Some laptops have that feature.. E.g. my laptop has option "Extend battery cycle life", when that option is enabled it only charges battery up to 80%, which is ~4.05V/cell.Sounds counter to every PILA post on voltage I've ever read, and a worthy goal. Wish I could change a setting on my laptop to 4.1 or even 4.0v. I'm tired of killing expensive packs just from leaving it plugged in.
Good luck on your search!
It theoretically should be, yes. LG (D1 3000mAh / C2 2800mAh), Samsung (ICR18650-30A, ICR18650-28A) and Sanyo (UR18650ZTA, UR18650ZT) currently have 4.35V 3000mAh cells and 4.3V 2800mAh cells.I was wondering if using one of those new 4.35v battery at 4.2 was equivelent to using a 4.2v battery at 4.1?

Notice words "theoretically should be", re-think what I meant with that.Do you have any evidence of their longevity at lower voltages of these new type of cells?
Yes maybeWith 2ohm resistance I doubt Pila IBC would even start charging the cell. That high resistance might make it think it's a dead battery.
the end voltage is not always 4.2 v for example.
