Out of stock3S 60A Lithium Battery Charger BMS 18650 Protection Module Circuit
[Lithium Battery Protection Board] Lithium-Ion Battery Packs need to be Balanced Charged and protected from Over Charge and Over-Discharge. This ensures the safety of the circuit and gives optimum battery life preserving the original capacity through use. You can use this Battery Management System(BMS) to ensure these conditions. It also offers short circuit protection. If you are using a 3S Lithium Battery in your project, you can also use this BMS Module to protect it from short circuits in the circuit. In the event of a short circuit, the BMS will cut power to the battery and restart. The 3 Series 60A 18650 Lithium Battery Protection Board 11.1V 12.6V with Balance for Drill Motor Lipo Cell Module comes with recovery function-AUTO Recovery and Integrated 10 low load resistance MOS tube. It provides a continuous discharge of 60A, 100mA balanced current, for electric drill/sprayer/LED lights/low power inverter. (if the cooling environment is not good, please reduce the load current use). The Scope of Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, a polymer lithium battery) where Charging voltage can be range between 16.8V to 18.1V The board operates smoothly with Continuous charge current of (upper limit): 20A. The balanced version is suitable for starting current below 80A, power 135W below the drill (with balance). The Board comes in a size of approx. 46 x 60 x 3.4 mm which can be easily installed in a compact size or on the battery bundle itself. Features: 3S 11.1V 12.6V 60A 18650 lithium battery protection board (comes with recovery function-AUTO Recovery). Application: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650.26650, a polymer lithium battery). Continuous discharge current (upper limit): 60A (if the cooling environment is not good, please reduce the load current use). Continuous charge current (upper limit): 20A. Suitable for the drills with starting current below 80A, power 135W below. Note: The Successful start of the drill requires three 15C-20C power battery, or six 10C-15C power batteries (ordinary 18650 cannot start the drill!!). Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit. When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above25V, capacity 10uF-100uF) to the motor’s positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube. 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use it in series. In the Discharge test, the voltage drops faster battery that group is a poor battery. Package Includes: 1 x Battery Balance Module Enhanced 18650( 3S, 60A )
