Specifications

Output capacity: 5V / 3A

Power Input: 5.5-21V (2-5S lithium batteries)

Size: 26 * 12 * 11mm (L * W * H)

Weight: 5g

Advantage of switch BEC comparing with normal linear regulator BEC:

Heat emission is reduced effectively, increase efficiency

Take example 4S lipo battery,

1) Output current 5V/1A of normal BEC need 1A input current, power dissipation is 14.8x1=14.8w, while its current about 0.38A will be enough, the power dissipation is about 14.8x0.38=5.6w
