Watson Pro Cine High-Load V-Mount Battery

I have an Aputure 300d II, and this battery powers it at full power with no problem. I've only used it for an hour, but the battery didn't even go down one notch in that hour. I will buy another and I'm certain they will last all day.

These are compact and easy to grip. Maybe if you're powering a camera these would be fine but not lighting. I barely got 35 minutes running at 100% when the battery level meter hit 2. We've found when they reach 2 you better replace them soon. We've used them on our Genaray 18 Moon which requires 2 batteries maybe last 45 minutes. These were fully charged by the way with the Watson designated charging base.

These batteries are a luxury and a POWERHOUSE! Using these on the Genaray Radiance and will also use on massive LED panels that I often find on the sets I film. I am SUPER excited for the fact that I have unlocked one of the most important features of the Genaray Radiance AK-230 LED Monolight!! That's 230 watts of lighting that you can take it out on the field, and YET on a budget, instead of being limited to the other consumer level LED monolight products, with their standard non V-Mount batteries limited to 60 watts and the battery dies in 50 minutes. The Radiance, which I purchased directly from BH, its setup consists in professional V-Mount batteries, and will last a long tome on set, even at full blast whenever you need all the power you can get, still at a decent cost. Price Vs efficiency / performance: The same way you could get an aftermarket part for your car for a bit less cash, it's never as good as the OEM. With that said, the cost of this V-Mount battery model is designed for STAMINA, performance and high amperage, driving the Genaray Radiance already super bright at 50% power in excess of 2 hours and 47 minutes. Push it to 3 hours if you absolutely must but not recommended for any battery when it reaches the flashing 1 bar status. Even at this critical level, the battery still remains cool, unlike most batteries that will get very warm when depleted. If that's not enough, you can use the onboard 12V 10Ah D-Tap and the 5V 1Ah USB power jacks, all at the same time while even using g the V-Mount terminal! Weight: these massive batteries weigh nothing! 2.2 pounds each. Charging time: BOTH batteries charged on the charger I recommended below here, it takes only 4 hours and 20 minutes to charge TWO of these massive bricks. That's almost the time it takes to charge a Canon 1DX set of 2 batteries which they are large for a DSLR, but are tiny and minuscule comparing to a V-mount battery of this power. The suggested charger for this battery also comes with a 4 pin XLR DC jack in the front of the charger if you choose to purchase the Watson Pro Dual Position Li-Ion Battery Charger (V-Mount) #WACVM2E or Mfr#C-VM-2E As they say...'Buy once, cry once'. This is my philosophy every time I purchase gear. Yes, they cost a bit more but you'll be happy you did, instead of getting something else for less but also half of the performance, having to swap batteries more often and worry about batteries dying during an important take on the field. Every piece of gear I get / own, I test them rigorously before taking it on a shoot, especially events that I can't re shoot. With that said, I approve these batteries and sign at the bottom. No stress, no power worries. That to me is money. From cameras to lighting, from batteries to gimbals, if I can't afford the item I want, I wait until I can and make the purchase that I know I'll be happy with.
