Function:
1. Built-in dual IC detects each cell voltage. And remember the number of uses
2.Detection and protection of each battery can be realized.Overheat protection, overvoltage protection, undervoltage protection, overcurrent protection, overcharge protection.
3. all the new series of Makita achieve low voltage shutdown. Cooperate with many power tool factories
4. Stable quality and anti-vibration. It is the best partner of Makita torque wrench and impact drill and angle grinder.
5. Color: Blue, or Green, or Red, etc. any color, PCB color and version number are different according to the actual latest inventory.
Note: PCB colormay be any color according to our stock,If you have special preference for PCB color, please do not order
6. Applicable to 5-cell lithium battery pack bl1815, 10 cell lithium battery pack bl1830 and 15 cell lithium battery pack bl1860, the circuit diagram is as follows:
7. Package include:
1 X PCB ( may be any color according to our stock)
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 six 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.
