2-6 cell Smart Lithium Cell Balance Discharger This product features the charging and discharging of LI-PO cells. Normally, Battery charger will only consider the total voltage of the cells while they do not care whether each cell is balanced charged. For example: when the total voltage is 8.4V, if the cells are not balanced charged, one may have 4.1V while the other 4.3V. To make things worse, one with 4.0V while the other 4.4V. This affects the cell performance. This product is designed to solve the above problem. It allows cells to be balanced charged, that is, every cell is at the same voltage when they are fully The discharging feature of the product also helps the lithium cells which are stored for a long time. When the lithium cell is charged fully at 4.2V, it may swell due to fully charged but not in use. This affects the cell capacity and performance. Lithium cells are best stored at 3.8-3.9V. This product can charge the cells to the optimum Besides, cell voltages can be shown by the product, so that users may check the Functional keys and symbols are shown in the diagram. Connect the balance charger to the discharger in the corresponding plugs. There are 2~6 cells with 5 sets of pins. Only one set can be used each time. Caution: Do not use two or more sets of pins once. This will cause damage to the After inserting the cells, the discharger will show the voltage for individual cell. If “Err” is shown, it means that there is a cell which has a voltage lower than 2V, a faulty cell. The discharger will ignore this cell automatically. After showing the voltage, press “MODE” to enter the discharge menu, pressing once will enter the next stage, circulated display in 3 stages: they are “Balance Voltage Limit”, “Discharge VOL” and “Total Voltage” respectively. Adjust the value for discharge voltage using the “▲”“▼” keys. Press “Cancel” to return to the voltage interface after adjusting. Press “Balance” to start balancing job or “Discharge” to begin discharging. “Balance Voltage Limit” --- Balance discharging mode. Begin charging when cells are connected to the charger. Return to the voltage interface after setting the allowed balance voltage. Press “Balance” to start balancing. There will be a “←” pointing at the discharging cell. Two “=” will be shown on the right hand side of the display. The initial voltage is 3.3V, which means that it will undergo balancing only when the voltage is greater than 3.3V. Press “CANCEL” to If the cells are not cast off after balancing, the product will close automatically after 15 minutes. After the adjustment of the balancing process, all the cells will attain For 3~6 Cell, the lowest limit of the balancing voltage is 2.2V and the highest is 4.1V For 2 Cell, the lowest limit of the balancing voltage is 3.2V and the highest is 4.1V (When the total voltage for 2 Cell is lower than 6.04V, the discharge will close automatically in 5 seconds after showing the voltages.) Typical charger can be accompanied with the use of the balance discharger, some Charger can afford electric current which is greater than 6A. This facilitates the charging speed of lithium cells which have large capacity, beside, every cell can be charged to the same ideal voltage. It is speedy and more efficient than using the Charger alone. Using typical Balancing Charger would take a lot of time to charge cells, besides; due to the resistance in charger pins, the charging is limited to 3A. “Discharge Vol” --- Discharge mode. To be used when the cells are to be stored. Cell voltages are shown after cells are inserted. After setting the optimal voltage, press “Cancel” to return to the voltage interface. Press “:Discharge” to start discharging. A “←” will be pointing at the discharging cell. Two “/” will be shown on the right hand side of the display; it means that discharging is in progress. The initial voltage is 3.9V, which means that discharging process will only start when Press “CANCEL” to cancel discharging process. If the cells are not cast off after discharging, the discharger will close automatically after 15 minutes. If the cells are charged uniformly to 3.9V, it will be safe for storage. For 3~6 Cell, the lowest limit of the discharging voltage is 3.5V and the highest is For 2 Cell, the lowest limit of the discharging voltage is 3.2V and the highest is 4.2V (When the total voltage for 2 Cell is lower than 6.04V, the discharge will close automatically in 5 seconds after showing the voltages.) (When using 4~6 cell for discharging, it is highly recommended to use a fan to cool down the set up, this is to ensure that the LCD will not alter its colour under high temperature which affects the life of the set up) “Total Voltage” --- Total sum of current cell voltages. It enables users to check the Please ensure that the cells and the discharger are connected probably. When there is a failure, stop using the product and contact us.
