8.4V / 7.4V Lithium ion/Polymer Charger with 1A Charging Current Lipo Battery Charger with DC head 5.5 * 2.1mm Indicator LED

Input: AC100 ~ 240V

Output: constant current and voltage DC8.4V -1A

DC output line: Soft envelope

DC plug: DC5.5 * 2.1 head to head core diameter 5.5MM 2.1MM socket

 

1, the circuit boards with over-voltage, over current, short circuit protection;

2, the output power is enough

3, high output voltage accuracy

4, the output voltage ripple

5, the standard design, 100% compatible with original battery.

 

built-in EMI filter, low ripple, low noise (MAX 280mVp-p)
charging modes: constant current - constant voltage (CC-CV bypass range of 50 ~ 150mA)

 

short releasing the load, the charger will automatically resume normal operation

 

overcurrent fault is removed, the charger will automatically resume normal operation

 

Overvoltage protection: 

output voltage exceeds the rated voltage, the charger will protect the charger shall restart after troubleshooting to resume normal work

 

105% ~ 150% (FOLDBACK limiting output reset: automatic recovery)

 

charging indicator light red; full, light green; no load, light green; fault, the red light flashes. For 2-string lithium (lithium ion, lithium polymer) battery pack suitable for nominal section 7.2V-8.4V 2 lithium (lithium ion, lithium polymer) battery pack suitable for 8.4V lithium (lithium ion, lithium polymer) battery pack the product is suitable for direct charging lithium battery, the charging mode is the constant flow of constant-voltage, over-voltage over-current short circuit protection, safe and reliable battery charging; clear the Display: red light when charging, lithium when the green light or not attached to a lithium battery when fully charged. Products through testing and certification, product quality, the use of high-voltage precision optocoupler feedback, exports to the EU, through the ROHS certification. Please rest assured buyers use.

 

Note: 

There is no protection board lithium battery protection board lithium battery and charger are the same, interoperability can not charge bad. The lithium battery charger with constant current. Constant voltage charging, the current pre-adoption. 5  constant current charging cell voltage from 3V-4.2V, charging automatically transferred to constant voltage charging phase, which remained unchanged, the charge current gradually decreases, less current is reduced to 0.05 , the battery full, the charging process automatically converted by the red light green light
