Technical Performance

The VOLTZ 4000mAh 2S 7.4V 50C Hardcase LiPo Battery delivers genuine technical performance characteristics backed by straightforward, honest specifications. The 4000mAh capacity combined with the 2S cell configuration produces a nominal voltage of 7.4V, which is the standard power requirement for the vast majority of ready-to-run RC cars available in the UK market, from brushed entry-level vehicles to modern brushless systems. The continuous discharge rating of 50C means this battery can safely deliver up to 200 amps of continuous current (4000mAh × 50C = 200A), providing abundant power for typical 1/10-scale RC vehicles with sensible ESC ratings. The maximum burst discharge rating of 100C enables the battery to handle brief periods of very high current draw, such as during aggressive acceleration or climbing steep obstacles, without significant voltage sag or performance degradation. The hardcase construction distinguishes this battery from cheaper soft-case alternatives, as the rigid plastic shell absorbs impacts and vibrations that would otherwise stress the lithium polymer cells themselves. The dimensions of 138 × 46 × 25 mm represent a compact stick-pack profile that fits into the majority of battery compartments on popular entry-level vehicles, though dimensions should always be verified against your specific vehicle's battery bay before purchasing. The Deans/T plug connector is the industry standard for RC car batteries in the UK and Europe, offering excellent conductivity and secure connections. With 29.6 watt-hours of stored energy, this represents a genuine mid-capacity option suitable for typical weekend RC sessions without requiring an excessive number of battery packs for a full day's use.

Frequently Asked Questions

• Is this battery suitable for entry-level RC car owners and beginners? — Yes, absolutely. This VOLTZ hardcase battery is specifically designed for entry-level ready-to-run RC cars and bashing applications. The 2S configuration is the most common voltage for beginner-focused vehicles, and the 4000mAh capacity provides adequate runtime for typical RC sessions. The hardcase construction also makes this battery more forgiving of the occasional knock or impact that often happens when learning to drive. Many RC enthusiasts recommend starting with 2S LiPo batteries like this one before progressing to higher-voltage options.
• What charge rate should I use for this 4000mAh battery? — The recommended charging rate is typically 1C, which for a 4000mAh battery equals 4 amps. However, if your charger only offers fixed settings such as 1, 3, and 5 amps, then 3 amps is the safer choice and will deliver a slower but equally effective charge. Avoid charging at 5 amps unless specifically recommended by your charger manufacturer, as this exceeds the safe 1C rate. Always ensure your charger has a dedicated 2S LiPo balance charging port, and never use a charger designed solely for NiMH batteries.
• Which RC vehicles is this battery compatible with? — This battery is suitable for a wide variety of popular entry-level RC cars that accept 2S stick-pack LiPo batteries with Deans/T connectors, provided the battery bay dimensions accommodate the 138 × 46 × 25 mm form factor. Known compatible vehicles include FTX Vantage, FTX Outback Fury Xtreme, FTX Bugsta, Traxxas Rustler 2WD (in LiPo mode), HPI Savage Flux series, Team Associated RB10, Maverick Strada (with caveats), and many similar models. However, some vehicles require the ESC to be placed into LiPo mode via programming or jumper adjustment before use. Always verify physical dimensions and voltage requirements for your specific vehicle before purchasing, and check the manual for LiPo compatibility instructions.
• Do I need an adapter to use this battery with my charger? — Most modern LiPo chargers feature a Deans connector port, so this battery will plug directly into your charger without adapters. However, some older or basic chargers may only feature Tamiya or other connectors. The balance charging connector on this battery is a standard 2S balance plug, which fits the majority of balance charging ports on 2S/3S/4S capable chargers. If your charger lacks a Deans port, you can use a simple Deans-to-[your charger type] adapter lead.
• How long will this battery last in terms of charge cycles? — LiPo batteries typically maintain good performance for 150-300 full charge cycles, though this varies based on charging practices, storage conditions, and usage patterns. To maximise lifespan, always avoid fully discharging the battery to zero (most RC ESCs have low-voltage cutoff), store the battery at around 50% charge between sessions, keep it cool, and avoid physical damage. The hardcase design on this battery helps protect the cells and can contribute to longer overall lifespan compared to soft-case packs.
• Can I use this battery in a vehicle originally designed for NiMH batteries? — Most vehicles designed for NiMH batteries can accept 2S LiPo batteries, but the ESC must support LiPo mode or the voltage will cause damage. Check your vehicle's manual or ESC documentation to confirm LiPo compatibility. If your vehicle supports LiPo, you may need to adjust a jumper on the ESC or reprogram it via computer software to enable LiPo mode. Consult the ESC manual or contact the manufacturer if you're unsure about compatibility.
• What is the difference between the 50C continuous and 100C burst discharge ratings? — The 50C continuous rating means this battery can safely deliver 200 amps continuously throughout your driving session without damage (4000mAh × 50C = 200A). The 100C burst rating means it can briefly handle double that current during sudden acceleration spikes or obstacles, typically for seconds at a time. Both ratings are safe and normal operating parameters for LiPo batteries; the burst rating simply describes the battery's ability to respond to sudden demands without voltage sag.
• Does this battery come with a charger? — No, this is a battery pack only and does not include a charger. You will need to purchase a compatible LiPo charger separately. Popular options suitable for 2S LiPo batteries include the Skyrc T100, the Tenergy TLP-6000, and similar balance chargers available from RC retailers across the UK.
• What is the runtime I can expect from this battery? — Runtime varies significantly depending on your vehicle's motor, ESC, driving style, terrain, and throttle usage. A general guideline suggests 20-40 minutes of moderate driving, but aggressive bashing or racing will reduce this, whilst gentle cruising may extend it. Rather than relying on estimated runtime, it's best to simply monitor your first few sessions with this battery and observe how long it lasts in your specific vehicle and driving conditions.
• Can I charge this battery overnight or leave it unattended on the charger? — No, LiPo batteries should never be left unattended whilst charging. Always supervise charging, place the battery in a LiPo charging bag or safety container, charge in a well-ventilated area, and never charge near flammable materials. Most LiPo chargers include automatic shutoff once charging is complete, but the safest practice is to remain present and monitor the charge process.
