Overview
The Spektrum Charge Lead with Balance Extension 24 inch IC2, 2-4S (Model O-SPMX-1010) is an essential charging accessory for RC enthusiasts across the UK who demand flexibility, safety and convenience when powering up their LiPo batteries. This purpose-built charge lead extends the charging distance between your battery and charger, allowing you to position your batteries safely inside a LiPo safety bag or away from your work area whilst you continue building or maintaining your RC car, truck, quad or aircraft. Whether you're a dedicated racer, a weekend basher, or someone new to the RC hobby in the UK, this charge lead solves one of the most common workspace challenges: limited bench space and battery safety.
Spektrum has engineered this charge lead with high-quality cable sleeving that keeps your wiring organised, tangle-free and protected from damage during regular use. The 24-inch length provides genuine flexibility for your charging setup, whether you're working in a cramped garage, at the track, or in a workshop. This lead is wrapped in premium sleeving to ensure durability and a professional appearance that matches the quality of genuine Spektrum products.
The SPMX-1010 features an IC2 battery connector and an IC3 device connector, meaning you can plug your IC2-equipped battery directly into the lead without requiring any additional adapters. The lead then connects seamlessly into the IC3 port on Spektrum Smart Chargers, creating a safe and efficient charging pathway that works with both first-generation (G1) and second-generation (G2) Spektrum Smart batteries, as well as standard non-Smart batteries from other manufacturers. This universal compatibility makes it one of the most versatile charge leads available for RC hobbyists in the UK.

Technical Performance
This charge lead represents genuine engineering excellence from Spektrum, one of the world's most respected names in RC radio systems and charging technology. The 24-inch cable length is precision-measured to provide practical extension without introducing unnecessary resistance that could slow charging times. The IC2 connector specification ensures compatibility with modern Spektrum battery packs and chargers, whilst the IC3 device-side connector plugs directly into Spektrum Smart Chargers without adapters. The construction uses quality connectors rated for the current demands of LiPo charging, and the protective cable sleeving is designed to withstand repeated flexing and coiling without degradation. This lead is engineered to work seamlessly with 2S, 3S and 4S LiPo battery packs, the most common configurations used in RC cars, trucks, buggies and small aircraft throughout the UK. The balance extension functions with both JST-XH style balance plugs common on G1 Smart batteries and the updated connectors on G2 Smart batteries, making it a future-proof investment for your RC charging infrastructure. The grey Smart wire designation for G2 batteries ensures proper identification and safe charging parameters are maintained automatically by compatible Spektrum chargers.
