ESCs from Skylord-6A to Skylord-30A use a linear battery elimination circuit (BEC) to output a 5V voltage for powering other devices, such as the receiver. The linear BEC has the advantage of small size and low interference. However, the efficiency is low, only 65% to 70%, and more power will be wasted and converted into heat. This type of voltage regulator is unsuitable for high input/output voltage difference or high current applications. It's generally only used on 3S or below.

ESCs from Skylord-40A to Skylord-100A use the ultra BEC (UBEC). Compared with the linear BEC, the UBEC has higher efficiency, lower loss, and higher output drive capability. Then the UBEC is more stable and reliable in heavy load conditions.

Continuous Current: It is the maximum Constant Current that the ESC can work on. A larger constant current will cause the ESC will overheat and burn out. For example, for a TC-P-3510-KV1080 TomCat motor, the maximum current of which is 30A, you should choose an ESC with a continuous current greater than 30A. It is better to choose the Skylord-40A-UBEC. In addition, there will be no power gain to your motor when using ESC with too many amps. Using 40A ESC doesn't mean your airplane is flying faster than 20A ESC; instead, your airplane will be heavier.

Burst Current: this might allow a higher current to pass through for a short time, such as 10 seconds. Over this time, the ESC will burn out.
