The protection board is used for 5 series lithium-ion batteries, mainly used in power tools
It uses an IC dedicated to 5S lithium batteries as a processor to detect the real-time voltage, charge and discharge current and ambient temperature of each battery
Stable various charge and discharge protection functions such as overcharge protection, over-discharge protection and short-circuit protection
Low power consumption, working current of about 25uA, static current of about 6uA
Choosing a suitable protection board and using it appropriately is crucial to extend the battery life

Charge Voltage: 19/21V
Single Cell Charge Voltage: 3.8/4.25V
Continuous Discharge Current:8-20A
Overcharge Protection Delay:1S
Note: This protection board is used to protect the battery from overcharging and over-discharging. It cannot replace the charger. You still need a special charger for lithium batteries when charging! After connecting the wires, it needs to be first before there be output
