Are they saying the voltage of a lipo is to high, and this will burn up the servo? Please explain. If I do run this servo in a 1/10th scale buggy, using a 2S 4000-5000mAh lipo pack, what do I need to do? Should I run a voltage reg. and a power cap, and if so, which ones do you guys recommend? Thanks in advance, guys!
It's a 6v servo and so you wouldn't run it directly from a 2s lipo pack however esc BEC's are 6v and so it would be fine running from the esc. Most esc have a 3a supply and so that should be sufficient. If you get glitches or brownouts where the servo seems to struggle you can try a glitch buster power cap (any of them will work) or run it from the lipo with a seperate BEC however I doubt that is needed.
