Do not charge it in the discharge port The products are constantly updated and improved and some small components are changed from time to time such as resistance and diode but it will not affect the use!Cannot serve as the condition that opens dispute! TheBMS is for 5 series Li-ion batteries mainly used for electric power tools It uses special IC for 5S lithium batteries as processor to detect real-time voltage charge and discharge current and ambient temperature of each battery Stable various protective functions for charging and discharging such as overcharge protection over-discharge protection and short circuit protection. Low power consumption the working current is about 25uA and quiescent current is about 6uA. Choosing the correct protection board and applying it appropriately is vital to the longevity your batteries Charge Voltage: 21V Single Cell Charge Voltage 4.25V Current Continuous Discharge Current 8-20A Overcharge Protection Overcharge Single Cell Detection Voltage 4.25V Size: 5.7*6.3cm Package Included:1pc Note: 1.
