Short circuit protection：No
Weight: 6.7g
Size: 3x1.8x1.3 cm

*This device is specially introduced to those experienced DIYers, basic electronic knowledge and DIY/welding skills are required, we are not responsible for damages due to lack of welding skills or wrong wirings etc.

*Check the output voltage and adjust the virable resistor to adjust the voltage if needed before connect to your device.
Includes/Requires:
Includes:
1 x voltage regulator

* Wires are not provided, customers need to weld the input and output wires yourselves, so basic welding skills are required, also wrong polarity will cause severe damage to the unit.

F****enheit-145
Grade:
This is a STEP UP CONVERTER!! Not a Voltage-Checker...
I put in this in Security-Lamps with only 1 LiIon Cell to step up the Voltage to 14,3V for the LED´s lightning stronger.
If the Voltage falling lower than 2,6V the LED´s are flashing verry fast.
This you cannot take for LiPo they will destroyed while Low Cell voltage.
Also you can Take LiFepo because lower than 2.4V Converter stops working.
For stability and the Price I give 5 Stars

Discussion of this review:
 
no low voltage protection... you should build a voltage supervisor circuit or decide to use a "Low Voltage Buzzer for 2S/3S/4S Lipo Battery" in addition. This circuit is only a switch mode PS -adapter.
