Well what can I say about this 12 Channel PowerSave receiver other then you would only buy one if you need it Cos is dam expensive lol.
The technology is brilliant it will sense the slightest voltage drop and transcend to the secondary battery pack without losing any performance of the control services and voltage drop.
The unit comes with three satellites left right and back also comes with temperature sender unit for the gas engine ie cylinder head temperature and voltage for battery pack as well as mah!
If voltage drops and transcend into the secondary battery pack you will notice the blue light on the receiver unit!
