Each adapter has one female XT90 connector splitting to two male XT90 connectors, allowing you to run batteries in parallel. This setup doubles the total capacity (mAh) while keeping the same voltage. For example, two 3S 11.1V 5000mAh batteries become a single 3S 11.1V 10000mAh battery. The design has no wires, reducing resistance compared to standard wired adapters.\u003c\/p\u003e\u003ch2\u003eHow Does a Parallel Connector Work?\u003c\/h2\u003e\u003cp\u003eA parallel connector links two batteries of the same voltage so their capacities add together. This is useful for extending flight or run time without changing the voltage. The FLY RC adapter connects the positive and negative terminals of both batteries directly, creating a combined pack with double the mAh rating. Because there are no wires in the signal path, electrical resistance stays low, helping deliver consistent power to your RC vehicle.\u003c\/p\u003e\u003ch2\u003eWhat Makes This Adapter Different from Wired Versions?\u003c\/h2\u003e\u003cp\u003eMany parallel adapters use short wire leads, which add a small amount of resistance. The FLY RC adapter uses a direct connection between the connectors with no intermediate wires. This design minimizes voltage drop and heat buildup, especially under high current draw. It also keeps the adapter compact and easy to fit in tight spaces inside a drone, helicopter, or car.\u003c\/p\u003e\u003ch2\u003eWhich Batteries Can You Use It With?\u003c\/h2\u003e\u003cp\u003eThe adapter is compatible with any battery that has an XT90 male connector. Common examples are Lithium Polymer (LiPo) and Nickel-Metal Hydride (NiMH) packs used in RC planes, quadcopters, boats, and cars. The adapter itself has one female XT90 input and two male XT90 outputs. Always ensure both batteries have the same voltage (e.g., both 3S 11.1V) before connecting in parallel.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eFLY RC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003eXT90 (1 female to 2 male)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Compatibility\u003c\/td\u003e\n\u003ctd\u003eLiPo, NiMH (XT90 male plugs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Capacity (combined)\u003c\/td\u003e\n\u003ctd\u003eUp to 10000 mAh (example with two 5000 mAh)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e3 adapters per pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Use\u003c\/td\u003e\n\u003ctd\u003eDrone, RC aircraft, car, boat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eCan I use this adapter with batteries of different capacities?\u003c\/h3\u003e\u003cp\u003eIt is not recommended. For safe parallel operation, both batteries should have the same capacity and voltage. Mismatched capacities can cause imbalance and potential damage.\u003c\/p\u003e\u003ch3\u003eDoes this adapter work with XT60 connectors?\u003c\/h3\u003e\u003cp\u003eNo, it is designed specifically for XT90 connectors. XT60 plugs are smaller and not compatible.\u003c\/p\u003e\u003ch3\u003eWhat is the maximum current this adapter can handle?\u003c\/h3\u003e\u003cp\u003eThe XT90 connector is rated for continuous currents up to 90A. The no-wire design further reduces resistance, so it can handle high-current applications typical in large RC models.\u003c\/p\u003e\u003ch3\u003eHow do I connect the batteries?\u003c\/h3\u003e\u003cp\u003ePlug each battery’s male XT90 into one of the adapter’s two male outputs. Then connect the adapter’s single female XT90 to your ESC or charger. Always double-check polarity and that both batteries are at similar charge levels.\u003c\/p\u003e\u003cp\u003eThis FLY RC 3-pack gives you three parallel adapters, so you can set up multiple vehicles or keep spares. The compact, wire-free build is a practical upgrade for any RC enthusiast running XT90-equipped batteries.\u003c\/p\u003e","brand":"FLY RC","offers":[{"title":"Default Title","offer_id":58075755577647,"sku":null,"price":24.61,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/4478\/7503\/files\/fly-rc-xt90-parallel-battery-connector-adapter-3-pack-1-female-to-2-male-for-rc-liponimh-1.jpg?v=1781514480","url":"https:\/\/toysforkid.co.uk\/products\/fly-rc-xt90-parallel-battery-connector-adapter-3-pack-1-female-to-2-male-for-rc-lipo-nimh","provider":"Toys For Kid","version":"1.0","type":"link"}
