Seriously, just grab the SmallRig DMW-BLK22 USB-C Rechargeable Camera Battery! They're amazing, super reliable, and havent given me any errors yet. Total lifesaver for the price, love it!

I have been shooting on the S5II since launch and that 4K60 definitely eats power compared to the older bodies. I've tried a few different setups to stay powered up without breaking the bank and honestly I am very satisfied with how some of these third party options are holding up. You dont need to drop eighty bucks per battery for the official ones if you pick the right brands.

• SmallRig DMW-BLK22 USB-C Rechargeable Camera Battery: This is my top pick. It works well and the built-in USB-C port means I dont even need to carry a separate cradle. No errors on my firmware so far.
• Neewer DMW-BLK22 Replacement Battery 2-Pack with USB Charger: I have no complaints with these for the price. They are super affordable and the included dual charger is small enough to toss in a side pocket.
• Wasabi Power DMW-BLK22 2-Pack and Dual Charger: These are what you mentioned... they are decent but I have noticed they can get a little warm during long 4K takes compared to the SmallRig ones. Personally, I would grab two of the SmallRig cells. They feel the most robust and being able to charge them with my phone cable is a huge win. I have done several long shoots in hot weather and they havent let me down yet. Definitely stay away from the super generic unbranded stuff tho.

Honestly, be careful with those cheap generic bundles. Ive had issues with the really low-end ones where the S5II just refuses to boot or gives that annoying non-genuine warning mid-shoot. Its super frustrating when youre trying to film. If youre on a strict 100 buck budget, stay away from the absolute bottom of the barrel stuff. It just isnt worth the stress. Unfortunately, the S5II draws way more power for the phase detect AF and the internal fan, so cheaper cells sometimes sag under the load and trigger those errors. Heres what I actually trust:

• Watson DMW-BLK22 Li-Ion Battery Pack is usually more stable and communicates way better with the Lumix firmware.
• Neewer DMW-BLK22 Replacement Battery 2-Pack with LCD Charger is decent for backup, though honestly, the capacity feels a bit lower than advertised. Just keep in mind that third-party stuff is always a gamble with Panasonic firmware updates. If you can find a used Panasonic DMW-BLK22 Lithium-Ion Battery for under fifty, grab it. Nothing beats the reliability of the original cells when youre doing 4K60, even if the price is a total rip-off.

> I heard third-party cells might trigger firmware errors now? Building on the earlier suggestion, I'm usually really paranoid about that kind of thing. When I first got my S5II, I spent ages reading forums because I was terrified of a cheap battery causing a glitch or worse during a shoot. I ended up picking up the SmallRig DMW-BLK22 USB-C Rechargeable Camera Battery and honestly, I'm super satisfied with it. I used it for a long weekend trip recently and it worked perfectly without any weird firmware errors popping up. They cost about $40, so you could grab a couple and stay under your $100 budget easily. The best part is the built-in USB-C port... I just used my phone charger to top it off while we were driving. It feels way safer than the really cheap unbranded stuff, and I have no complaints so far. It just works well.

Ugh, tell me about it. The power draw on the S5II is just on another level compared to the original S5. Honestly, it reminds me of when I was still shooting on Sony gear years ago before switching over to Lumix. I had this exact same headache during a destination wedding in Mexico. I tried to save a few bucks by mixing a bunch of different brands to see which ones would last through the ceremony and it was a complete disaster. My second shooter and I spent more time swapping cells and swearing at the chargers than actually framing shots. One brand would say 50% then just die, and the other would cause the camera to behave super weirdly for no reason. It turned into this whole ordeal where we were literally hunting for wall outlets in the middle of a reception while the cake was being cut. Its soul-crushing when you realize your gear is working against you because of a power mismatch. I still get phantom anxiety whenever I see a low battery icon blinking tho... just brings back all those bad memories.
