Hi,
I used the 1n4004 rectifier diode.
I used it in both directions with different ones, (not at the same time). From negative to positve, and from positive to negative.
What do you think about that device of the link in my previous post?
It won't do anything for you. You need to find the source of the surge and eliminate it. Please tell me exactly how you connected the diode. Saying "From negative to positive" and such doesn't mean anything to me. Where exactly did you connect it. Was it parallel to the motor, etc.
1) I don't know what your diagram means. Please post a proper schematic that shows the circuit.
2) The diode goes across ( parallel to ) the motor
3) Please look up the definition of parallel and series.
It must be connected to the motor. It won't work by simply connecting to the battery. You don't have any path to a solution if you can't connect to the motor, as far as I know.
I can see it very well, I dont want to open it and modify the device, if i do, then it needs an engineer to do a full report, and pass all certificates or aprovals.
If i do something external, then I am not modifying the machine.

That sort of sounds suspicious to me being 11.1 volt LiPo is typically cordless hand tool or toy power.
What is the actual device you are working with anyway and the true reason for the sparking concern? Its almost impossible to help anyone who does not give the full information relating to the supposed problem at hand.
