7.4 Maintenance
The Li-Ion battery is maintenance free. Charge the battery to approximately > 80% of its capacity at
least once every year to preserve the battery’s capacity.
7.5 Storage

The battery product should be stored in a dry, cool and cool environment;

Generally, the maximum storage period at room temperature is 6 months. When the battery is
stored over 6 months, it is recommended to check the battery voltage. If the voltage is higher
than 48V, it can continue to store the battery. In addition, it is needed to check the voltage at
least once a month until the voltage is lower than 48V. When the voltage of the battery is lower
than 48V, it must to be charged according to the charging strategy.

The charging strategy is as follows: discharge the battery to the cutoff voltage with 0.2C
10
A
current, and then charge with 0.2C
10
A current for about 3 hours. Keep the SOC of the battery
at 40-70% when stored;

When the battery product is stored, the source of ignition or high temperature should be
avoided and it should be kept away from explosive and flammable areas.
8. Troubleshooting
To determine the status of the battery system, users must use additional battery status monitoring
software to examine the protection mode. Refer to the installation manual about using the monitoring
software. Once the user knows the protection mode, refer to the following sections for solutions.
