Designed from ground up, the XT90s power connector comes with 4mm gold plated connectors are perfect match for high current RC hobby applications. The positive terminal has electrically separated 2 sections within the same bullet. When you plug in the connector the first part which is low current (powering via a 5.6 ohm resistor) will charge up the capacitors at a slow rate eliminating the ‘pop’ and once fully seated the second section will deliver the full current bypassing the resistor in the first section. This will help in eliminating the initial surges safe guarding all electronics behind the anti-spark connector. The connector shape also eliminates any risk of accidental reverse polarity connections.
