SmallRig V Mount Battery VB99, 6700mAh 99Wh 14.8V Mini V-Mount Battery Support 65W PD USB-C Fast Charger, with D-TAP, USB-A, Dual DC Port, OLED Screen, for Camera, Camcorder, Monitor, Filmmaker - 3580

This battery is awesome. It’s sleek, gives an accurate battery reading, and seems to last a decent amount of time (w/ my a7SIII I shot a 1.5 hour music performance recording through my Ninja V and had 54% left). I think an under-appreciated aspect of this battery is it’s charge speed. I swear it charges 30% in about 10-15 mins, which is great for small breaks during shoots. Will definitely be getting another.

This is an amazing battery. It is intuitive to use, it gives you wattages, it is small and dense which means it takes up less space for the same battery life. All the Vmounts I have used previously needed their own v mount charger. this just takes USBC which is something that i did not expect I would love as much as I did. the usbC port makes this battery double as a large capacity powerbank and that has been so useful in shoots where I might need to edit on set and i can have the confidence that it can charge my laptop as well in a pinch. it displays its battery and you can charge the battery pack from usbc while supplying power to the rest of your gear which means that if you connect up everything and your powerbank is running out of battery, you can essentially use this battery pack as a mains power adapter while running a monitor, wireless follow focus, transmitter all off the same device.an intersting really small note, it seems to not fully stand up flat, if you put it on the table and push it, it rocks a little bit, so the bottom is not completely flat. just a strange design (could also be that the battery is expanding but i find it unlikely)

Hace poco grabé una boda desde la mañana hasta la noche, con una sola de estas baterías y llegando a mi casa aún tenía carga suficiente. Excelente durabilidad

**UPDATE MAY-31-2023**The same day I posted my original review complaining that the D-Tap socket pulled out, they contacted me directly and even though the old unit technically still functioned (despite being broken), they sent me a whole NEW battery of the exact same type for FREE and even paid for express shipping so that I would have it the next morning. Ive honestly treated this new battery harsher than the original one by far and it has held up fine. I definitely just had a defective unit. If you also have a defective one of any of their products, just reach out to them through here and they will definitely make it right. I have honestly never been the recipient of better customer service in my life. Big Smallrig fan from here on out.-----Original Review (March, 2023): I'm not rough with my camera equipment. If anything I'm too careful with it. I charge everything religiously. This thing barely ever needs charging, after a full day of shooting it has never dropped below 65% and that's from 100%, powering a Sony a7siii, Atomos Ninja V, a Ulanzi LED, and a Tascam DR-701D Audio Recorder all at once the entire time. It's speak, lightweight, the interface is crisp and detailed/informative, and the hardware feels very solid.Until it isn't. I never yanked out any D-Tap cables or jerked thing around, but one day last week just calmly removing a D-Tap (in this case the locking D-Tap for the Atomos Ninja V), the entire female socket inside the Sony 99 just sorta.. slipped out of the body of the battery. Theres no discernable way to open the battery to fix it, and I've repaired plenty of laptops so this type of thing isn't very foreign to me. Just not sure how to go about dealing with this now as the D-Tap was pretty vital to my work flow. I could "make do" but for this price, we aren't supposed to have to.Hopefully I can get a refund or at least have it replaced, but I'm not counting on it. Looks like I'll be going back to Anton Bauer's.

Initially, I thought the SmallRig V Mount Battery VB99 had completely stopped working, as it wouldn't power on or charge. However, I discovered that it has a self-protection feature that reset itself overnight. This is a fantastic safety measure that ensures the longevity of the battery. Now, it's working perfectly and efficiently powers all my gear. Highly recommend!
