The pre-soldered 12 AWG silicone wires (approximately 100mm length) are ready to connect directly to your ESC without requiring additional soldering or modifications.
• Premium Cell Grading and Balancing — Each individual cell undergoes meticulous balancing, aging, grading, and matching based on voltage and internal resistance before assembly. This stringent quality control guarantees that only the highest-grade cells, with minimal tolerances between individual units, are used in your battery pack.
• Up to 3C Charge Rate Capability — You can charge this battery at rates up to 3C (20.1A), which means a full charge from empty can be achieved in approximately 20 minutes using a quality LiPo charger. This rapid recharge capability is essential for race day when you need quick turnaround between heats and practice sessions.
• JST-XH 4S Balance Connector — The standard JST-XH four-cell balance connector allows safe, precise cell balancing using any modern LiPo charger with balance charging capability. This feature ensures each of the four cells maintains equal voltage, maximising battery life and preventing over-charging of individual cells.
• Compact Dimensions and Lightweight — At 138mm length, 47mm width, and 45mm thickness, this battery fits efficiently into most 1/10 scale RC car battery trays. The lightweight design (550g without wires) minimises added weight to your chassis, preserving the vehicle's handling characteristics and acceleration response.
• Extended Lifespan Through Quality Manufacturing — The combination of premium cell selection, precise matching, and rigorous quality assurance processes results in extended life and cycle times compared to standard hobby batteries. You can expect this battery to maintain performance and reliability through hundreds of charge cycles when properly maintained.

Frequently Asked Questions

• What does the 50C discharge rate mean and why does it matter for RC cars? — The 50C rating means this battery can safely deliver 50 times its capacity (6700mAh = 6.7Ah) continuously without damage. In practical terms, this allows 335A of continuous current delivery, which powers the high-performance brushless motors found in competitive RC cars. A higher C rating means quicker acceleration, better throttle response, and more consistent power delivery throughout your race run, which is why serious racers choose 50C batteries over lower-rated alternatives.
• Is this battery suitable for beginners or only experienced racers? — Whilst this battery is engineered for high-performance racing applications, beginners can use it safely provided they understand basic LiPo battery safety procedures including proper charging with a compatible charger, avoiding over-discharging, and storing in a safe location. Beginners should ensure they use a quality LiPo charger with balance charging capability and consider using a LiPo alarm to monitor battery voltage during use. The investment in a premium battery like this actually makes sense for beginners as it will last longer and maintain performance more consistently than budget alternatives.
• What 1/10 scale RC cars are compatible with a 4S 14.8V battery? — This 4S LiPo battery is compatible with virtually all modern 1/10 scale electric RC cars including competitive racing buggy bodies, stadium trucks, short course trucks, and touring car platforms. Compatibility depends on your vehicle having a standard ESC (Electronic Speed Controller) rated for 4S LiPo battery systems. Check your vehicle's specifications or ESC manual to confirm 4S compatibility before purchase, as some entry-level models may only support 2S or 3S batteries.
• How long will this battery last on a single charge? — Runtime depends on your vehicle's motor, ESC settings, driving style, and terrain. Typical runtime ranges from 12 to 25 minutes of aggressive racing or bashing, with longer duration possible at reduced throttle. The 6700mAh capacity is well-suited to 1/10 scale cars where 15-20 minute race heats are standard, allowing you to complete a practice session or competitive heat on a single charge.
• What's the difference between the Power Racing 50C and the Sport Racing 60C versions? — The Power Racing 50C offers a continuous discharge rate of 50C with 6700mAh capacity, whilst the Sport Racing 60C variant provides 60C continuous discharge and slightly higher 6900mAh capacity. The 60C version delivers marginally higher current and slightly more energy, making it optimal for maximum performance racing where every advantage counts. The 50C version offers excellent performance at slightly lower cost, making it an outstanding choice for serious enthusiasts who want premium quality without the expense of the top-tier 60C model.
• How should I charge this battery safely? — Always use a quality LiPo battery charger with balance charging capability, set to 3C charge rate maximum (20.1A for this battery). Connect both the main XT90 connector and the JST-XH balance connector to your charger. Balance charging ensures all four cells maintain equal voltage, which is critical for battery longevity. Never leave a charging battery unattended, never charge in damp conditions, and consider using a LiPo charging bag as an extra safety precaution. Refer to the multilingual safety documents provided with your battery for detailed charging procedures.
• What is the weight of this battery and will it fit my RC car? — The battery weighs approximately 550g without wires and measures 138mm length × 47mm width × 45mm thickness. These compact dimensions fit standard battery trays in most 1/10 scale RC cars. The lightweight design minimises impact on your vehicle's centre of gravity and weight distribution, which is important for maintaining handling characteristics. Check your specific vehicle's battery compartment dimensions to ensure compatibility before purchasing.
• Can I use this battery with my existing RC car charger? — This depends on your charger's specifications. The battery requires a LiPo charger capable of handling 4S batteries and ideally supporting up to 3C charge rates (20A+). Many modern LiPo chargers are multi-chemistry and support 4S systems, but if your charger only supports 2S or 3S batteries, you will need to upgrade to a compatible 4S-capable charger. This is a worthwhile investment as quality LiPo chargers are reliable, affordable, and compatible with all future 4S batteries you may purchase.
