Yannee 2 Pcs BL1830 Charging Protection Circuit Board for Makita 18V Battery Indicator

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.

Maximum discharge current: continuous 60A pulse a (3). Discharge termination voltage: 13.75V (4). Overcharge protection voltage: single cell 4.25v±0.025v (5). Overcharge protection recovery voltage: 4.1V±0.025v (5). Over-discharge protection voltage: single cell 2.7V±0.08v (7). Over-discharge protection recovery voltage: single cell 3.0V±0.08v (8). High temperature charging protection: >60℃±2℃ (9). Discharge overcurrent protection 1: ≥100A/1s delay protection (10). Discharge overcurrent protection 2: ≥180A/100ms delay protection (11). 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.
