SMALLRIG 2400mAh Repalcement USB-C Battery for Sony NP-FZ100, for Sony A7R V, A7 IV, A7S III, FX3, FX30, A7R IV, A7R III, A7 III, A7C, A7C II, A7CR, A6700, ZV-E1, ZV-E10 II, 2.5H Fast Charging

Battery life seems equivalent or better than Sony & Neewer batteries. Doesn’t trip safety warnings on my A7RV & A7iii. Tremendous value. Charging speed is fine.

I previously had purchased a pair of SmallRig batteries that came with a USB charger block. I wanted to get another battery and opted for this one. I appreciate that it can be charged with my dual charger block, but also allows for direct USB charging while on the go. I also like having different colors because it helps me keep track of which I used when swapping out batteries during an event.

im mad i waited so long to get this. it holds a charge for as long as it says and now i dont need to switch as often

I'm afraid to upgrade to the next FW version, but for now, these work without the annoyingly timed nanny messages about non genuine batteries!

Just put this in my new A7RV. No warning.

Limited ability. I mistakenly thought that you could charge other batteries in the carrier…wrong simply charges the one battery. Ok if you want a spare battery. Wild recommend a charger that can recharge multiple batteries.

Pros: Battery registers correctly with the camera and it gives a (relatively) accurate battery gauge. Has good capacity too, seems to run down a little faster than the Sony originals but not dramatically so.Cons: charging speed via USB-C is a lie or I have a defective battery. One or the other must be true because it will only briefly draw 10W (5V @ 2A) before rapidly dropping to 5W at best (lowest level basic USB charging standards.). Actually charges faster when left in the camera and charged via the A7RIII's USB-C port where it will draw 7W, just like the official Sony NP-FZ100 batteries.
