SMALLRIG10500mAh Replacement USB-C Battery for Sony NP-F970, PD 36W Fast Charging, 3.5H Fully Charged, for Sony FX3/A7 IV/A7S III, for Canon R5/R6, for Nikon Z8, Power Supply for LED Light, Monitor

My first review was not very positive. The battery only stayed charged for about 3 hours, and it took over 24 hours to charge it back up. I did have a little chat with Small Rig, and we agreed that if they sent me a new one, I would give it another try.I have been a big fan of Small Rig for years, and when I saw that they released this battery, I was really excited to get it. Since I have added a few things to my rig, I felt I needed a battery like this.Well, it paid off. The battery powered my monitor and my remote focus wheel while lasting the entire day of shooting, which was 9 hours. The recharge took only 3-4 hours.

Edit: Updated as the replacement unit had no issues. Same pluses as before - nice to have a battery read out as a percentage, which lets you know better how much you have left instead of just 4-5 pips. Smallrig construction makes up most of the connectors/adapters in our shop, so it's nice to have an option to go to reliably for battery as well.Customer service is responsive so definitely a good experience.I've ordered two of these. The first one was great - it's super convenient to have the battery read out as a percentage, and the field life is good. USB-C is also a quality of life feature that's worth paying for.The problem is QC. My second is permanently stuck at a maxiumum of 95%. It isn't a reduced capacity issue, and both are new (not used/renewed). Unsure what the issue is, and Smallrig requires the user to pay for shipping both ways on warranties and repairs.Your mileage may vary, but wanted to highlight this for everyone else, as it's certainly not ideal. Losing 5% off the top isn't a deal breaker, but other folks might have worse luck - with having to pay for both ways on shipping, you're kinda left holding the bag.

Purchased to go with my Shinobi monitor. It weighs as much as the monitor, lol. But I love it. Charged quickly, and I shot for two hours straight and never had to worry about losing power. I think it was at 80% when I was finished. I love that it came in colors other than black. On a multicam shoot I can distinguish my batteries at a glance.

Great long lasting batteries in my opinion. Best feature is knowing what the status on remaining battery life is through the touch function.

Works as described. SmallRig makes quality products.

Super handy battery pack for my gear! Highly recommended.

Love this battery! A little pricier than similar batteries but it’s very convenient to be able to charge with a usb c cable and also charge other devices. SMALLRIG has always been pretty reliable in my experience so in spite of the price I still give it 5 stars for all of the convenient features.

This battery makes my camera rig!Mounts on my external monitor then usbC to my canon r5c for 8k.Runs monitor and camera for over an hour!Worth every penny ! Good job Smallrig!
