ESC connection to the batteries


I have a small problem when I connect my bateries on my ECS, I have an electric arc in the XT60 connects, do you also this phenomenon, someone has there a solution to avoid this phenomenon, must I put a interrupter on ESC?


Search for anti-spark Connector/switch.
There is a discussion on the forum.
The caps inside the ESC are loaded when you connect your battery. So it is normal, but to avoid higher resistance you should use a power switch or anti spark connector.


great, thanks for your answer
