EcoPower XT-90 Connector Set. XT90 connectors provide a mechanically solid, low resistance, high-amp capacity connection and a great option for high current applications like drag racing and 1/8 scale e-buggy. EcoPower XT90 Connectors feature gold plated 4.5mm bullets molded into a high-temp Nylon housing. Additionally, these connectors feature a snap on sheath that is used to protect the solder joint, creating a much cleaner looking installation compared to heat shrink. Package includes one female and one male connector.
