ElysiaVisuals is now offering a powerful 5V USB battery [2] kit that you can use to power our RamperPro timelapse controller [3]. We have tested several solutions and we have choosen this battery because it is powerful and affordable.
Our field tests show a 10 hour runtime with this battery; which should be enough for most shoots. You can always contact us if you need a solution for even long runtimes; there are many options possible because the RamperPro has 4 connectors that can be used to power the unit. You can even switch batteries while the RamperPro is running.
We have assembled a complete battery kit including a 1.8m micro USB cable that you need to power the RamperPro from this battery. We have also included a charger because most comparable batteries on the market are supplied without one!
