Assembly Preparation Guidelines

For new battery assembly:

Use 18650 power lithium battery cells only.
A group of six cells must be balanced with matched resistance and capacitance to ensure equal voltage across all cells.

For repairing an existing battery pack:

Test the voltage at both ends of each individual cell before beginning.
If voltages differ, charge each cell individually until all cells reach the same voltage level.
Important: All cells must be at equal voltage before soldering the PCB board.
