12V 15A LiFePO4 Battery Charger Features:
Microprocessor Control (CPU).
High frequency switching mode power supply technology. DC isolated
from AC.
Multi 3-stage automatic charging: Automatic charging protects your
battery from being overcharged. So you can leave the charger
connected to the battery indefinitely.
Customized charging steps for Lead-acid battery: CC, CV and Float.
Customized charging steps for Lithium battery: Pre-charge, CC and
CV or Shut-off at the end of charging.
Input Characteristics:
Input Voltage: 110/230V AC
Input Frequency: 50Hz or 60Hz and single phase.
Efficiency: ≥85.0% @230Vac/50Hz(Typical full load)
Input socket: EU/AU/UK/US/Italy/India customized
Charging Characteristics:
Pre-charging step: start with small current (often set 20% of CC
3A) to protect over discharged battery.
Constant Current (CC) step: charge with max 15A current for fast
charging purpose.
Constant Voltage (CV) step: charging current begins to drop from
max 15A and voltage reached max set 14.4V or 14.6V or 14.7V.
Floating step: voltage goes to set 13.5V or 13.8V and charging with
small current, often set 20% of CC, till to fully charged.

Protection for 12V 15A LiFePO4 battery charger
Over Voltage Protection: The battery charger will be auto recovered
when faults remove.
Over Current Protection: Charger output current does not exceed the
set maximum battery charging current.
Over Short Circuit Protection: Battery charger output can be
shorted without damage No odor, smoke, fire, plastic deformation,
and excessive heal happen. The power shall be auto-recovery. (It
will enter into normal condition when then the fault condition is
removed)
Over reverse polarity Protection: When the battery charger output
terminals reversed after the charger will not work until it’s
connected correctly.
