What is CC and CV?

A CC power source will maintain current at a relatively constant level, regardless of fairly large changes in voltage, while a CV power source will maintain voltage at a relatively constant level, regardless of fairly large changes in current.

Which battery can charge faster and has better charge cycles?

Li-ion can be designed for a fast charge of 10-minutes or so but the specific energy of such a cell will be low. Ultra-fast charging only applies during the first charge phase. The charge current should be lowered after the battery reaches 70 percent state-of-charge (SoC).

Is Fast Charge bad for battery?
