| Product DescriptionJB-1100 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 latest micro-processor, closed loop feedback circuit was specially and creatively 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. Unique circuit design of safety protection for battery reverse can detect and alarm by micro-processor when one cell or the battery pack is incorrectly connected. JB-1100 microcomputer controlled smart charger is capable of parallel (balance) charging for 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. A>Technical Specification:

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>Charge 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:
3 types of terminated charge voltage can be chosen, 4.15V, 4.25V, 4.35V (Default setting is 4.15V)
4>Charge Current Setting:
The charger has four segments of charge current for choice, 500ma, 700ma, 900ma, 1100ma. (Default setting is 500ma)
5>Selection of cells count:
In Li-Poly mode, cell number is 2~4 and in Ni-MH mode, cell number is 1~9. (For Li-Poly pack, if the number is not selected, the charger will sense the number of cells automatically).
6>Protection from battery reverse:
When battery pole is connected incorrectly, the charger will give an alarm. Meanwhile, the LCD indicator will show "BATTERY REVERSE" and the position of the reversed battery.
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 2.4V) 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 2.4V, 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 automatically give an alarm, 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 "CHAGE OK" on the LCD.

2)Charge under default settings:
Only for 2~4 cells Li-Poly battery pack (we take 3 cells of 11.1v for an example)
Connect the power source, adaptor and Li-Poly pack correctly, LCD screen will display as photo (sorry no photo available here). Press the start button, after a click sound, the charger starts working. Default setting of time is 3 hours and start counting down. Default settings of voltage is 4.15V, current is 500ma and number of cells is 3. During the process of charging, voltage and current of each cells and the total voltage of the battery pack will be shown by turning on the LCD screen as photo (xx). When one cell of the battery pack reaches the final voltage, the full cell with stop charging and charge current of it will be "0" on the LCD screen. Other cells continue charging until all cells reach the fixed voltage (4.15V), and the process of charging is finished. LCD screen will indicate full charge and the total voltage of the battery pack as photo (xx) Buzzer indicator will sound several times to remind the user of full charge.
3)Charge under manual settings
3-1 Li-Poly battery pack (parallel charging)
Connect the power source, adaptor and Li-Poly battery pack correctly according to the connection sketch map (we take 3 cells of 11.1v for an example). First press "Select" button, "Li" will be shown on the upper right corner of the screen. On the second line is "parallel". Further press of "Select" button is for charge time setting, which should be set according to battery capacity and charge current. Press "Enter" button to confirm setting. Another press of "Select" button is for charge voltage setting. Press "Set" button to set safety charge voltage. (Commonly set 4.15V or 4.25V, 4.35V is not recommended except when battery manufacturer specially marked). Press "Select" button again to set charge current, which is supposed to be set according to battery capacity. Press "Enter" button to confirm setting. Warmly recommendation: If you are not engaged, small current is suggested to efficiently extend battery service life. Having finished setting charge current, press "Select" button for the last item --- battery count, which should be set according to the number of cells connected. Press "Set" button to choose cell number and press "Enter" to confirm. (For parallel charged Li-Poly battery, the micro-processor can automatically sense and display cell count). So far, all function have been set. Then press "Start/Stop" button to start charging. The charger will work according to the parameter fixed.
3-2 Ni-MH battery pack (series charging)
Connect the power source, adaptor and Li-Poly pack correctly according to the connection sketch map. First press "Select" button, "Li" will be shown in the upper right corner of the screen. Press "Set" button to choose “Ni-MH”. The second line reads "series". Further press "Select" button is for charge time setting, which should be set according to battery capacity and charge current. Press "Enter" button to confirm setting. Press "Select" button to jump over voltage setting, which is not necessary for Ni-MH charge. Press "Enter" button to confirm setting. Press "Start/Stop" button to start charging under the fixed data. Caution:
1>In order to ensure charging security, Li-Poly is only allowed to be parallel (balance) charged.
2>In the process of charging, the charger will get very hot. A cooling fan is equipped inside the housing. When the charger starts working, the cooling fan begins to work. In case that the cooling fan does not work (work status of the fan can be judged according to its sound), please stop charging and exchange a new fan, or send it to the retailer or the manufacturer for repair.
