Is it possible to turn off the charge timer and simply use the mah setting? Reason I ask is that I have two 6500Mah 65C, 2S packs and of course these take quite a long time to charge since I can only charge at 5.0A.

So Right now I've upped the timer to 140 min...but they generally stop charging around the 100 mark (one goes closer to the 120 mark sometimes).
