I doubt that info is available but you might be able to check it yourself by hooking up a voltmeter to a cell and running some tests charging/discharging to see for yourself.
The problem with that is that any meter hooked up between the battery and the A-4 will affect how the A-4 reacts with and reads the battery.
I was just hoping that someone much more learned than me might have figured it out.
