6 -To perform the protection functions, the BMS must be able to disconnect the battery from the load and charger. To do this, **at least one contactor** able to break the load and charge circuits must be connected to the BMS.
7 -
8 -Before use, **configure the system**. Proper operation of the BMS is possible only if it is correctly configured.
9 -
10 -It is not recommended to use the system in batteries formed by several series of cells connected in parallel. To increase capacity, it is recommended to connect several cells in parallel groups, and then connect the groups in series.
