I think Lipos don't have "memory" in there cells. How would it shorten the life? I might be wrong though.
I dunno?.. but I've read somewhere that discharging it at for example... @ 50 Amps life cycle would be shorter than @ 30 Amp discharge.... so I just assume that charging it faster would shorten the life cycle... but then again, I'm not really sure..
Yeah, after looking at the 610i and the 1210i, I've decided on getting the 1210i. The 500w charging is neat, but also dumb. :) You can't charge a 12S brick with it, only 2 6S packs. Since I'm wanting to make the move to higher voltages, the cell count is more important to me.
If anyone wants to move their 1210i, I might be interested.....
