One of the most annoying tasks when dealing with production is taking care of power. At the end of each production day, you do the charging ritual every night to have a full bank of power for the next day. If you did not charge enough batteries, you’re basically screwed.
Drones need many batteries as each battery can only go for about 23 minutes on a 1:45 hours charge. This means that you need 5 batteries to keep a drone up in the air at all times. This is similar for cameras and heavier rigs. A lot of the weight goes toward big batteries that can last a long time. You need a big battery to power a camera, a monitor and some peripherals for a while, and you need a second (and third and fourth) batteries that can run for as long as it takes the first one to charge so you can cycle them.
Now Israeli startup StoreDot wants to change all that. The startup has a cell/charger technology that can charge a battery at 1400mAH / minute, and they aim to go to 1800mAh / minute by the productization of the battery next year.
This can drastically reduce the number and size of batteries you’d need and take the edge of not forgetting to charge all the batteries at night.
The company had a similar demo last year but it was big and cumbersome and now they are not only showing a faster product, they have managed to fit the form factor to a cell phone size.
P.S. Charging cameras (and smartphones) is small change, StoreDot wants to daisychain thousands of these cells to power electric cars as well.
