Technical Performance

The Gens Ace Redline 2.0 5100mAh 140C HV LiPo battery represents the pinnacle of modern power cell engineering for 1/10th scale RC car applications. With a 140C continuous discharge rating, this battery can safely deliver up to 714 amps of current (5100mAh × 140C), providing sufficient power for high-performance brushless motors rated for 2S LiPo systems, including sensored and sensorless variants. The 7.6V nominal voltage (2S HV configuration) delivers peak voltage that satisfies the maximum voltage specifications of modern brushless ESCs, though you must ensure your chosen ESC is rated for 2S LiPo and HV chemistry compatibility before installation. The battery's exceptional energy density means you're getting maximum performance per gram of weight, critical for RC car UK racing where every fraction of a second matters and vehicle weight directly impacts acceleration, deceleration, and top-speed potential. The stable automatic stacking technology and strict single-cell capacity matching ensure that both cells within the pack discharge identically throughout your run, preventing voltage imbalance that can cause ESC cutoff errors or premature low-voltage alarms. Gens Ace's engineering also enables stable simultaneous discharge, meaning the battery maintains consistent performance whether you're in a hard acceleration sprint or a sustained high-speed corner. The low internal resistance (IR) specification is crucial for performance: it means that even when drawing maximum current, voltage sag remains minimal, keeping your motor spinning at peak efficiency and your vehicle handling predictably throughout the entire run. The hard case exterior provides mechanical protection without adding significant bulk, using lightweight engineering that keeps the overall 190-gram weight competitive with similarly-specified soft-case alternatives. The 112.5 × 46.5 × 18.8mm dimensions fit standard 2S battery trays in most 1/10th scale touring cars, short course trucks, and stadium trucks without requiring modifications or custom mounting solutions.

Frequently Asked Questions

• What RC cars and trucks is the Gens Ace Redline 2.0 5100mAh battery compatible with? — This battery is specifically designed for 1/10th scale touring cars (TC), 1/10th scale short course trucks (SC), and other 1/10th scale RC vehicles with ESCs rated for 2S LiPo batteries. Popular compatible vehicles include competition-level touring cars, stadium trucks, and high-performance buggies. Always verify your specific vehicle's ESC voltage specification before purchase to ensure compatibility, as some older 2S vehicles may use standard LiPo rather than HV chemistry.
• Is the Gens Ace Redline 2.0 good for beginners? — While the battery itself is reliable and well-engineered, the 140C discharge rating and 5100mAh capacity make it better suited for experienced racers and serious weekend bashers rather than absolute beginners. Beginners typically start with more modest specifications like 50C or 80C batteries to learn proper LiPo handling, charging, and storage procedures. However, if you're a beginner with adult supervision or existing LiPo experience, this battery is perfectly safe provided you use a quality LiPo charger with balance charging capability and observe proper storage at storage voltage (around 3.8V per cell).
• How long does the Gens Ace Redline 2.0 take to charge? — Charge time depends on your charger's maximum current output and the charging rate you select. For a 5100mAh battery, charging at 5A (1C rate) takes approximately 60 minutes; at 10A (2C rate) takes approximately 30 minutes. Most modern balance chargers support charge rates up to 5C or higher, meaning you could charge this pack in 12-15 minutes at maximum safe rate. Always read your specific charger's manual and never exceed the battery's stated maximum charge current.
• What is the difference between this HV battery and standard 2S LiPo batteries? — HV (High Voltage) LiPo cells have a slightly higher chemistry that allows them to charge to 4.35V per cell (8.7V pack voltage) compared to standard LiPo's 4.2V per cell (8.4V pack). This extra 0.3V per cell provides approximately 7% more energy capacity and performance headroom, though it requires an HV-compatible charger to charge safely. The Gens Ace Redline 2.0 HV chemistry also maintains voltage stability better during high-discharge scenarios, which is why it's preferred for high-C rated applications like competition RC car racing.
• Does the battery come with a charger? — No, the Gens Ace Redline 2.0 battery does not include a charger. You will need to purchase a separate LiPo charger that supports 2S LiPo batteries and HV charging profiles. Most modern chargers include these capabilities, and quality options range from budget-friendly to professional-grade race chargers with advanced monitoring.
• What connector type is included? — The battery features factory-installed 5.0mm bullet connectors (also called 5mm bullet connectors or 5mm tubes), which are the industry standard for RC cars and trucks. These connectors are widely available as replacement parts and are compatible with most modern brushless ESCs designed for RC car applications.
• How much does this battery weigh and will it fit in my RC car? — The battery weighs approximately 190 grams with dimensions of 112.5mm length, 46.5mm width, and 18.8mm height. These dimensions fit within standard 2S battery trays in most 1/10th scale RC cars without modification. Measure your vehicle's battery compartment before ordering to confirm fit, particularly if you have a compact or heavily modified chassis.
