Key Features

• 4S XH Connector Format — This extension lead is specifically designed for 4S LiPo batteries equipped with XH-format balance connectors, which are standard on many modern RC batteries used in cars, trucks, aircraft, and other RC models throughout the UK hobby.
• Approximately 200mm Length — The 200mm length provides substantial extension capability without excessive cable bulk, allowing you to route your balance connector from a crowded battery bay to a distant charger or balance board with ease and without strain.
• Reduces Physical Strain on Balance Wires — By eliminating the need to stretch or bend battery balance wires awkwardly during charging or storage, this lead helps prevent fatigue damage and maintains the structural integrity of your battery's internal balance circuit, extending battery lifespan and improving safety.
• Improves Charging Station Organisation — The extended reach allows you to position your 4S LiPo battery away from your charger's main unit, creating a neater, more organised charging area and reducing the risk of accidental damage to both battery and charger during the charging process.
• Universal XH Balance Board Compatibility — Works seamlessly with all balance boards and chargers featuring XH-format balance ports, including popular RC charging solutions used by hobbyists throughout the United Kingdom, making it a versatile addition to any RC enthusiast's toolkit.
• Compact and Lightweight Design — The extension lead adds minimal weight and takes up virtually no space in your RC field bag or workshop, making it ideal for keeping as a spare accessory alongside your other RC charging equipment and battery management tools.

Technical Performance

The Fusion 4S XH Balance Extension Lead 200mm is manufactured to exacting standards that match the quality expectations of serious RC hobbyists. The connector is specifically engineered for the XH balance format, which is the industry-standard connector for modern 4S LiPo batteries used across a wide range of RC applications including brushless RC cars, electric RC trucks, RC aeroplanes, RC helicopters, and more. The lead measures approximately 200mm in length, providing sufficient extension for typical RC charging setups whilst remaining compact enough for easy storage and transport.

The internal wiring is constructed from high-quality materials designed to handle the low-amperage balance charging currents safely and reliably, ensuring that each of your four LiPo cells charges evenly and reaches the correct voltage. The lead's design reflects Fusion's commitment to quality and safety in RC battery management, making it a trusted choice for RC Model Shop customers across the UK who demand reliability and durability from their charging accessories. Whether you're charging for a casual weekend bash with your RC buggy or preparing your batteries for serious competition racing, this extension lead will serve reliably and without compromise.

Frequently Asked Questions

• What is a 4S XH balance extension lead used for? — A 4S XH balance extension lead connects between your 4S LiPo battery's balance port and your charger's balance board, allowing you to extend the reach of the connection when your battery is stored in a confined space, such as inside an RC car's battery bay or aircraft fuselage. This prevents strain on the delicate balance wires during charging and storage, protecting your battery investment.
• Is this extension lead compatible with my 4S LiPo battery? — Yes, this Fusion lead will work with any 4S LiPo battery that features an XH-format balance connector. The XH connector is the industry standard for modern 4S batteries, and you'll find it on batteries used across brushless RC cars, electric RC aircraft, RC boats, and countless other applications. Check your battery for an XH connector to confirm compatibility.
• Can I use this lead with different cell-count batteries? — No, this is specifically a 4S extension lead and is designed exclusively for 4S LiPo batteries with four balance wires. Fusion manufactures separate extension leads for 2S, 3S, and 6S batteries, each with the correct number of balance pins for their respective cell counts. Using the wrong extension lead could damage your charger or battery.
• What is the difference between XH and other balance connector formats? — XH is one of several balance connector formats used on LiPo batteries. The XH format uses a distinctive rectangular plastic housing and is favoured by many manufacturers for its durability and secure connections. Other formats include JST EH, which is used on some older batteries. You must match the extension lead's connector type to your battery's balance connector type.
• Is this suitable for beginners? — Absolutely. This extension lead is an essential accessory for anyone charging 4S LiPo batteries, regardless of experience level. It's simple to use—just plug it between your battery and your charger's balance board—and it immediately improves safety and convenience. Beginners benefit especially from the reduced strain on balance wires, which helps protect valuable batteries from damage.
• How long is 200mm? — 200mm is approximately 7.87 inches, or just under 8 inches. This is a moderate extension length that provides sufficient reach for most RC charging setups without creating excessive cable bulk. If you need even longer extension, Fusion may offer alternative lengths, but this 200mm option is the most popular choice for typical RC workshop configurations.
• Do I need a balance extension lead? — Not absolutely, but most serious RC hobbyists find one essential. Without an extension lead, you must position your battery very close to your charger's balance board, which can place awkward bends or stress on the balance wires. This can lead to internal damage that gradually degrades battery health. An extension lead solves this problem completely and costs very little, making it one of the best-value accessories you can buy for battery care.
