Thank you all for your help!  I already slow down the servos, but they still draw lots of current.  I am searching for a 6V, 15A switcher now.  Do you see any "reference" design out there?

Hello,

I am currently working with C5077 Graupner (same size and torque as a S148)
The max current is around 500mA. So with the last idea to control slowly the
