Could be..... Different battery tech though. Hugo uses two much larger lithium-ion batteries while Mojo uses one small Lithium-polymer battery yet Hugo and Mojo have the same specs. I know Li-po has a much better current rating ((C) the rate at which the current can be drawn from the battery) which is why it's used in high demanding RC applications, but less storage capacity than Li-ion.
This is a topic that really interests me but I am by no means a battery technician. Perhaps this is simply the way that Mojo can carry the same power spec as Hugo.
Well ESR is a big factor unless the ESR of the battery is limited by a circuit.
Anyway. . . . I love what I call "tunefulness" of the Mojo. The notes within a note, the micro harmonics.
