Technical Performance

The GENSACE G-Tech battery represents the pinnacle of lithium polymer battery engineering for demanding RC applications. At 5000mAh capacity with a 4S (14.8V) configuration, this battery delivers substantial energy reserves specifically calibrated for 1/7 and 1/8 scale RC cars, helicopters, and FPV platforms. The 45C continuous discharge rating means this battery can safely deliver 225 amps of current continuously (5000mAh × 45C = 225A), with burst capacity reaching 90C for peak power demands during acceleration and aggressive flight manoeuvres. Weighing approximately 462 grams with dimensions of 155mm length × 46mm width × 30mm height, the battery maintains a compact profile suitable for most modern RC vehicle battery compartments whilst delivering exceptional energy density. The recommended charging rate of 1-3C (with a 5C maximum) ensures safe, efficient charging that preserves cell longevity—at 1C, you'd charge at 5 amps for one hour, whilst 3C charging would complete in approximately 20 minutes. The low internal resistance (IR) characteristic ensures stable voltage delivery until the battery reaches the end of its discharge cycle, maintaining consistent power delivery for reliable RC performance. This engineering excellence is underpinned by Gens Ace's ISO9001 and ISO14001 certifications, guaranteeing manufacturing standards and environmental responsibility. The advanced stacking technology represents years of specialised high-power battery development, enabling capacities previously thought impossible at this weight ratio, making it an essential choice for competitive racing and demanding flight applications across the RC hobby community in the UK.

Frequently Asked Questions

• What RC models is the GENSACE G-Tech 5000mAh battery compatible with? — This battery is specifically designed for 1/7 and 1/8 scale RC cars, helicopters, and FPV platforms. Confirmed compatible models include the Traxxas Sledge, Mikado Logo 500, Align T-Rex 550/600, Gaui X5, Outrage 550, Hirobo SDX, and various FPV systems. Always verify your specific RC model's battery requirements before purchase to ensure proper fit and electrical compatibility.
• How long will the GENSACE G-Tech battery last per charge? — Runtime depends on your RC model's discharge rate and driving style. The 5000mAh capacity with 45C discharge capability provides substantial flight or run time, though exact duration varies. For reference, a vehicle drawing 100 amps continuously would consume the full battery in approximately 3 minutes, whilst lighter loads extend runtime proportionally. Most RC enthusiasts experience 15-25 minutes of typical use per charge depending on application.
• What charger should I use with this battery? — The GENSACE G-Tech is optimised for G-Tech supported chargers, which use the Auto Charge Technology to automatically detect and set charging parameters through the built-in ID chip. However, the battery remains fully compatible with standard general purpose LiPo chargers, where you'll need to manually programme the charge rate. We recommend charging at 1-3C (5-15 amps) for optimal battery longevity, though 5C maximum (25 amps) charging is supported.
• Is the GENSACE G-Tech suitable for beginners? — Whilst this is a high-quality battery, it's best suited to experienced RC enthusiasts who understand LiPo battery safety and handling. Beginners should start with ready-to-run RC kits that include matched batteries and appropriate chargers. However, if you have experience with LiPo batteries, the G-Tech's smart connector technology actually makes it safer and easier to use because Auto Charge Technology prevents programming errors on compatible chargers.
• What does the 45C discharge rating mean? — The 45C rating indicates this battery can continuously discharge 45 times its capacity in amps (5000mAh × 45C = 225 amps maximum). The 90C burst rating allows short-term peaks at 450 amps for acceleration and demanding manoeuvres. These high discharge ratings make this battery ideal for racing and performance-oriented RC applications that demand rapid power delivery.
• How does the G-Tech ID chip improve charging safety? — The integrated ID chip stores critical battery data including cell chemistry, exact capacity, and recommended charge parameters. When used with G-Tech supported chargers, this information is automatically read, allowing the charger to configure itself correctly without user input. This eliminates dangerous programming mistakes and ensures optimal charging every single time.
• What is the difference between the EC5 connector and other battery connectors? — The EC5 connector is a heavy-duty battery connector rated for high current applications, perfect for the 225-amp capability of this battery. EC5 connectors provide secure, reliable connections that don't suffer voltage drop under high current, unlike lighter XT60 or XT90 connectors. The factory-fitted EC5 means your battery is ready to connect to any compatible RC vehicle without additional adapter cables.
• Can I use this battery with my existing RC charger? — Yes, the GENSACE G-Tech maintains full compatibility with standard LiPo chargers. However, you'll need to manually set the charge parameters (voltage: 14.8V for 4S, charge rate: 1-3C recommended). With a G-Tech supported charger, the ID chip eliminates this manual step, making charging automatic and foolproof.
• What does the soft case do and is it necessary? — The protective soft case shields your battery from physical damage during transport and storage, preventing impacts from damaging the delicate cell structure. Whilst not essential for operation, it significantly extends battery lifespan by protecting against external damage and is invaluable for serious RC enthusiasts who want to protect their investment.
• How should I store this battery when not in use? — For optimal longevity, store the GENSACE G-Tech battery at approximately 50% state of charge (roughly 3.85V per cell, or 15.4V for this 4S pack) in a cool, dry location. If storing for extended periods, recharge to the 50% level every 2-3 months. Avoid storing fully charged or fully discharged, as both conditions stress the cells and reduce overall lifespan.
