The smart cable from Furious FPV essentially lets you turn any battery with an XT60 connector into a way to power your DJI FPV goggles.  It supports 3-6S lipos and will output a constant 12V @2A to power your FPV Goggles.  Apart from being a voltage regulator, this smart cable is actually smart.  It has an OLED display to show your battery voltage, current, timer and temperature.  It also features a configurable alarm (time or voltage based) and also a low voltage cutoff to protect your battery if you forget to disconnect it.
