Arming Switch with Spark Arrest - EC3
A must for 8S and up HV operations. Simply hold down push button for 2-3 sec to charge the capacitors with limited current. This will eliminates the nasty arching when the arming plug is plugged into a the Arming Switch. Available in all popular power plugs - this one has EC3 connectors.
These arming switches with spark arrest are made with heavy 12awg wire which has more current handling capability than the arming plug itself. Therefore if you plan to pull more than 50A of current in your setup you should consider adding another arming switch in parallel to share the load. This second arming switch would not need to include a spark arrest since it could be plugged in after the arming plug that does have spark arrest.
