What Are the Key Technical Specifications of the Tenergy 9.6V Battery Pack?
The Tenergy 9.6V NiMH Battery Pack delivers 2000mAh capacity with a nominal voltage of 9.6V, structured as an 8-cell configuration. It supports up to 1,000 charge cycles, operates between -20°C to 60°C, and features low self-discharge (15% monthly). The pack includes a standard Tamiya connector and is UL/CE/RoHS certified for safety and environmental compliance.
The 8-cell design uses sub-C sized NiMH cells arranged in series to achieve the 9.6V output. Each cell contributes 1.2V, with a robust nickel strip welding process ensuring minimal internal resistance. This configuration allows sustained current delivery up to 15A, making it suitable for RC vehicles with high-torque motors. The pack’s energy density of 60Wh/kg outperforms older NiCd models while maintaining safer chemistry.
| Parameter | Specification |
|---|---|
| Charge Time | 2-3 hours (1A charger) |
| Peak Current | 15A (pulse discharge) |
| Cell Type | Sub-C NiMH |
How Does the Tenergy Battery Pack Compare to Lithium-Ion Alternatives?
While lithium-ion batteries offer higher energy density, the Tenergy NiMH pack excels in safety (no thermal runaway risk), wider temperature tolerance, and lower cost. It’s preferable for applications where frequent partial charging occurs, as Li-ion batteries degrade faster under similar conditions.
In cold environments (-10°C), the Tenergy NiMH retains 85% of its capacity compared to lithium-ion’s 50-60% performance drop. For hobbyists using RC vehicles in winter, this translates to more consistent runtimes. The pack’s inherent stability also eliminates the need for complex battery management systems (BMS), reducing overall system weight by 18-22% in comparable setups.
| Feature | NiMH | Li-ion |
|---|---|---|
| Thermal Runaway Risk | None | Moderate |
| Partial Charge Cycles | Unlimited | 500 max |
FAQs
- How Long Does the Tenergy 9.6V Battery Last Per Charge?
- Runtime depends on device power draw: RC cars typically get 25–35 minutes, while low-drain devices like LED lights can run 8–12 hours.
- Can I Use a Standard AA Charger for This Battery Pack?
- No. The pack requires a 9.6V NiMH charger with Tamiya connector compatibility. Using AA chargers may cause improper charging and damage.
- Is It Safe to Leave the Battery Charging Overnight?
- While the pack has overcharge protection, prolonged charging accelerates wear. Use a charger with auto-shofft and avoid unattended charging beyond 2–3 hours.
