Key Features

• Deans T-Plug Connector — The Deans T-Plug (also known as HCT connector) is one of the most widely recognised and popular connectors in the RC hobby, ensuring simple and secure connectivity with compatible models and chargers, reducing the risk of accidental disconnection during use.
• Li-Ion Chemistry — Unlike traditional LiPo batteries, the Li-Ion technology in this pack provides superior cycle life, inherent safety features, and consistent voltage delivery throughout the discharge cycle, making it a brilliant choice for enthusiasts who prioritise reliability and longevity.
• Low Self-Discharge Rate — The lightweight Li-Ion chemistry offers exceptionally low self-discharge characteristics, meaning your battery retains its charge far longer when stored, so your RC model is always ready to blast off whenever you fancy a session at your local RC track or bashing spot.
• Compact Short Format Design — At just 52 x 37 x 19mm and weighing only 77 grams, this short battery is engineered to fit into tight spaces and chassis configurations where conventional longer packs simply won't work, giving you more vehicle compatibility options.
• XH Balance Connector — The integrated balance connector allows you to monitor and maintain optimal cell voltage balance during charging, extending battery lifespan and ensuring safe operation with compatible balance chargers.
• 7.4V Two-Cell Configuration — The 2S (two-series cell) voltage of 7.4V provides the ideal power balance for lighter RC vehicles and accessories, delivering sufficient punch without excessive strain on electronic components.
• 1500mAh Capacity — This 1500mAh capacity offers respectable runtime for recreational and casual racing applications, providing extended play sessions without the excessive weight penalty of higher-capacity packs.

Technical Performance

Frequently Asked Questions

• Is the Voltz 7.4V 1500mAh battery suitable for beginners and casual RC users? — Absolutely. This battery is purpose-built for everyday bashing, trail driving, and casual recreational use. The Li-Ion chemistry is inherently safer than LiPo alternatives, featuring built-in protection against common issues like over-discharge and overcharge. Beginners appreciate the straightforward Deans T-Plug connector and the low self-discharge characteristics, which mean the battery stays ready to use even if you take a break between sessions. The compact size also means it's less intimidating than larger packs, making it ideal for users new to the RC hobby.
• What is the difference between Li-Ion and LiPo batteries for RC use? — Li-Ion batteries offer several advantages over traditional LiPo packs. They have superior cycle life, meaning they maintain performance over many more charge-discharge cycles, reducing your long-term costs. Li-Ion packs are inherently safer, with built-in protection circuits that prevent dangerous conditions like over-charge and over-discharge. They feature significantly lower self-discharge rates, so your battery retains its charge much longer during storage. The trade-off is that Li-Ion packs typically deliver slightly lower peak discharge rates compared to high-performance LiPo alternatives, but for recreational use, trail driving, and casual bashing, this is rarely a limitation.
• Which RC models are compatible with the Voltz 7.4V 1500mAh battery? — The manufacturer specifically recommends this battery for the FTX Tracer and BlackZon Slyder. However, because it features the ubiquitous Deans T-Plug connector, it's compatible with any RC vehicle equipped with this connector type. Before purchasing, always check your model's specifications to confirm it accepts 7.4V power and features a Deans connector. Using the correct voltage is essential for safe operation and protecting your model's electronic components.
• How long does it take to charge the Voltz 7.4V 1500mAh battery? — Charge time depends on your charger's output capacity and whether you're performing a standard or balance charge. Generally, with a typical RC charger, you can expect full charge times ranging from 1-3 hours. Always follow your charger manufacturer's instructions and never exceed the maximum charge current specifications to ensure safe operation and maximum battery lifespan.
• What makes the short battery format better than standard-length batteries? — The compact short format design offers superior versatility for RC vehicles with limited battery bay space. Many modern RC models, particularly smaller scales and specialised designs like the FTX Tracer, benefit from batteries that don't consume excessive chassis real estate. The reduced length also improves weight distribution and can enhance handling characteristics. If your model's manual specifies a short-format battery, the Voltz 7.4V 1500mAh short pack is an ideal choice.
• Is this battery waterproof for wet weather RC use? — Whilst the battery pack itself has durable soft-case construction, it's not explicitly rated as waterproof. However, the Deans T-Plug connector is generally splash-resistant. For wet weather use, we recommend checking your specific RC model's water-resistance specifications, as the battery's performance in wet conditions depends largely on your vehicle's overall waterproofing. If your model features waterproofed electronics, the battery should function adequately in light rain or spray conditions, though we always recommend proper drying after wet use.
• How do I properly care for and store the Voltz Li-Ion battery? — Store your battery in a cool, dry place at room temperature, ideally between 15-25 degrees Celsius. The low self-discharge characteristics mean you can store it fully charged without significant capacity loss. Before extended storage lasting more than a month, consider storing at approximately 50% charge to maximise long-term lifespan. Always inspect the battery for physical damage before use, and never attempt to disassemble or modify the pack. If you notice any swelling, unusual odour, or damage to the case, discontinue use immediately and dispose of the battery responsibly at your local electronics recycling facility.
