• Clearing Cell Imbalance
Clearing cell balancing requires having a stable charge source and prolonging the charge process so
that balancing may take effect. Balancing cannot be carried out if there are any overvoltage warnings
and will also not be carried out if the total charging current reaches 0, indicating the battery is fully
charged.
The balancing algorithm is only carried out during charging, triggered when both the following
conditions are met:
1. Single cell voltage reaches 3.4V
2. The voltage difference between cells is above 60mV.
When the balancing starts, the cell(s) with high voltage will be discharged at 50mA. The balancing will
be ON for 1 sec, then OFF for 1 sec. As long as both the above conditions are met, the balancing cycle
will be carried out intermittently. It can't be a continuous process, to avoid overheating of the resistor
in balancing circuit.
Cells can be balanced by the following method:
1. Review the Samkoon screen to verify the system is not any alarm state – warning or
protections.
2. With the lithium system operational and clear of any faults:
A. Discharge the system to below 53.0V.
B. Let the battery sit idle for 10-15 minutes.
C. Observe and note the Total Voltage, Max_Volt and Min_Volt.

If the Max Cell is above 8000mV or the Min
Cell is below 2000mV, the battery is likely
compromised and will require replacement.
