hello my brothers
I have 1 question, for powering my ssc-32 how much power do I need, if I connect the VL = VS1 jumper, to give the voltage at servos and logical power, so I want to use a battery to give both the voltage

thanks :slight_smile:

You need 6vdc with enough current to power all the servos you are connecting with some spare capacity.

If you are connecting 6 analog servos you should be able to do it with as little as 1500mAh. I have powered a complete 18 servo hexapod using only a 1600mAh pack, but 2800mAh works much better. Batteries have the ability to deliver a huge amount of current. Capacity is usually not an issue of if it will work or not, but how long it will work before the logic browns out or fails completely. This is only true if the wires are heavy enough to carry the current. When powering the logic and servos from the same source the logic will fail first. This usually shows itself as the robot stopping what it’s doing and suddenly going to the power on position. This can cause the logic to fail again and again as the robot tries to hold position and slump over and over. But it’s not caused any damage to any of my bots.

6vdc is max volt to powering 18 servos?
hmm can I use 7.4v for powering 18 servos?

hmm
whether the servos I would be fine if I use a battery like the one above?
does not burn because I give a voltage of 7.4V?

thanks

No you can’t use 7.4vdc on servos. They require 6.0vdc only. They are converting the servos to 7.4vdc, but right now the only affordable one is the 5685. You need to use a high capacity BEC. (regulator)

so for powering 18 servos max 6v right?
how about this sir

That is old information back when we were using a lot of 422 servos in our kits. They did handle 7.2vdc, but I have reworded the document to be more accurate. Sorry for the confusion.

its for servo 422 right?
so if i use servos htx12 and htx5010 that battery can handle?

I do not know anything about these servos. Sorry…

oh okay jim thanks alot
if servos need max 6vdc and the battery have 7.2v can I use bec or some regulator like sentrahelipro.com/index.php? … -REGULATOR

thanks

Yes that is the idea. I have no experience with that regulator.
