Part 1. Introduction. The performance of lithium batteries is critical to the operation of various electronic devices and power tools.The lithium battery discharge curve and charging curve are important means to evaluate the performance of lithium batteries.

Important technical parameters of lithium battery protection boards include overcharge protection, over-discharge protection, over-current protection, short-circuit protection, temperature protection, internal resistance, power consumption, etc.
When the lithium battery is used in PACK, it is more likely to over-charge and over-discharge, which is caused by the consistency difference of the cell. If the charging and discharging process is not properly controlled, it will be further increased, resulting in the phenomenon of over-charging and over-discharging of part of the cell.

Most lithium batteries have a short circuit protection setting of around 200-300mA. This is usually plenty to protect the battery from damage, but if you are using high-powered devices that can draw more current, you may want to increase the short circuit protection to 500mA or more.
If the load voltage reaches over 300mA immediately, the voltage pin is turned off and the switch tube is disconnected. This feature helps protect the battery cell.
