Key Features

• 5000mAh Capacity — This substantial capacity delivers extended runtime during your RC sessions, allowing you to spend more time driving and less time charging between batteries. The 5000mAh capacity provides sufficient power for extended bashing, racing and competitive runs across all RC vehicle types.
• 11.1V 3S Configuration — The three-cell (3S) lithium polymer design delivers 11.1V nominal voltage, providing the perfect balance of power and efficiency for standard RC vehicles. This voltage rating is widely compatible with most mid-range brushless RC cars, trucks and buggies available in the UK market today.
• 50C Maximum Continuous Discharge Rate — This high discharge rate ensures you get punchy, consistent power throughout your driving session, with the battery capable of delivering sustained current without voltage sag. The 50C rating means this pack can comfortably handle high-demand brushless motors and racing setups, maintaining performance even under heavy load.
• Hard Shell Case Construction — The protective hard case shell shields the delicate lithium polymer cells from impacts, crashes and general wear during demanding runs. This rugged construction protects your investment and ensures longevity, reducing the risk of cell damage that can occur with soft pack batteries during aggressive driving.
• Low Profile Stick Pack Design — The compact stick pack form factor (139 x 47 x 39mm) fits into tight battery compartments in modern RC vehicles, making this battery compatible with a wide range of RTR models and race-ready setups. The low profile dimensions ensure proper weight distribution and don't compromise your RC car's handling characteristics.
• Pre-Fitted EC5 Output Connector — The standard EC5 connector comes pre-installed, eliminating the need for soldering or connector swapping. This means instant plug-and-play convenience, allowing you to get straight to driving without technical preparation, making it perfect for both beginners discovering RC cars for the first time and experienced racers.
• Strain Relief Balance Cable Clip — A protective strain relief clip has been thoughtfully included to protect the delicate balance connector cables from damage. This prevents one of the most common causes of battery failure, extending the service life of your expensive LiPo pack through multiple seasons of use.
• 55.5 Watt Hour Rating — This energy specification demonstrates the total power available, translating to reliable, sustained performance throughout your driving session without voltage drop-off that compromises acceleration and responsiveness.

Technical Performance

The Voltz 5000mAh hard case stick pack represents a carefully engineered balance between performance, protection and value. With a maximum continuous discharge rate of 50C, this battery is more than capable of powering modern brushless RC cars, trucks and racing machines that demand high current delivery. The hard shell case construction uses robust materials to create a protective barrier around the three lithium polymer cells, whilst maintaining the compact dimensions (139mm length × 47mm width × 39mm height) necessary for tight battery compartments. The engineering is straightforward but effective—quality cells selected by one of the world's leading battery manufacturers, wrapped in protective plastic casing, and fitted with proven EC5 connectors that provide reliable electrical connection and disconnection. The balanced approach to design means you get genuine durability without excessive weight penalty, crucial for RC vehicles where battery weight directly impacts performance, acceleration and handling. The 11.1V nominal output of this 3S pack makes it compatible with the vast majority of standard brushless RC cars in the UK market, whilst the 55.5 watt-hour capacity ensures extended runtime for both casual weekend bashers and serious club competitors. Build quality is evident throughout, from the proper 10 AWG gauge wiring on the main leads to the included strain relief clip that protects balance connectors—these are details that matter when you're investing in proper equipment.

Frequently Asked Questions

• Will this battery work with my ARRMA RC car? — Yes, this 11.1V 3S hard case battery is compatible with many ARRMA vehicles including the Granite, Senton and Kraton models, provided your vehicle has an EC5 connector and can accommodate the 139 x 47 x 39mm dimensions. The Senton 4x4 3S and Granite v3 have been confirmed compatible by users. However, some newer ARRMA models use different connectors, so we recommend checking your manual or contacting our team to confirm compatibility with your specific model before purchasing.
• What is the difference between this hard case battery and a soft pack LiPo? — Hard case LiPos feature a protective plastic shell around the cells, providing superior protection against impacts and cell damage during crashes and aggressive driving. Soft pack batteries are lighter but more vulnerable to punctures and damage. For RC cars driven to their extremes, hard case packs like this Voltz battery offer better longevity and reliability, justifying the slight weight increase for most drivers.
• Is this suitable for brushless RC cars and trucks? — Absolutely. This battery is specifically designed and recommended for brushless RC vehicles. The 50C discharge rate means it can comfortably handle the high current demands of brushless motors, making it ideal for upgraded brushless setups and competition racing. If your brushless vehicle was supplied as ready to run without a battery, this is exactly the type of pack you need.
• How long will this battery last before needing replacement? — With proper care and charging practices, quality LiPo batteries like this Voltz pack can provide hundreds of charge cycles before significant degradation. Regular maintenance, avoiding complete discharge, and storing at proper voltage between use will maximise lifespan. Most users find LiPo batteries remain effective for 2-3 seasons of regular use.
• Can I use two of these batteries together? — Two of these packs can physically fit in larger RC vehicles like the ARRMA Kraton, though your vehicle must have sufficient battery tray space and appropriate wiring to run dual batteries in series or parallel. We recommend confirming your specific vehicle's compatibility and consulting our team for proper installation guidance.
• Is this battery suitable for club racing and competition? — Yes, the Voltz range has been specifically developed for club racers and competitive use. The consistent 50C discharge, hard case protection, and reliable performance make this an excellent choice for serious racers who need dependable power without premium pricing.
• What connector type does this battery have? — This model features the EC5 connector as standard, which is widely used across modern RC vehicles. The balance connector is JST-XH type, which is the industry standard for battery management.
