# Charging with the BMS

The BMS is not able to limit the current. It can only disconnect the battery from the output. For charging make sure a current limited power source is used and set the limitation to the right value. \
The BMS is not able to limit the voltage. For charging, the charge voltage should be limited as well.

{% hint style="info" %}
The standard balancing current is only 50mA for one cell. \
This means it could take some time before balancing is done if the battery pack very unbalanced. 
{% endhint %}

To get more information about the charging process see CHARGE state on the [BMS application state machine](https://nxp.gitbook.io/rddrone-bms772/bms4.0-10.1/software-guide-nuttx/bms-application-state-machine) page.
