SWIT Electronics D-3004S 4-Channel Simultaneous V-Mount Charger for Sony Ni-MH/Li-Ion Batteries

4-ch Simultaneous Charger f or V-mount batteries
With Max 200W power, the D-3004S can charge 4pcs V-mount camera batteries simultaneously. The charging output is DC15-20V, 2A each channel.

• V-mount battery charger
• 4-ch simultaneous charging
• 1-ch discharging
• 4-level LED charging indicators for each channel

LED Charging Indicators for Each Channel
The D-3004S has LED charging indicators on the front panel, display the real time capacity percentage of each channel when charging.

Discharging Function
When the batteries will not be used for a period of time, it is recommended that keep half capacity in the batteries before storage, to ensure a good condition of the cells and prolong the battery life. So the CH-1 channel of D-3004S can discharge the battery. Mount the battery on CH-1 and press "OPTIMIZE" button on the front panel, the battery will start to discharge at average 1A current.

Optimal Charging Curve
Li-ion charging follows a two-period approach. The first period is constant-current. The battery is charged at the maximum charging rate. When the battery reaches a specified set-point voltage, charging circuits switch to the second period: the constant-voltage period. The charging circuit will provide only enough current to maintain the voltage, to prevent the battery from over charging.

Multiple Safety Protection Design
SWIT charger can identify different chemical types of batteries and provide the correct charging program, to protect the batteries from over current, over charging, high temperature, etc.
