• Multi-Chemistry Support — Supporting LiPo, Li-ion, LiFe, NiCd, NiMH and lead-acid batteries with cell count ranges from 1-6 cells (Li-ion/LiFe/Polymer) to 1-18 cells (NiCd/NiMH) and 1-10 cells (lead-acid 2-24V), this charger handles virtually any battery type you're likely to encounter in the RC hobby.
• Discharge Capability — The 25-watt discharge function allows you to safely discharge batteries before storage, maintenance or repair, with a maximum discharge current of 5.0 amps, extending battery lifespan and improving safety.

Technical Performance

The eTronix PowerPal 4.0 is engineered for reliability and precision in demanding RC environments. Operating from an input voltage range of DC 11-18V, it accepts power from standard UK mains supplies via external power adapters or direct 12V/18V power sources. The charger's maximum charge power of 200W combined with a charge current range of 0.1-10.0A provides exceptional flexibility whether you're slow-charging a single small battery at 0.1A or rapidly charging large-capacity 6S LiPo packs at 10A for ready-to-run RC cars. The discharge function offers a more modest but still useful 25W maximum discharge power with currents from 0.1-5.0A, perfect for safe battery storage procedures. For balance charging LiPo, Li-ion and LiFe batteries, the charger delivers 200mA per cell, ensuring every cell reaches identical voltage levels. The compact physical design measuring 150 x 116.5 x 53mm with a net weight of just 607 grams makes this charger portable enough for the RC track, field or pitch, yet substantial enough to feel robust and well-engineered. The inclusion of 4mm banana socket connectors and XH LiPo balancer ports means you'll have compatibility with the majority of battery types used in modern ready-to-run RC vehicles across the UK market.

Frequently Asked Questions

• Is the eTronix PowerPal 4.0 suitable for beginners in the RC hobby? — Yes, absolutely. Whilst the PowerPal 4.0 offers advanced features like individual cell monitoring and PC connectivity that appeal to experienced RC enthusiasts, the large LCD display, intuitive contactless key switch and automatic microprocessor management make it extremely easy for beginners to charge their batteries safely. Simply select your battery chemistry, cell count and desired charge current, and the charger does the rest.
• What charge current should I use for my LiPo battery? — Most LiPo batteries charge safely at a rate between 0.5-1.0C (where C = battery capacity in amps). For example, a 5000mAh battery charges safely at 2.5-5.0 amps. The PowerPal 4.0's range of 0.1-10.0A accommodates everything from small 1S batteries in RC aircraft to large capacity packs in high-performance RC cars. Always consult your battery manufacturer's recommendations for the specific charge rate.
• Can I use this charger for different battery types? — The eTronix PowerPal 4.0 supports multiple battery chemistries including LiPo, Li-ion, LiFe, NiCd, NiMH and lead-acid batteries, making it a genuinely universal charger. You can switch between chemistry types using the LCD menu, and the microprocessor automatically applies the correct charging profile for each battery type.
• How does the balancing function work on this charger? — The universal balancing port (2.54mm pitch) connects directly to your LiPo, Li-ion or LiFe battery's balance connector. During charging, the PowerPal 4.0 monitors each cell individually and delivers 200mA per cell to ensure all cells reach exactly the same voltage. This keeps your battery pack healthy, improves runtime and prevents the overcharging that can damage expensive battery packs.
• What's the difference between the PowerPal 4.0 and older PowerPal models? — The PowerPal 4.0 is the most powerful model in the range, with 200W maximum charge power and 10A maximum charge current, compared to lower-wattage models in the PowerPal series. This means faster charging times, especially for larger battery capacities and higher cell counts commonly used in modern RC cars and electric aircraft in the UK market.
• Do I need a PC to use this charger? — No, the PC link socket is entirely optional. The PowerPal 4.0 works perfectly as a standalone charger using just the LCD display and contactless key switch. The PC connection is for advanced users who want to access detailed charging logs, set up custom profiles or integrate the charger with more complex battery management systems.
• Can I charge my mobile phone whilst charging my RC batteries? — Yes, the built-in USB power socket provides convenient charging for phones, tablets and other USB devices. This is particularly useful at the RC track or field where you're managing multiple batteries and devices simultaneously.
