Operation Manual of JABO-4100
Microcomputer Controlled Smart Charger
JABO-4100 Microcomputer Control Smart Charger has adopted the most advanced technology of MCU controlled closed loop current feedback balance charging for Li-Poly battery pack. With intelligent applications, designed and programmed by professional technologists, and the standardized micro-processor, closed loop feedback circuit was devised. Under the control of that, dynamic voltage of each cell can be clearly monitored on the LCD screen and appropriate current can be automatically adjusted according to voltage of each cell. Therefore, this will largely promote charging efficiency, extend the service life of battery pack and ensure the security while charging. Besides those functions, it also possesses the function of battery repair for over discharged battery, which ensures the full charge of each cell.
JABO-4100 Microcomputer controlled smart charger is capable of parallel (balance) charging 2-4 cells Li-Poly battery pack and series charging 1-9 cells Ni-MH battery pack. Manually selectable charge time, safety protective charge voltage, current and cell count. LCD screen indicates dynamic charge current, voltage of each cell and the pack voltage, which provides convenient, safe and reliable charge.

II Main Functional Features:
1.Free charge option of Li-Poly battery or Ni-MH battery:
The Smart Charger is capable of parallel charging Li-Poly battery pack and series charging Ni-MH battery pack.
2.Chargeing Time Control:
Charge time can be manually set. When the fixed time is reached, battery charging will terminate automatically. (Default setting is 3 hours)
3.Selection of Terminated Charge voltage:
Several types of terminated charge voltage can be chosen, 4.15V-4.25V, 0.01v one step. (Default setting is 4.20 V)
4.Charge Current Set:
The charger has several segments of charge current for choice, 500mA-4000mA, 100mA one step. (Default setting is 800mA)
5.Selection of cells count:
in Ni-MH mode, cell number is 1-9 (Default number is 6). In Li-Poly mode, the charger will sense the number of cells automatically.
6.Protection from battery reverse:
When battery pole is connected incorrectly, the charger cannot be available.
7.Automatically Battery Repair:
If an over discharged battery with exceedingly low voltage is charged with ordinary current, the battery may be unrepairablly damaged. The smart charger can automatically sense voltage of each cell when a Li-Poly battery pack is connected. If an over discharged battery (voltage is lower than 3V) is detected, the charger will intelligently charge the over discharged battery with smaller current. And when the voltage of the over discharged battery has reached 3V, the charge current will turn into ordinary current to continue charging it.
8.Identification of Bad Battery:
When charging a Li-Poly battery pack, if one cell or several cells are damaged, the smart charger will indicate BATTERY BAD and stop charging.
9.Indication of Full Charge:
When the battery voltage has reached the final safety protective charge voltage or the fixed charge time is over, the charger will automatically stop charging, give an alarm and show CHARGE OK signal on the LCD indicator.
10.Function of LCD Indication:
Set and indicate charge battery type, Li-Poly or Ni-MH.
Set and indicate charge time (Counting down)
Set and indicate charge voltage (4.15V-4.25V). The LCD indicator will show dynamic charging voltage of each Li-Poly battery and the Li-Poly battery pack, and the static voltage when full. For Ni-MH battery, the LCD indicator will show dynamic voltage of series charge and static voltage when full.
Set and indicate charge current (500mA-4000mA).
Set and indicate number of cells (2-4 cells Li-Poly battery, 1-9 cells Ni-MH battery)
Indicate REPAIR BATTERRY
Indicate CHARGE OK when the pack has been fully charged
Indicate BATTERY BAD when sense a bad battery and show the position and number of the bad batteries.
11.Buzzer Indicator:
Under such conditions: starting the charger, setting, identifying bad battery and full charge, buzzer indicator will sound.
