Antiflash with soldering lug
In the case of electric models, it prevents arcing when a drive battery is plugged into the controller.
Important because even at low operating voltages (~ 10 V), a sparkover occurs when the battery is plugged in, which damages the plug contacts. After a certain time, a safe electrical connection is no longer guaranteed (increased contact resistance, voltage drop, heating, mechanical defects). The AntiFlash 70 is connected to the controller and battery.
