The Futaba manual states this as a way to discharge.
I'm going with the Triton the only problem I can see with this unit if ASAT is talking about the Electricfly unit is that it needs a 12volt power supply to power it off 110v at home and this runs another $90. Is this the unit or is one made with it's own supply. I like the idea of being able to use it at the field to charge batteries but the added $90 makes it too expensive. Any other alternatives. Usually you won't need to charge TX and RX batteries in the field unless your competing at an event anyway.
