Features: brand new high quality Made of high quality material durable 4 strings of 40A lithium battery protection board built-in recovery function - automatic recovery. Enhanced version suitable for electric drills with starting current below 80A and power below 230W (without balance function). Integrate 10 imported low internal resistance MOS tubes continuous discharge 40A suitable for electric drills sprayers LED lights low-power inverters etc. Ideal 4S 40A 4S40A lithium-ion battery 18 650 charger BMS PCB protection board with balance drill motor 14.8V 16.8V lithium battery module. Product parameters: Charging voltage: 16.8V~18.1V Continuous discharge current (upper limit): 40A (If the heat dissipation environment is not good please reduce the load current.) Continuous charging current (upper limit): 20A Dimensions: Approx. 45x55x3.4mm/1.8x2.2x0.13 Scope of application: nominal voltage 3.6V 3.7V lithium battery (including 18 650 26650 lithium polymer battery) Precautions 1. Due to body measurement please allow slight size deviation. 2. This model is an enhanced version of BMS PCB without equalization charge. 3. Four 10C-20C power batteries or eight 5C-10C power batteries are required to successfully start the electric drill (ordinary 18 650 cannot start the electric drill!!). 4. Strictly follow the wiring of 0V 4.2V 8.4V 12.6V and 16.8V. Do not touch any components on the board when soldering wires to avoid short circuits. 5. When welding the battery or charging for the first time as long as the single battery exceeds 4.2V the 430 resistor will heat and discharge (discharge to about 4.19V and stop heating). If the 430 resistor is very hot (too hot to touch) please check whether it is connected wrongly. 6. When connecting 4 sets of batteries in series please ensure that the voltage of each set of batteries is the same. If they are different charge each group of batteries individually and reconnect them in series. In the discharge test the battery whose voltage drops faster is a bad battery. Package Included: 1 * 4S 40A Protection Board Note: 1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.Please allow slight manual measurement deviation for the data.
