- First of all, it protect the servos, by providing a voltage regulation (5.0V), allowing from now to use 2S lipo battery.
- It also protects the servos from current overloading
- It also indirectly protect the other servos and the receiver from voltage drops, because of high drain current that can happen if a control surface is blocked, or because of a defective servos.
By distributing the BEC function to the servos, you also suppress the single point of failure. You can now use MKS servos with other servos that accept 2S battery. You can combine HV servos and non-HV MKS servos.
This device should be available soon through your MKS distributor/reseller. No idea about the price yet.
