This battery is sweet been using it on my r6 mark ii run and gun rig for a while now and it works great. Lasts about 8 hours while running my small rig fan to cool the r6! Isn’t to heavy balances a cannon 24-70 pretty evenly.

If you're on the fence, just buy it. I was hesitant to move over to a V-Mount system for the longest time. But man, these things changed my relationship to professional shoots. Over quick charge USB-C, it charges up increibly fast. On big shoot days, I can bring one of these guys fully charged, and never have to worry about battery life. The screen on the back helps a ton, especially when charging or trying to gauge how much battery life you have left. The build quality is sturdy and the look itself is sleek and unassuming. Super easy to use with a TON of ports for powering multiple devices at once. At full price, I still think these are absolutely worth it. But they're also on sale very often. Highly recommend

This battery has worked wonders for me and a great value for the money. While it works perfectly for my purposes, the battery drains a little faster than I expected but I'm not sure if my expectations are aligned with reality or not. But either way, it lasts a LONG time which makes how quickly it charges an even bigger plus. If I had a need to, I would buy another in a heartbeat.

If you’re looking to add extra weight and stability to your video rig, this V Mount Battery is a solid choice. I originally used this for my A7 III, using a cable from the battery’s USB A port, into the camera’s USB C port.Once I upgraded my A7 III to an A7S III, I quickly learned that the USB A port’s power was insufficient. Switching to the USB C port was all I needed to do. Now this battery has no issues powering the A7S III while shooting for hours.

This battery is a powerhouse! Compact design with plenty of mounting options. It keeps my camera, monitor, and other accessories running smoothly for hours. The digital readout is a nice touch, very convenient to monitor battery levels.

So, I bought this to power the SmallRig cooling fan...unfortunately, it doesn't do that, because when the fan goes into standby mode, the battery shuts off and won't come back on unless you manually do it. According to SmallRig, that is the normal. I'm not sure why they would say the fan is compatible with this battery then, but it is what it is.Apart from that, it functions and is built well! Obviously, I can use it to power/charge other things, so not a total loss. Just really wish it worked with the fan!

So convenient!!! I use this for multiple parts of my studio set-up when needed. It takes a little time to charge up to 100% but it holds that battery life a long time! It's heavy, so if you're using it for a part of the camera, I suggest an attachment piece for it. Love this battery, though. Worth it if you're considering it.

The amount of outputs this battery allows without any additional hardware is freaking awesome. This saved me hundreds of dollars and lbs of extra weight for my little fx3 rig. It also adds a nice-but-not-too-much amount of weight to the rear of the rig, keeping things balanced when held from the top handle.With this smallrig v-mount battery alone I can power my camera, monitor, audio receiver, HDMI transmitter AND still have a spare DC out port!I can get 3-6 hours of nonstop use on one of these V-mount batteries, depending on output load. But the best part is how freaking fast this thing can charge—if you bring a 65W charger to the party this baby can go from 30 to 80 in like 20 minutes, if even that long. It’s a Godsend on-set to come back from lunch with a fully charged battery!Cannot reccommend enough, especially paired with smallrig’s v-mount adapter plate (as shown, in fact 85% of the rig is smallrig hardware lol)
