Balance Charger (321B)

Product Description

The use of lithium battery charger DHD321 Intelligent MCU control, may be 2 or 3 lithium polymer batteries or lithium-ion battery to balance the charge.

Charge current for the three kinds of user choice, input power can be selected in accordance with AC adapter or vehicle power supply.

Input voltage: DC11.0-16.0V
Input Current: 1500mA
Single full battery voltage: 4.20V
Repair voltage: 1.50V-3.00V/CELL
Voltage added: 4.16V/CELL
Three charge current: 1.0A 0.6A, 0.3A
Repair current: 200 mA
Balance of current: 200 mA
Balance of precision: 15mV with

Repair bad battery time: 3min (more than the success it has not been repaired, that is not normal charge)
Protection measures: Input polarity protection, output short circuit protection, output over-voltage protection, output reverse protection
Charger instructions: Instructions stall charge (3 LED), single-balanced instructions (3 LED), recharge instructions (a two-color LED)

Charging steps
1. The charger and power supply connections, all LED light 1S at the same time, the charger instructions stall 1A.
2. Inserted in the battery charge before I can use this button to choose the charge current (charging process can also choose to charge current), by the time for a file, 1A - 0.6A- 0.3A-1A such a cycle.

3. Will need to charge two or three in any one (single group) lithium polymer batteries or lithium-ion battery to insert the corresponding battery charger interface (at the same time access is strictly prohibited 2S and 3S battery charge); At this point, the charging instructions to red lights that are rechargeable, when any of them to reach a 4.20V, the corresponding LED will light balance instruction that is balanced.

4. Charging indicator light to be red to green corresponds to the battery that is already full and balanced process.
Notes
1. Connected to power, the power indicator light is not bright, said power supply is not connected well or take anti-polarity power supply (charger and battery will not cause harm).

2. When the battery connected, the corresponding indicator light should be turned into red, said the normal charge; Indicator light does not shine, please check the battery is good or not then the battery voltage is too low (<1.5V/CELL); An arbitrary cell voltage less than 3V, a small battery charging current repair of the repair charge time of 3 minutes; Such as the repair is unsuccessful, 2Hz charging indicator light flashes that the battery has been damaged. When all batteries to achieve 3V, before we move into the high current charging until full charge the green light instructions.

3. Charging is completed, if the batteries continue to open a long time, the self-discharge to enable single cell voltage lower than 4.16V when the charger will re-charge the battery until full again, and this process will be repeated to ensure that the battery is full of state.

4. When the battery must be recharged from the model to carry out a check charge.

5. The charger should be placed on charge storage and dry well-ventilated place, away from sources of heat away from flammable items.

6. Using the same power with a number of the charger, please pay attention to power supply voltage and power.
