Max Voltage Protection :
O.P.T ( Protect for environment temperature ) :
For a LI-ION battery charger start, if the temperature exceeds
50°C or falls below 5°C, the charger shall not charge and the charge indicator will
show no charger current.
If the environment temperature is below 50°C the charger shall auto re-
Charge. The thermistor of the battery pack will detect the environment temperature.
The trickle charge:
If the LI-ION battery voltage is below 3V/cell,the charge controller will enter the trickle
charge mode. The trickle charge current is about 200~300 mA (trickle charge time is 60
minutes max).
Charger full :
When the battery is fully charged, the charge controller will send a full signal and the gas
guage indicator will display capacity greater than 90%.
For the smart battery, the charge controller full signal and the gas gauge are different.
It’s normal for the gas gauge indicator to show a 90% charge even if the battery has just
been fully charged and is actually above a 90% capacity.
Battery empty shutdown :
When the battery is empty, the charge controller will send a shut down signal within 3
seconds. The shut down signal is 3.3V.
