Product Description
Product Description
This protection board uses three series of lithium battery ICs for power tools, IR imported ultra-low internal resistance MOS, less heat generation, resistance capacitors use Yageo capacitors and Samsung capacitors, all of which are the materials of big brand first-line manufacturers, so it is protected. The current is larger and the shock resistance is better.
The protective plate has the following characteristics:
(1) Built-in high-precision voltage detection circuit;
(2) The terminals connected to the charger use high-voltage devices;
(3) Built-in three-stage protection detection circuit (overcharge voltage protection, overdischarge voltage protection, load short circuit);
(4) The charge and discharge of the battery can be controlled by the MOS tube;
(5) Wide operating temperature range: -40°C ~ +85°C;
(6) Low current consumption.
Uses:
3 strings of protection boards are specially used on power tools, portable vacuum cleaners, and electric screwdrivers. The instantaneous starting current is large, and the short circuit does not burn the board.

Wire Diagram
Wiring precautions:
1. Installing the protective board requires a certain amount of technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
