The Whisper controller is equipped with latest PWM (Pulse width modulation) technology to slowly lower the charging energy applied to the batteries as the batteries get closer to fully charged. This topology allows the batteries to be more uniformly charged with less stress on the battery, extending battery life. It also keeps the batteries in a fully charged state by adjusting pulse width (called float mode)
