3 Series 20A 18650 Lithium Battery Protection Board
Lithium Battery Protection Board is your ideal choice for efficient and reliable battery management. This 3 Series 20A board comes with AUTO Recovery, ensuring uninterrupted power for your devices. It's designed for 3.6V, 3.7V lithium batteries, including popular types like 18650 and 26650, as well as polymer lithium batteries.
With a continuous discharge and charge current of 20A, this protection board is a powerhouse, perfect for drills, sprayers, LED lights, and low-power inverters. The integrated 10 low load resistance MOS tube ensures balanced charging with 100mA balanced current, optimizing battery performance.
The board operates smoothly in a wide voltage range, from 16.8V to 18.1V, accommodating different battery setups. Its compact design, measuring approximately 46 x 60 x 3.4 mm, allows easy installation on the battery bundle or in confined spaces. Safety is a priority with our Lithium Battery Protection Board.
Follow the recommended wiring for 0V to 16.8V, preventing short circuits and ensuring reliable, safe operation.
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.
