614 Mini Coreless Motor 46500RPM DC 4.2V for DIY RC Aircraft 6mm x 14mm Magnetic

Fixed turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full); 2. Increased input reverse polarity protection diode; 3. Using dedicated reference IC, and high-precision sampling resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%).Particularly suitable for LED driver *High-power LED constant current drive *Lithium battery charger (including ferroelectric)
