NEEWER DMW-BLK22 Replacement Battery and Charger Set, 2 Pack 2400 mAh Batteries and Type C Dual Channel USB Charger, Compatible with Panasonic Lumix DC-S5 DC-S5 II DC-S5 IIX GH5 II GH6 S5II S5M2 GH5M2

They're robust and they work perfectly. Loved the price.

I've been using this with my Limix S52x for over a year now, batters hold a good charge...not quite what OE does but it's usable. The charger works well.

These batteries perform very well for the money so far. Been using them the past 2 weeks. 2400mAh, so a bit more than the OEM 2200mAh. I tested recording 4k60 "i" codec, and it ran 45minutes, and had more juice left, but I swapped as a precaution. I also set up the camera in the menus, going thru a tutorial for 2hrs and 45minutes before the neewer battery was low. Very impressive. Of course, performance likely varies depending how demanding the format is.I'd guess a minimum of 1hr30mins active recording @4k30 in "i" codec. Possibly more, depending on settings.The dual charger takes about 6hrs to charge x2 totally depleted batteries. It's got a nice LED display that gives you that 25% increment visual.My batteries arrived about half-charged, so it gave a false impression that the charger charged x2 batteries in 3hrs, which isn't horrible. But, getting x2 quality batteries at this price, complaining about a tossed-in dual charger misses the point.The way to look at this kit from neewer: The panasonic OEM BLK22 battery is about $80, for ONE battery and nothing else. The neewer kit gives you x2 Batteries, that may even perform better. There's a little protective sleeve that slides over the contacts, which is nice. And it throws in a slow but dual charger. --all this for half the price of x1 OEM battery.I'd recommend getting a set of these, and then spending the money you saved towards something like a waston duo charger with the plates for the BLK22, so you can charge x2 batteries a bit quicker, but still have x3 batteries (x1 OEM that comes with the S5IIX, and x2 Neewer 2400mAh).It's great when something is more affordable and actually works! Thanks neewer!

These work great when I had to keep switching batteries because I took so many photos.

These work great but don't last as long as the original Lumix batteries.

Works perfectly. Sign of charging shows up on camera. Charger can charge original battery too. Great deal!

Muy buenas baterias

Just like the oem battery fit, but has about 90% battery life compared to OEM in my experience. Still worth the money. Great to use as backups on a long day shooting. I highly recommend.
