<p><b>NEW VERSION 45A!!</b></p><p><b><br></b></p><p><b><br></b></p><p>The 4-in-1 ESC not only includes 4 high-performance 45A ESCs, also an Amp/Volt monitoring port which allows FC to monitor the volt &amp; amp in real time (on condition that the FC supports this function); it’s as small as a FC for FPV(s) and easy for installation and wiring. With the remarkably small size, it's a perfect match for competition FPV(s)</p><p><b><br></b></p><p><b>Features:</b></p><p><br></p><p>Super Small &amp; Light: &nbsp;ESCs with incredible small size (20x20mm mount) and light weight are specially designed for competition FPV drones</p><p>Quality components: EMF8BB21F16G MCU , 3-in-1 drive IC, High quality American Fairchild MOSFETs</p><p>BLHeli_32 firmware ready: Users can flash or upgrade the BLHeli</p><p></p><p>Hardware Generated PWM &amp; Damped Light Mode: &nbsp;The ESC firmware uses hardware generated motor pwm for smooth throttle response and silent operation. Damped light does regenerative breaking, causing very fast motor retardation, and it inherently also does active freewheeling.</p>
