Voltage of Li-Poly batteries

[lifeisbetterwithketchup]

How fast does the voltage drop in a Li-Poly battery such as this?
It says that it's cutoff is 5.5v. Does anyone know how long it will stay above 6.3v to power one of these?

Each Li-poly cell is 3.7v. From what I've found, they usually drop 0.6v to their death.

Li-ion cells are 3.6v.

I cant load that link right now (blame my poor internet signal), but Im assuming its a 7.4v lithium battery.

if so, then 5.5v is like the absolute-minimum about-to-explode voltage, and I wouldn't recommend getting anywhere near it anyways. (thats 2.75 volts per cell)

usually most devices will shut off for self-preservation at about 3.0v per cell (6 volts).

so what Im saying is that the battery is pretty well fully dead at 6.3v; it will work just fine.

this is a pretty typical discharge curve:

Alright, thanks for the help. I really appreciate it.
