From the Braincube manual .........The controller will convert a wide input voltage range into the 5V supply the LEDs require, and can supply up to 3A of current.
The LED power supply is isolated from that of the receiver to protect your radio gear from the high current draw of the light modules.
All battery types are supported, including Lithium Polymer, with a voltage range of 6 - 42 volts (2-10S LiPo packs).
