How much run time did you get with

Battery is only 8 dollars not bad at all!
I just ordered that one today - so we'll see!
The SCUD "Hobbit" arrived - nice aluminum case - basically a cell phone battery in a case.
I topped off the charge - (seemed partially charged, didnt take long.)
I ran 4 channels @ 44/24 w/2 phantom on - well over 3 hours...but made the mistake of starting this test too late - and fell asleep!
So - I'll check the last file length - my internals were about half - so it couldn't have run too long on those.
Recharging now - I'll repeat the runtime experiment with this, more proper, charge cycle.
The one drawback on this battery is it has a power button. - So you'd have to be careful digging around in your bag.
That said - the button is stiff and requires a solid poke - and its somewhat protected by the USB output cable.
(but something to look out for when shopping for these batteries)
