FXLION - Shockproof 300Wh V-Mount battery 18A, 4xD-tap

Because the battery cells inside the case had to be designed very compactly, it's even more robust than the original Square battery series. We've done a lot of testing - dropping the battery from a metre to six metres, throwing it down the driveway and so on, and the battery is still in its original working condition. The rubber corners offer even more support, bouncing off the floor and absorbing some of the gravitational forces that occur when you fall. So if you accidentally drop the battery on the tray, don't worry! 

With 4 D-TAP outputs (which also act as inputs), you can power most of your cameras from a single battery without using splitters. The batteries have a USB C output and input.
