The
VOLT / AMP button
can be changed at any time during charging process.
The LCD also can be treated as an independent voltage meter or thermometer.
A voltage less than 11.5V Volts indicates that the battery is discharged and needs
re-charging.
The unit has a 6-stage charging algorithm.
Diagnose* - Soft Charge – Bulk Charge - Absorption charge – Equalizing Charge* -
Float Mode
Diagnose *
– Only for Lithium battery type, subjected to the Lithium battery initial voltage
then determine if going to Soft start or Bulk charge; if the Lithium battery is
protected by BMS, the controller will automatically send the signal
periodically to the battery terminals to activate the BMS against protection.
Soft start
- When batteries suffer an over-discharge, the controller will softly ramp the
battery voltage up to 10V.
Bulk Charge
- Maximum current charging until batteries rise to Absorption level.
Absorption -
Constant voltage charging and battery is over 85% for lead acid battery; a
Li-ion battery, LiFePO4 battery and LTO battery will close fully charging after
absorption stage, the absorption voltage level will reach 12.6V for Li-ion
battery, 14.4V for LiFePO4 battery; 14.0V for LTO battery.
Equalization *
- Only for WET battery or Calcium battery type, when the battery is deeply
drained below 10V or every 28 days cycle, it will automatically run this stage
to bring the internal cells as an equal state and fully complement the loss of
capacity. (Li-ion, LiFePO4, LTO, Gel and AGM battery do not run
Equalization charge)
