STEP 3 - Connect the battery charger to mains power
•
Connect the battery charger to a mains powered socket.
•
Turn on the mains power.
Once the connection instructions have been followed, AC power is presented, power White LED ON. The charger will begin charging
automatically, the “Charging” Blue LED is ON. When full charge is reached, the “Maintaining” “Full” Green LED will be ON. The Main-
taining Float Mode allows the charger to effectively be left connected to your batteries, over the course of a season for Lead acid
batteries, without overcharging your batteries and maintains your battery’s full charge, for a LiFePo4 battery, it will automatically
terminate the charge if the battery fully charged and Green LED will be ON.
STEP 4 - Disconnecting the Bank charger from Battery
Switch OFF and Remove the AC Power Socket from the outlet; Remove the Black lead and then the Red lead. Check electrolyte levels
if possible. (As they may need topping up with distilled water after charging)
CHARGING PROCESS
The bank charger provides the multiple charging phases subjected to the Lead acid battery sensed or LiFePO4 battery sensed.
Force mode stage
Press the Force mode for 3 seconds: the bank charger will activate the low voltage “dead” Lead acid battery and engage de-sulpha-
tion; it will wake up the “dead” LiFePO4 battery where the under-voltage protection has been triggered.
Soft start
In this phase rising voltage and a maximum of 50% of bulk phase current is applied to the battery to start the charging cycle.
Bulk stage
In this phase rising voltage and maximum output current is applied to the battery.
Analysis-1 Stage
In this phase the band charger tests the battery in order to detect bad cells (only for Lead acid batteries). For abnormal cell detection
results please refer to the troubleshooting section.
Absorption stage
In this phase a constant voltage and tapering current is applied to the battery to ensure it reaches 85% state of charge.
Analysis- 2 Stage
In this phase the charger tests the battery again in order to detect bad cells and high levels of sulphation (only for Lead acid batteries)
Float and Maintenance
Compatible only with Lead Acid batteries this stage is used for long term battery maintenance.
Float returns to Bulk charging
When battery voltage is dropped below 12.5V.
LiFePo4 Recharge phase
If the battery voltage falls below 12.8V; the bank charger will automatically return to Bulk phase.
Voltages are set for 12V mode, x 1/2 for 6V mode.

* Only if force mode is selected:
- For lead acid: reconditioning stage.
- For lithium: wake-up stage.
** No float & maintenance stages for Lithium. Once the battery is fully charged, the charge is stopped.
