View Full Version : [Project] Worried about amp load on some servos

I don't know the battery I need for these servos. There are mg945 13kg servos and also cys so150 13 kg. I know the voltage should be between 5 and 7 appx. But what about the amps?

How many servos are you using, and what kind of application are you using the servos for?

Those servos are made for 5-cell NiMH battery packs. If you actuate them all at the same time into stall, they can each draw several amps. The bigger the capacity and the bigger the current rating of the batteries, the better.

If you don't want to use NiMH batteries, 2S LiFePO4 batteries will also work. These will be 6.4 or 6.6 V nominal. If you use more than one or two servos at the same time, you want 10C or better batteries for high current capacity.
