4. Temperature protect(optional): Battery package 50--60°C

Using 10K MF52 NTC, B=3950    

5.Pulse ratio: 35/512  512mS/Cycle 

(Trickle Charging Mode, each charging time:512mS, stop time:35mS)

6.Timer:2.5-8Hours (Suitable for batteries with capacity 1.2-4.4AH)

 

Safe Protection

1. Over-Current Protection

2. Short-circuit Protection

3. Polarity Reverse Protection

4. Over-temeprature protection

5. Over-load Protection

 

Led display for charge state:

1. Green---no load/ fully charged

2. Red---in Charging

3. Red flashes---Output polarity reverse/ Short-circuit/ low Battery voltage

Pulse Charging

The battery is charging 500mS and stop 35mS. 

That makes the charging progress most effectively and battery package’s temperature rising lower.
