RDNA0104

Overview

The Radient NiMH 8.4V 5000mAh SC 6-1 Hump battery pack with Deans (HCT) connector is a robust and dependable power solution for RC enthusiasts across the UK looking to upgrade their surface models. This high-capacity nickel-metal hydride battery is specifically designed for 1/10 and 1/19 scale RC cars and trucks that require reliable, consistent power delivery. Whether you're a seasoned RC car UK competitor or a weekend basher, this 7-cell pack provides the performance boost needed to extend your running time and enhance your RC experience without the complexity of LiPo charging systems.

Built on proven NiMH technology, the Radient RDNA0104 is an excellent choice for those looking to replace older battery packs or upgrade from smaller 6-cell configurations. The 8.4V rating delivers noticeably better performance than standard 7.2V NiMH batteries, making your RC vehicle quicker and more responsive whilst maintaining the ease of use that NiMH batteries are known for. This is an ideal battery for Helion models including the Criterion, Dominus 10SC, Dominus 10SCv2, Dominus 10TR, Intrusion 10MT and Volition 10SC, though it is compatible with many other surface models featuring SC-size battery compartments.

As a practical solution for UK RC enthusiasts, this battery combines high capacity with a compact form factor. The distinctive 6-1 hump configuration places slightly more material in the centre of the pack to achieve the 5000mAh capacity whilst keeping the overall length and width dimensions standard for NiMH stick packs. This makes it an excellent upgrade option for models that already accommodate hump-style batteries, offering significantly extended run times compared to smaller capacity packs without requiring a complete vehicle redesign.

Technical Performance

The Radient NiMH 8.4V 5000mAh SC 6-1 Hump battery pack represents a mature evolution of nickel-metal hydride technology, engineered to deliver consistent performance in demanding RC surface applications. The seven Sub-C cells are precision-matched and configured in series to produce a stable 8.4V output, providing the voltage boost that modern brushed and brushless speed controllers require for optimal performance. The 5000mAh capacity is particularly impressive for a hump-style pack, offering run times typically 20-30% longer than standard 4500mAh alternatives. The battery's construction utilises high-quality cell chemistry that maintains voltage stability even under the high discharge rates typical of competitive RC racing and aggressive bashing. The Deans (HCT) T-style connector features a secure fit and low-resistance design that minimises voltage drop during high-current draws, ensuring your ESC receives clean, stable power. With a weight of 520 grams, the battery strikes an excellent balance between capacity and mass, suitable for 1/10 and 1/19 scale vehicles. The 6-1 hump configuration is engineered to fit within standard battery braces on compatible vehicles, though the raised central section may conflict with some battery retention systems, making it essential to verify your vehicle's specific compatibility before purchasing. NiMH batteries charge reliably with standard NiMH chargers and exhibit no memory effect, allowing flexible charging schedules without performance degradation. The black colour housing is durable and designed to withstand typical RC use including minor impacts and vibration.

Frequently Asked Questions

• Is the Radient RDNA0104 battery compatible with my Helion Volition? — Yes, the Radient 8.4V NiMH battery pack is specifically listed as compatible with the Helion Volition 10SC. However, you should consult your vehicle's manual to ensure the battery brace can accommodate the 6-1 hump design, as the raised centre section may cause fitment issues with some battery retention systems.
• Will this battery make my RC car faster? — The speed improvement depends on your vehicle's standard battery voltage. If your RC car currently uses a 7.2V battery, upgrading to this 8.4V pack will make it noticeably quicker, as the additional voltage provides increased motor speed and acceleration. However, if your vehicle already comes equipped with an 8.4V battery like the Criterion, the speed will remain the same, though runtime will be significantly longer due to the higher 5000mAh capacity compared to smaller stock packs.
• Can I use this battery with a LiPo charger? — No, this is a nickel-metal hydride battery and must be charged with an NiMH-compatible charger. Using a LiPo charger designed for lithium polymer batteries could damage the battery or create safety hazards. Always use a charger specifically rated for NiMH batteries.
• How does the 6-1 hump configuration affect my vehicle? — The 6-1 hump places slightly more material in the centre of the battery pack to achieve the 5000mAh capacity whilst keeping standard length and width dimensions. This design fits within the battery compartments of many RC models, but the raised centre may conflict with battery braces in some vehicles. Always check your owner's manual before purchase to ensure the hump design won't interfere with your vehicle's battery retention system.
• Is this suitable for beginners? — Yes, NiMH batteries like this Radient pack are excellent for beginners because they are forgiving to charge, require no special safety precautions like LiPo batteries, and offer reliable performance. The 8.4V rating provides noticeable performance improvements, making it a worthwhile upgrade from stock batteries without the complexity of managing lithium polymer batteries.
• What is the difference between this 8.4V battery and a standard 7.2V battery? — The additional 1.2 volts in an 8.4V pack comes from having seven cells instead of six. This extra voltage translates to noticeably faster acceleration and higher top speed in compatible vehicles. The 8.4V configuration is also lighter than packing extra capacity into a 7.2V battery, making it an efficient upgrade option. However, your speed controller must be rated for 8.4V operation; some older ESCs designed only for 7.2V may not be compatible.
• How long will this battery last compared to smaller packs? — The 5000mAh capacity is significantly larger than typical stock batteries, which usually range from 2200mAh to 3300mAh. You can expect 40-60% longer run times compared to standard capacity packs, though actual duration depends on your driving style, vehicle weight, motor efficiency and terrain conditions.
• Does the battery come with a charger? — No, this is a battery pack only. You will need to purchase an NiMH charger separately that is rated for 8.4V and Sub-C cell batteries. Many quality NiMH chargers are available from RC hobby retailers across the UK.
