Makita 18V 3.0Ah Bl1850B/Bl1840B Lithium Battery Charging Protection Board

Detail: 1. Built-in dual ICs detect the voltage of each battery. And remember the number of uses. 2. Each battery can be detected and protected. Overheating protection, overvoltage protection, undervoltage protection, overcurrent protection, overload protection. 3. The new Makita series realizes low-voltage shutdown. Cooperate with many power tool factories! 4. Stable quality and shock resistance. It is the best partner for Makita torque wrenches, impact drills and angle grinders. 5. Color: Green 6. Suitable for BL1850B/BL1840B lithium battery pack.

Specifications: High discharge rate: 15A Maximum discharge current: continuous 60A, pulse a Discharge termination voltage: 13.75V Overcharge protection voltage: single cell 4.25v±0.025v Overcharge protection recovery voltage: 4.1V±0.025v Over-discharge protection voltage: single cell 2.7V±0.08v Over-discharge protection recovery voltage: single cell 3.0V±0.08v High temperature charging protection: >60℃±2℃ Discharge overcurrent protection 1: ≥100A/1s delay protection Discharge overcurrent protection 2: ≥180A/100ms delay protection Short circuit protection: ≥200A

Preparation before assembly: 1. If using a new kernel, please note: A. Must choose power lithium battery, B. A set of six iron cores must be equipped with resistors and capacitors to make their voltages equal. 2. If the old battery is repaired, please test the voltage of each battery. If the voltage is different, charge each battery to the same voltage value. Very important: Before soldering the PCB, make sure each battery has the same voltage.

Package Included: 1 x PCB circuit board（Only PCB board, other accessories not included） The merchant warrants that their products comply with all applicable laws, and are offered only if they comply with Joom's policies and EU Product Safety and Compliance laws.
