The anti-flash plug-in system with cable strain relief avoids annoying and contact-destroying sparks when connecting the battery to the controller. The capacitors on the controller are also protected. Special SMD resistors are built into the socket to effectively prevent sparking. Can be used for cables up to a thickness of max. 5mm² (10 AWG) Also compatible with the standard XT90 system. The plugs are plugged together up to the nose, here the flash is extinguished within a moment. Press the locking lugs and push them completely together.
