SWIT D-3004S 4-bay V-Mount charger charges four batteries simultaneously with a maximum power consumption of 200W. Charging voltage per channel: 15–20V, charging current up to 2A. A 4-segment LED indicator shows each channel’s charging status in real time.
If a charged battery will not be used for an extended period, it is recommended to optimize it by reducing the charge to about 50% to extend cell life. To do this, install the battery in channel 1 (CH-1) and press the “OPTIMIZE” button on the front panel of the charger. The cells will be brought to a 1A current level. Li-ion cells charge in two stages. Stage 1 is fast charging at the highest possible voltage, charging the battery at maximum speed. When the battery voltage reaches the set value, the charger switches to stage 2. Only the charging current changes; the voltage remains unchanged.
