Technical Performance

The GENSACE Li-Po G-Tech battery represents the pinnacle of compact battery design for mini-scale RC vehicles. With a 7.4V nominal voltage delivered by two LiPo cells in series (2S1P configuration), this battery provides the electrical performance characteristics expected from modern LiPo technology. The 1700mAh capacity is precisely calibrated for 1/18-scale vehicles like the Arrma Grom range, offering the ideal compromise between runtime and weight. The 35C continuous discharge rating means the battery can safely deliver up to 59.5 amps of current (1700mAh × 35C = 59,500mA), which is more than sufficient for both brushed and brushless motors commonly found in mini-scale vehicles. The battery's dimensions of approximately 100 × 30 × 20mm and weight of 95 grams fit perfectly within the battery compartments of Arrma 1/18 mini-scale models, ensuring proper fitment without requiring case modifications or spacers. The hardcase construction uses durable materials that protect the cells whilst remaining lightweight, a critical engineering consideration for competitive RC driving. Gens Ace manufactures this battery to ISO9001 and ISO14001 standards, ensuring quality control and environmental responsibility throughout the manufacturing process. The low internal resistance (IR) of the G-Tech cells ensures stable voltage delivery right up until the battery reaches its safe operating limit, which means your mini-scale RC car performs consistently throughout the entire battery run.

Frequently Asked Questions

• Is the GENSACE G-Tech 1700mAh battery suitable for my Arrma Grom series RC car? — Yes, absolutely. This battery is specifically designed for the Arrma Grom series including the Granite Grom, Typhon Grom, Mojave Grom, Gorgon Grom, Quake Grom, and the 1/16 Mini Kraton. The iEC2 connector matches the original equipment connectors perfectly, and the compact dimensions and weight are optimised for these mini-scale vehicles. The battery is also compatible with Losi NASCAR mini-scale vehicles and other mini-scale RC cars using EC2 or IC2-style connectors.
• How long will this battery run for on a single charge? — The exact runtime depends on your specific vehicle setup, driving style, and terrain, but the 1700mAh capacity offers significantly longer run times compared to smaller 500-1000mAh packs typically found in budget mini-scale vehicles. Most users report extended driving sessions lasting 20-30 minutes or more with this capacity, though aggressive performance driving may reduce run time. We recommend having at least two batteries on hand to maximise your driving time during an RC session.
• What makes the iEC2 connector different from standard EC2 connectors? — The iEC2 is Gens Ace's proprietary improved connector design that offers enhanced compatibility with original equipment connectors found on Arrma vehicles. Whilst the iEC2 matches EC2 and IC2 device connectors, the iEC2 design includes integrated reverse polarity protection, preventing accidental reverse connection that could damage your RC car's electronics. This makes it a safer, more reliable option than generic aftermarket connectors.
• Can I use this battery with a brushless ESC in my mini-scale RC car? — Yes, the 7.4V 2S LiPo battery is fully compatible with brushless electric speed controllers designed for 2S LiPo batteries, which are the standard in the mini-scale RC market. The 35C discharge rating provides more than sufficient current delivery for typical brushless setups in 1/18-scale vehicles. However, always verify that your specific brushless ESC is rated for 2S LiPo operation before connecting any battery.
• How should I store and maintain this LiPo battery? — LiPo batteries should always be stored in a cool, dry location away from direct heat or cold extremes. When storing for extended periods, charge the battery to approximately 50% capacity (storage voltage around 3.7V per cell) rather than leaving it fully charged or fully depleted. Always inspect the hardcase for signs of damage before use, and never use a battery that shows visible swelling, cracks, or other damage. Follow proper LiPo charging procedures using a dedicated LiPo charger with balance charging capability.
• What is the difference between this battery and other 2S 1700mAh packs available in the UK RC market? — The GENSACE G-Tech stands out through several key differentiators: the patented iEC2 connector with reverse polarity protection, the hardcase construction for durability, and Gens Ace's reputation for manufacturing high-quality LiPo batteries with consistent performance and low internal resistance. The ISO9001 and ISO14001 certifications indicate quality manufacturing standards. Additionally, this battery is specifically engineered for mini-scale vehicles rather than being a generic pack adapted from larger vehicle applications, meaning the dimensions, weight, and connector type are optimised for your Arrma Grom or similar mini-scale RC car.
• Is this battery safe for beginners? — LiPo batteries require responsible handling and proper charging procedures, so beginners should familiarise themselves with LiPo safety guidelines before using any LiPo battery. However, the hardcase construction and iEC2 reverse polarity protection make this battery safer than soft-pack alternatives. The key to safe LiPo operation is always using a proper LiPo charger with balance charging, never overcharging the battery, and regularly inspecting it for damage before and after use.
• What charging equipment do I need? — You'll need a dedicated LiPo charger with balance charging capability. The iEC2 connector on this battery is compatible with chargers equipped with standard EC2 or IC2 charging ports, or you may use an adapter cable if your charger uses a different connector type. We recommend a quality charger from brands like Hobbywing or Spektrum to ensure safe, efficient charging and maximum battery lifespan.
