead.

Wow! This is great news for the use I am planning (tethered wild life shooting). I imagined the battery would drain a lot faster. Can't wait to get one!

(Incidentally, I am beginning to wonder if I earned myself a spot on Adams ignore list somehow: I asked this same question in two different threads he was active on and got no reply. Hmm. I haven't been annoying on purpose, for sure)

The only problem with shooting wildlife is the slow pace of shooting. It exposes then gets a thumbnail before you can take the next shot.

Right, that is a bit of a problem. Could still work for more "predictable" compositions, like pollinators with a macro lens... I wish we had hummingbirds in my part of the world.
