The present disclosure provides a method for filtering in a cordless electrical device. The method may include coupling a filter network, a microcontroller and a plurality of battery cells having a cell voltage and a current. The method may further include operatively connecting at least one switched capacitor low-pass filter to the plurality of battery cells, the at least one switched capacitor low-pass filter configured to receive a signal from the filter network. The method may also include filtering the signal from the filter network, delivering a filtered signal input to an ADC and generating an output from the ADC.
