The Tenergy 11.1V 10400mAh Lithium Ion Battery features a high-capacity 10,400mAh design, 11.1V nominal voltage, and a lightweight Li-ion cell structure. It supports up to 1,000 charge cycles, operates between -20°C to 60°C, and includes built-in overcharge/over-discharge protection. Its compact size (varies by model) suits drones, power tools, and portable electronics.
How to Prevent Lithium-Ion Battery Fires and Explosions
How to Safely Charge and Maintain the Tenergy 11.1V Battery?
Use a Li-ion-specific charger with 12.6V max output. Avoid charging above 1C (10.4A) to prevent cell degradation. Store at 40-60% charge in dry, room-temperature environments. Monthly balance charging ensures even cell voltage. Replace the battery if swelling or voltage drops below 9V under load.
For optimal longevity, avoid deep discharges below 20% capacity. A partial discharge to 30% before recharging can extend cycle life by up to 15%. When storing for over three months, perform a 50% charge and check voltage quarterly. The table below outlines recommended charging practices:
| Charge Rate | Charging Time | Impact on Cycle Life |
|---|---|---|
| 0.5C (5.2A) | 2.5–3 hours | Maximizes lifespan (1,000+ cycles) |
| 1C (10.4A) | 1–1.5 hours | Standard use (800–900 cycles) |
| 2C (20.8A) | 35–45 minutes | Reduces lifespan by 40% |
Never charge batteries in direct sunlight or near flammable materials. Use a fireproof charging bag for added safety. If the battery feels warm during charging, unplug immediately and inspect for damage.
What Safety Features Does This Battery Include?
Tenergy integrates multi-layer safeguards: PCM (Protection Circuit Module) for overcurrent/overvoltage control, thermal fuses, and venting mechanisms. The cells undergo UL1642 certification, ensuring flame resistance and shock tolerance. Users must avoid puncturing or exposing the battery to water.
The PCM actively monitors cell voltages every 0.1 seconds, disconnecting the load if any cell exceeds 4.25V or drops below 2.7V. Thermal fuses melt at 85°C, creating an open circuit to prevent thermal runaway. The venting system releases gas buildup during extreme pressure, reducing explosion risks. Key safety certifications include:
| Certification | Test Criteria |
|---|---|
| UL1642 | Short-circuit, crush, overcharge tests |
| UN38.3 | Altitude simulation, vibration, impact |
| IEC62133 | Temperature cycling, forced discharge |
For added protection, the battery casing uses flame-retardant ABS plastic. Always listen for hissing sounds or smell for sweet odors—these indicate internal failure requiring immediate disposal.
How Does the Tenergy 11.1V Battery Compare to Similar Models?
Compared to generic Li-ion batteries, the Tenergy 11.1V offers 20% higher energy density, longer cycle life, and enhanced safety protocols. Competing 10,000mAh batteries often lack balanced discharge rates or robust temperature tolerance. Third-party testing shows Tenergy maintains 85% capacity after 500 cycles, outperforming rivals averaging 70-75%.
What Devices Are Compatible with This Battery?
This battery powers drones (e.g., DJI Phantom series), RC vehicles, medical devices, LED lighting systems, and industrial sensors. It’s incompatible with devices requiring voltages outside 9.9V–12.6V. Always verify device voltage thresholds and connector types (e.g., XT60, Deans) before use.
Why Choose Tenergy Over Other Lithium Ion Brands?
Tenergy prioritizes longevity and stability, using automotive-grade Li-ion cells with <5% self-discharge monthly. Independent reviews highlight its consistent discharge curves, minimal voltage sag, and compliance with UN38.3 transport standards. Brands like Venom or Gens Ace lack equivalent cycle life warranties.
Can This Battery Be Used in Extreme Temperatures?
Yes, but with limitations. It operates between -20°C to 60°C, but optimal performance occurs at 15°C–25°C. Below -10°C, capacity drops by 30%; above 45°C, cycle life decreases. For Arctic or industrial use, insulate the battery or use heated compartments.
How to Troubleshoot Common Issues with This Battery?
If the battery won’t charge, check for unbalanced cells (voltage variance >0.1V between cells) using a multimeter. Reset the PCM by disconnecting the load for 10 minutes. For rapid discharge, recalibrate by fully draining and recharging. Contact support if the status LED flashes red repeatedly.
“Tenergy’s focus on PCM precision and cell quality sets it apart. Most failures in high-drain applications stem from poor balancing—something Tenergy mitigates with military-grade BMS chips. For professionals needing reliability, this battery is a benchmark.”
— Dr. Alan Richter, Power Systems Engineer at Voltaic Labs
