Function Introduction

1. Charge

Two channel can work independently and serve two intelligent batteries separately. Active, pre-charge, constant current and constant voltage are the stages of chargeing mode. The initial charging mode depends on the battery voltage, so active and pre-charge dont happen to every batteries.
