The Power Expander EQ6 is Smart Fly's new power system that has the capability to work from 85cc to 140cc gas engines. It has two power inputs, supports eight receiver channels and provides one amp of clean regulated five-volt power to the receiver. Each receiver channel can drive three servos for a total of 24 outputs. Lithium batteries should be used with this unit. Power is supplied to the unit through the two Deans Ultra plug male connectors, (not included) . Each of the three servos on the six channels can be independently reversed and the center and two endpoints set. The power inputs are protected from each other in case of a dead cell or short. There is a 0.47 drop between the input and the regulator due to the input protection. It is highly recommended that you use two battery packs for redundancy and to provide extra current to the unit.
