The 3 Series 40A 18650 Lithium Battery Protection Board provides a continuous discharge of 40A and 100mA balanced current. It is suitable for electric drills, sprayers, LED lights, and low power inverters. The board operates smoothly with a continuous charge current of 20A. The balanced version is suitable for drills with starting current below 80A and power 135W below the drill (with balance). The board size is approximately 46 x 60 x 3.4 mm, making it easy to install in a compact size or on a battery bundle itself.
Note: Successful drill start requires specific power batteries. Follow wiring instructions strictly and avoid short circuits. When using a brush motor load, connect a non-polar capacitor to prevent reverse spikes. Ensure equal voltage for batteries in series.
Package Includes:
