I'm using a Powerbox Gemini system  Quite simply the best system I have seen or used. It is a total dual redundancy system, so everything is duplicated, and it uses 2 batteries. Once powered up, even if you unplug the switch it remains on 
It's fairly expensive, but so is my heli, so I think it's worth every penny.
