Description:
Circuit control: 5V step-down circuit, constant current output, to ensure that 5.8-12V power supply through the light output stability
Size: 10.2 * 22mm (width * length)
Reverse protection: a unique reverse protection design, do not worry about the battery rather than the burning plate
Polarity definition: module shell is positive, the end of the pad is negative.
WARNING: In order to ensure safety,we recommend to use imported two-stage protection board 3.7V lithium battery (16340,18650,14500 and 18500 power supply).Do not use low-quality battery, because double lithium in the internal resistance of the battery capacity and discharge performance requirements,especially prohibiting the use of three or more cylindrical lithium without a protective plate.
Perhaps many friends will usually use three parts without any explosion, if using three, a large resistor,and all the buck chips in the 5.8-6V Start work, even if there is no undervoltage protection is invalid, the circuit out of control, will lead directly to the short circuit can produce an explosion, the power of steel shell is very large, of course, this percentage is unlikely, but as long as the consequences unbearable!
You can use the 6-30V DC power supply directly, or use two strings and three strings of polymer lithium batteries,
which are currently the safest of all lithium.
