Hello! I have 6 servos connected together with 4 D cell batteries. Ok, in the first moment all works fine, bet the current is not all the time the same, that why motors start "shake". This project is "robot arm" and that mean all servos have to work at the same time. What I want to ask is, how many mA need for all 6. servos, because I want to buy static power source, something like this - https://www.elfa.se/elfa3~lv_lv/elfa/init.do?item=69-650-70&toc=19681 - main information there are in English. Maybe any other recommendation how to better power 6. 6V servo motors?
P.S Sorry about my terrible English language and these basic questions. :)
