2S Lipo Vs Servo

First I like to say that i'm very happy with your products But here we go:) A fully charged lipo puts out 8.2 volts and the servo's that are in the kits can have max 7.4 volts. I used in my projects cheap towerpro 995 servo's and a stepdown regulator to put out max 6 volts because if i put the full lipo voltage on them they begin to smell funny and start to work as a smoke generator. I am starting to replace the cheap servo's with ez-robot servo's but dispite the fact that a compleet robotkit has a lipo i am worried that the servo's will go up in smoke.

I also fly rchelicopters and those servo's use 5 volt and i never have burnt out one so can the ez-robot servo deal with the output voltage of a lipo battery?

All ez robot robots use a 7.4V lipo (peaked 8v+) batteries so the ez robot servos are meant to to be used with them... I use 7.4v lipos with cheap tower pro 995 servos with generally no issues... I think the quality of the 995s are the issue here as these servos are knock offs of knock offs and so on... They should be able to handle a fully charged 7.4 lipo, but if they smoke it's probably due to poor quality rather than the increased voltage....
