"The 2in1 LiPo guard+BEC makes every brushless and brushed speed control useable for LiPo batteries. During operation the 2in1 LiPo Guard+BEC monitors at all time the LiPo batteries, so they never get too low discharged. In addition the LiPo Guard also features a strong 6V/5A BEC.
The built-in BEC in speed controls is mostly to weak and is not designed for high input voltage, such as 3S or 4S. That’s where the 2in1 LiPo Guard+BEC comes into play and does all the work!
