BL1890B Lithium Battery Case BMS PCB Balance Charging Protection Board Shell for 18V BL1860 9.0Ah LED Indicator

BL1890B Lithium Battery Case BMS PCB Balance Charging Protection Board Shell for 18V BL1860 9.0Ah LED Indicator Beschreibung

This can fill 15 pieces of 18650 power li-ion batteries, But this is only a shell, there is no battery inside.
This product is component without battery core. It is used to repair and assemble batteries pack, only for people who are familiar with battery performance and have practical experience in battery assembly.
No Original, new, No Battery Cell !!!!!!
BMS Balanced charging fuction: through the battery management system, ensures that the voltage of each battery cell is basically consistent, ensuring that each battery cell is fully charged, avoiding certain cell voltages being too high or too low, improving utilization efficiency, ensuring the performance of the battery pack, and thus extending the service life of the battery pack.

Please be kindly noted:
If you have any objection to the following two items, please do not order!
(1). PCB color may be any color according to our stock,
(2). PCB design may change with the same function and performance guaranteed.
(3). The number and position of components the PCB may change and be adjusted.
Preparation before assembly:
(1). If a new core is used, please note:
a. 18650 power lithium battery core must be selected,
b. A group of 5/10 cores must be equipped with resistance and capacitance to make their voltage the same.
(2). If the old battery is repaired, please test the voltage at both ends of each cell. If the voltage is different, please charge each cell to the same voltage value.
Very important:
Ensure that the voltage of each cell is the same before welding PCB.
Color: Black
Material: plastic
