Characteristics: 1.Design in germany. And a chip controls the process: avoids mistake, ensures charge efficiently and accurately. 2.Adopt clipper-built aluminium casing which has better heat dissipation function. Different from traditional design, it does not use fan in order to reduce volume and weight. It is more convenient to be taken with. 3.It can suit various using environments through an adapter which has wide voltage range (12-18v dc) or car-charger connection. 4.Automatically detects 1-3 lithium cells battery packs, restores low voltage cells and displays the situations. 5.Automatically detects each batteryf+s voltage in the battery, balancing control charge, ensure the voltage keeping balance. 6.Led indicators with 3 colours. 100mm*70mm*25mm 160g
