Warning

1.When single IC is used in a multi-node cascade solution, the pcm will lose its protection function when thevoltage is lower than the minimum operating voltage of the IC
2.After the battery pack is assembled, charge and activate the pcb in the first step
3.When using this product, you must take anti-static measures to prevent it from being damaged by electrostatic shock
4.Please weld the wires from low potential to high potential one by one in order and avoid pseudo solder joints. 
5.When installing the pcm, attention should be paid to avoid the damage of the pcm by mechanical pressure, and the assembly should not be too tight or forced to squeeze the assembly
6.Do not use liquid flux, because it will flow to nearby components causing a short circuit, it is also corrosive.
7.
Do not make the electric lead, soldering iron, tin slag touch with the components when welding in order to prevent from destroying the pcb, must clean it promptly.
