IF1200A Pilot Operating Handbook 9. Battery Charging
Storage Mode
If a battery will be shipped or will not be used for long periods of time, it is highly recommended
to put the battery into storage mode. Depending on the battery’s state of charge, putting the
battery into storage mode will either charge or discharge the battery to a voltage that is most
stable for shipping and sitting for long periods of time.
To place a battery into storage mode, plug the battery’s power cable into the charger and hold
the Storage button for 5 seconds. The charger will beep, the fans will spin up, and the LCD
display will indicate that storage mode has begun.
Self Storage
The Internal Battery Management System supports high-power discharge. Considering the
internal structure and safety of the cells, when the battery is fully charged, if the battery is static,
there is no communication, and there is no high current, after waiting for 120 hours, the battery
will turn on automatically. The discharge circuit, the current size is about 50ma. This process will
continue until the voltage is 3.90V. For example, the remaining capacity of BMS is about 16Ah.
After about 7 days, a single cell will drop to 3.90V.
When the cell voltage reaches 3.90V, the peripheral self-discharge circuit will stop working. At
this point, the MCU will continue to enter a low-power sleep mode. at this time, For example:
when the cell voltage is 3.90V, the remaining capacity of the BMS is about 8Ah, and at a normal
temperature of 25'C, the capacity of self-consumption for a month is 500mAh, including the cell,
including the self-consumption of the BMS system.
Troubleshooting Battery Charging
Error message appears on the screen:
● Unplug the battery and press the ‘Charge’ button to reset the interface.
Popping or arcing when plugging the battery into the charger:
● The battery likely needs to be balanced. Plug in the balance cable to both the charger
and battery, then plug the main lead of the battery into the charger to conduct a balanced
charge.
