3.2
Software over voltage
protection
The charger software limits the maximum output
voltage to a level suitable for the connected battery
system
3.3
Thermal cutback
When the internal temperature rises to 85
℃，
it turns
into pulse charge mode. The pulse mode charges
battery minutely with alternate currents 2A and 8A,
which will reduce charger internal temperature. When
the internal temperature drops to 60
℃
, the charger
comes back to previous charge mode.
