Battery Storage

Storage Mode

Recommendations

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.

Placing Battery Into Storage Mode
  1. Plug the battery’s power cable into the charger

  2. Hold the Storage button for 5 seconds.

  3. The charger will beep, the fans will spin up, and the LCD display will indicate that storage mode has begun.

Self Storage

Recommendations

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. This process will continue until the voltage is 3.90V. The current size of the discharge unit is about 50ma.

(e.g.) The remaining capacity of BMS is about 16Ah. After about 7 days, a single cell will drop to 3.90V.

Self Storing Batteries

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.

(e.g.) 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 and the self-consumption of the BMS system.

Troubleshooting Battery Charging

Error Message

Appears on screen

What you should do: 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

What you should do: 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.
