Key Features

• XH Balance Plug Compatibility — This charger accepts the popular XH balance plugs found on most modern LiPo battery packs, ensuring broad compatibility with batteries from multiple manufacturers and eliminating the need to source adapters or replacement plugs.
• 2S and 3S LiPo Support — The charger is specifically designed to handle both 2S (7.4V) and 3S (11.1V) LiPo batteries, covering the most common cell counts used in RTF/RTR aircraft, helicopters and RC cars across the UK hobby market.
• UK Mains Power Lead Included — Supplied complete with a UK-specification three-pin mains power lead, you can start charging immediately without purchasing additional cables or adapters, making this a true plug-and-play solution.
• Universal Mains Input Voltage — The charger accepts 100-240V AC 50/60Hz input, meaning it works reliably with UK mains electricity and is equally suitable for use abroad, providing flexibility for RC enthusiasts who travel with their models.
• Dual LED Status Display — Two LED indicators provide clear visual feedback throughout the charging process: a green power LED confirms the charger is connected and ready, a red charging status LED shows when current is flowing to the battery, and when both LEDs turn green, your battery is fully charged and ready to use.
• Balanced Charging Technology — The 300mA balance current ensures that all cells within your LiPo battery pack charge evenly, extending battery life and maintaining optimal performance by preventing cell imbalance, which is critical for reliable operation of your RC car, helicopter or aircraft.
• 12W Charge Power Output — This charging capacity delivers up to 1.0A on 2S batteries (7.4V) and 0.79A on 3S batteries (11.1V), providing efficient charging times without stressing your LiPo packs or requiring excessive charging time.
• Compact and Lightweight Design — Weighing just 120 grams and measuring only 95 x 60 x 32mm, this charger is portable enough to slip into your RC toolkit, range bag or backpack, making it perfect for use at the RC field, in the garage or anywhere you need convenient battery charging.
• Replacement Charger Solution — Purpose-designed as a direct replacement for the basic stock chargers supplied with most RTF/RTR RC models, this charger offers significantly improved charging control and battery protection compared to entry-level alternatives.

Technical Performance

The Etronix Balance Charger represents solid engineering for recreational RC users who need dependable battery charging without unnecessary complexity. Its 12W power output and dual-mode charging capability (1.0A for 2S packs and 0.79A for 3S packs) deliver efficient charging cycles that keep your LiPo batteries in peak condition. The balanced charging system with 300mA balance current actively monitors and equalises voltage across individual cells, a critical feature for maintaining battery health and performance in your RC models. Build quality is straightforward and functional — the compact plastic housing protects internal circuitry whilst remaining lightweight enough for portable use. The dual LED system is deliberately simple yet effective: the green power LED provides instant confirmation of mains connection and unit functionality, whilst the red charging LED and dual-green full-charge indicator give users complete transparency without complex displays or confusing menus. This charger is engineered for the typical RC car UK owner or aircraft pilot who flies ready to run models and needs reliable, fuss-free charging between sessions. The universal 100-240V AC input stage ensures compatibility across UK mains standards (50Hz) and beyond, whilst the XH balance plug connector has become an industry standard due to its reliability and safety features. Materials throughout are chosen for durability and electrical safety, with proper insulation and strain relief on the mains lead ensuring years of reliable service in a hobby environment.

Frequently Asked Questions

• Is the Etronix Balance Charger ET0227 suitable for RC beginners? — Absolutely. This charger is specifically designed as a replacement for the basic chargers supplied with ready to run RC aircraft, helicopters and cars, making it perfect for beginners who want better battery management without dealing with complex charging protocols. The simple two-LED status display makes it immediately obvious when charging is in progress and when your battery is fully charged.
• What types of LiPo batteries can I charge with this charger? — This charger is specifically designed for 2S and 3S LiPo batteries (representing 7.4V and 11.1V respectively), which are the most common battery types found in RTF/RTR RC models. The XH balance plug compatibility covers the vast majority of modern LiPo packs available in the UK RC market.
• How long does it take to charge a battery with this charger? — Charge times depend on battery capacity and which output level is being used. On 2S batteries, the charger delivers up to 1.0A, whilst on 3S batteries it delivers up to 0.79A. A typical 1000-1500mAh 2S or 3S LiPo battery would charge in approximately 1-2 hours, making this ideal for between-session charging or overnight top-ups.
• Can I use this charger outside the UK? — Yes, the universal 100-240V AC 50/60Hz input means this charger will work with mains electricity anywhere in the world. However, you may need a travel adapter plug to connect the UK three-pin lead to foreign socket types. The charger itself requires no modification and will operate normally with international power supplies.
• What does the LED status display tell me? — The charger uses two LED indicators to communicate its status: a green power LED shows the charger is connected to mains and ready to operate, a red charging status LED illuminates when current is flowing into the battery, and when the battery is fully charged, both LEDs turn green. This simple system means you always know exactly what's happening without consulting a manual or display screen.
• Is this charger suitable for LiPo batteries with other balance plug types? — This charger is designed to work with XH balance plugs, which is the most common standard in modern RC batteries. If your LiPo batteries use JST or other balance connectors, you would need an adapter cable, though XH plugs are the industry standard for new batteries.
• What safety features does the Etronix Balance Charger include? — The balanced charging system actively monitors and equalises voltage across individual cells, protecting your battery from dangerous charge imbalances that can cause premature failure or safety issues. The fixed 300mA balance current and output limits (1.0A for 2S, 0.79A for 3S) prevent overcharging, and the LED status system ensures you never leave a battery charging unattended without knowing its status.
• Can I charge multiple batteries at the same time? — This charger is designed to charge one battery at a time via its single XH balance plug socket. If you need to charge multiple batteries simultaneously, you would need multiple chargers or a multi-bay charging station.
