1. A method for providing balanced and individualized charging to each battery cell in a plurality of battery cells, the method comprising:

  • feeding a total charge current to a first power balancer, wherein the first power balancer regulates an effective charge current applied to a first battery cell of the plurality of battery cells;

    controlling the first power balancer using a microcontroller, wherein the microcontroller monitors a current charge level of the first battery cell; and

    using the microcontroller to vary a balancing current in the first power balancer such that a difference of the balancing current and the total charge current is applied to as the effective charge current to the first battery cell, wherein the effective charge current is relative to the current charge level of the first battery cell.
