The 3 Series 20A 18650 Lithium Battery Protection Board 11.1V 12V 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 20A, 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 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 battery bundle itself. At its core, the protection board is responsible for monitoring and controlling the charging and discharging processes of the battery cells. It achieves this through a combination of integrated circuits, resistors, and other electronic components. The “3 Series” designation indicates that the board is designed to manage a battery pack of three 18650 cells connected in series. This configuration allows for higher voltage output while maintaining a compact form factor, making it suitable for a wide range of applications such as portable electronics, power banks, and electric vehicles. One of the primary functions of the protection board is to prevent overcharging of the battery cells. Overcharging can lead to excessive heat generation, electrolyte decomposition, and ultimately, thermal runaway—a potentially hazardous situation where the battery can catch fire or explode. The protection board continuously monitors the voltage across each cell and interrupts the charging process when the voltage reaches a predetermined threshold, thus safeguarding against overcharge events. Similarly, the protection board also guards against over-discharge, another common cause of battery failure. Over-discharging occurs when the battery is drained beyond its safe operating voltage, leading to irreversible damage to the cells. To prevent this, the protection board disconnects the battery from the load when the voltage drops below a certain threshold, thereby preserving the battery’s lifespan and performance. Moreover, the 20A rating of the protection board denotes its capability to handle high-current applications. This is particularly important in devices that demand significant power output, such as electric vehicles or high-performance tools. The board incorporates robust MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) or similar switching devices to efficiently control the flow of current, ensuring minimal power loss and optimal performance. Additionally, the protection board may include features such as temperature monitoring and short-circuit protection to further enhance the safety and reliability of the battery system. Temperature sensors detect abnormal temperature rises within the battery pack, triggering protective measures to prevent thermal runaway. Short-circuit protection mechanisms swiftly disconnect the battery in the event of a short circuit, mitigating the risk of damage to the cells and surrounding components. In summary, the 3 Series 20A 18650 Lithium Battery Protection Board plays a vital role in ensuring the safe and reliable operation of lithium-ion battery packs. By monitoring voltage levels, controlling charging and discharging processes, and offering additional safety features, this protection board contributes to the longevity and performance of battery-powered devices across various industries. Features: 3S 11.1V 12.6V 20A 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): 20A (if the cooling environment is not good, please reduce the load current use). Continuous charge current (upper limit): 20A. Suitable for drills with a starting current below 80A, and power 135W below. Note: The Successful start of the drill requires a three 15C-20C power battery, or six 10C-15C power battery (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. 4 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. The Discharge test, the voltage drop faster battery that group is a poor battery. Package Includes: 1 x 3 Series 20A 18650 Lithium Battery Protection Board 11.1V 12V 12.6V.
