Frequently Asked Questions

• Is the Voltz 7.4V 1500mAh Li-Ion battery suitable for beginners in the RC hobby? — Yes, absolutely. This battery is an excellent choice for newcomers to RC because it's ready to use straight out of the box with its pre-installed Deans T-Plug connector, requires no complex configuration, and the lightweight Li-Ion chemistry means beginners won't struggle with excessive battery weight affecting their vehicle's handling. The low self-discharge characteristics also mean the battery will be ready to use whenever a beginner wants to enjoy their RC vehicle, without requiring frequent charging preparation.
• What vehicles can I use this battery with? — The Voltz 7.4V 1500mAh battery is specifically recommended for FTX Vortex, FTX Havok, and FTX Glader RC models. These vehicles are engineered to operate optimally with this precise voltage and capacity combination. The battery features the industry-standard Deans T-Plug connector, so it may also be compatible with other RC vehicles that feature Deans connectors, though you should verify voltage compatibility before use to avoid damaging your model's electronics.
• How long will this battery last between charges? — Runtime depends on several factors including your driving style, the specific RC vehicle being powered, terrain type, and motor efficiency. Generally, a 1500mAh capacity battery will provide between 10-30 minutes of continuous use, though careful driving and lighter throttle usage can extend this duration significantly. The low self-discharge rate means if you're not using your RC vehicle for several weeks, the battery will retain its charge better than older battery chemistries.
• What is Li-Ion chemistry and why is it better than alternatives? — Lithium-Ion technology represents the pinnacle of modern battery chemistry for RC applications. Compared to older lithium polymer (LiPo) or lead-acid batteries, Li-Ion offers superior energy density (more power in less weight), exceptional low self-discharge rates (the battery maintains its charge for months when not in use), and better cycle life longevity (the battery will function reliably for more charge-discharge cycles). For RC enthusiasts who want dependable performance without the weight penalty of older battery technologies, Li-Ion is the intelligent choice.
• How should I charge this battery safely? — The Voltz 7.4V 1500mAh battery features an XH balance connector that should be connected to a charger specifically designed for Li-Ion batteries with balance charging capability. Never use chargers designed for other battery chemistries, as this can damage the battery or create safety hazards. Always charge in a safe location away from flammable materials, never leave the battery unattended during charging, and discontinue charging immediately if you notice any signs of swelling, unusual heat, or damage to the battery case.
• Can I use this battery with my other RC vehicles? — If your other RC vehicles feature Deans T-Plug connectors and are engineered to accept 7.4V power input, this battery may be compatible. However, you must verify that the voltage matches your vehicle's specifications before connecting. Using incorrect voltage can damage your RC vehicle's electronic speed controller (ESC), receiver, and servo systems. If you're unsure about compatibility, contact our knowledgeable team at RC Model Shop and we'll help you determine whether this battery is suitable for your specific model.
• What does the XH balance connector do? — The XH balance connector is a specialised charging port that allows compatible chargers to monitor and equalise the voltage across each cell in the battery pack during the charging process. This prevents one cell from overcharging whilst others remain undercharged, which extends the battery's lifespan significantly and maintains optimal performance throughout its operational life. Always use a charger with balance charging capability for this battery to maximise its longevity.
• How do I store this battery properly? — Store your Voltz battery in the included soft protective case in a cool, dry location away from direct sunlight and extreme temperatures. Ideally, if you plan to store the battery for more than a few weeks without use, charge it to approximately 50-60% capacity before storage, as this is the optimal charge state for long-term battery health. Never store a fully charged or fully discharged battery for extended periods, as this can reduce its overall lifespan and performance.
