For safety purposes, this charger is designed to automatically deliver 1C charge rate
to lithium batteries Example : LiPo cell of 1500mAh capacity : 1C = 1500mAh ( = 1.5A )
charge current.
CAUTION
The maximum voltage for LiIon is 4.1V per cell, LiPo is 4.2V per cell and LiFe is 3.7V
per cell. Therefore, it is extremely important to choose the correct battery type to be
charged, as each Lithium battery has the different voltage level. Otherwise, it may
cause very serious damage to the batteries and increase the risk of a fire !
