Overview
The Spektrum Charge Lead with Balance Extension 24 inch IC5 (O-SPMX-1012) is an essential accessory for RC enthusiasts across the UK who demand flexibility and convenience when charging their LiPo battery packs. Whether you're a competitive racer, a weekend basher, or exploring the world of RC cars for the first time, this 24-inch balance extension lead makes it easier than ever to charge your batteries safely and efficiently, even in confined spaces like a LiPo charging bag. Designed by Spektrum, the recognised leader in spread spectrum technology, this charge lead represents the perfect solution for hobbyists who want more control over where and how they charge their RC batteries.
The Spektrum Balance Extensions are purpose-built to extend the JST-XH style balance plug found on LiPo batteries, giving you the freedom to charge your packs in protective LiPo bags without removing them, whilst maintaining clear visibility of the charging process. This is particularly valuable for UK RC hobbyists who prioritise safety during the charging cycle, as LiPo batteries require careful monitoring. The extended 24-inch length means you can position your battery charger away from your charging area if needed, reducing clutter and improving workspace organisation. Whether you're operating a ready to run RC car, truck, or buggy, this balance extension lead works seamlessly with your existing Spektrum charging equipment.
What truly sets this product apart is its universal compatibility. It includes both a normal balance lead for use with Spektrum G1 Smart batteries and competing battery brands, plus a grey Smart wire specifically designed for SPM G2 Smart batteries. This dual-connector approach ensures you're never limited by battery brand or generation, making it a genuinely versatile addition to any RC collection in the UK. The IC5 connector compatibility means it works perfectly with modern Spektrum RC systems and batteries rated for 2S through 6S LiPo configurations, covering everything from small-scale RC cars to larger, more powerful models.

Frequently Asked Questions
- What battery packs does this charge lead work with? — This extension lead is compatible with 2S through 6S LiPo battery packs featuring JST-XH style balance plugs and IC5 connectors. It works with Spektrum G1 Smart batteries, SPM G2 Smart batteries, and non-Smart LiPo batteries from compatible manufacturers, making it highly versatile for most modern RC vehicles including RC cars, trucks, and buggies available in the UK market.
- Why do I need a 24-inch balance extension for my RC batteries? — A 24-inch balance extension allows you to charge your LiPo batteries whilst keeping them safely inside a protective LiPo charging bag or remote charging location, away from your main charging station. This setup reduces fire risk, improves workspace organisation, and gives you the flexibility to charge batteries in your preferred safe location without moving your charger itself.
- Is this suitable for beginners? — Absolutely. If you're new to RC and learning about LiPo battery safety, this extension lead is an excellent investment because it encourages safe charging practices by allowing you to charge batteries in a protective bag away from your main work area. It's simple to use, reliable, and compatible with standard Spektrum chargers and most third-party chargers that support JST-XH balance plugs.
- What's the difference between the normal balance lead and the grey Smart wire included? — The normal balance lead works with Spektrum G1 Smart batteries and any non-Smart LiPo packs with standard JST-XH connectors. The grey Smart wire is specifically designed for SPM G2 Smart batteries, which feature enhanced charging intelligence and telemetry capabilities. By including both, this lead covers every Spektrum battery generation, ensuring you're never without the right connector.
- Is this extension lead durable for regular use? — Yes. The Spektrum Charge Lead is engineered with quality materials and construction methods typical of Spektrum's recognised leadership in spread spectrum technology. The 24-inch length is substantial enough to provide genuine practical benefit whilst remaining robust enough for repeated use without degradation, making it a long-term investment in your RC hobby.
- Can I use this with non-Spektrum chargers? — This extension lead features standard JST-XH connectors and IC5 compatibility, which are industry-standard connections used by many RC chargers beyond just Spektrum equipment. As long as your charger supports JST-XH balance plugs and IC5 connectors, this extension lead will work perfectly, though we always recommend confirming compatibility with your specific charger model before first use.
