The Tenergy 31061 is a lithium-ion rechargeable battery with an 11.1V voltage and 2200mAh capacity, designed for high-drain devices like drones, RC vehicles, and power tools. Its lightweight design, stable discharge rate, and built-in protection circuits against overcharge/over-discharge make it ideal for applications requiring reliable, long-lasting power.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does the Tenergy 31061 Compare to Other Li-Ion Batteries?
The Tenergy 31061 outperforms standard Li-ion batteries with its 11.1V output (equivalent to 3-cell LiPo) and balanced energy density. Unlike cheaper alternatives, it includes a PCB for safety, supports up to 500 charge cycles, and maintains stable performance under high current draws. Competing models often lack comparable voltage consistency or thermal stability.
When tested against similarly priced 11.1V batteries, the Tenergy 31061 demonstrated a 12% longer runtime at 15C discharge rates. Its layered cell design minimizes internal resistance, allowing sustained 25A pulses without overheating. For comparison, generic Li-ion packs of the same capacity typically show voltage drops exceeding 0.8V under similar loads, while the Tenergy stays within 0.3V deviation.
| Feature | Tenergy 31061 | Standard 11.1V Li-Ion |
|---|---|---|
| Cycle Life | 500+ | 300-400 |
| Peak Current | 55A | 35A |
| Weight | 168g | 185g |
| Thermal Cutoff | 75°C | None |
Why Choose a 2200mAh Capacity for High-Drain Applications?
A 2200mAh capacity balances runtime and weight, providing ~30 minutes of continuous use for mid-sized drones. Higher capacities add bulk, while lower ones reduce operational time. The Tenergy 31061’s 25C discharge rate delivers instant power bursts without voltage sag, critical for responsive throttle control in RC applications.
This capacity sweet spot becomes evident when analyzing power-to-weight ratios. A 2200mAh battery provides 48.4Wh of energy (11.1V x 2.2Ah), sufficient for most 250-400mm drone frames. Heavier 3000mAh packs increase flight time by 8-10 minutes but add 35% more mass, requiring stronger motors that drain power faster. For FPV racers prioritizing agility, the Tenergy 31061’s 168g weight enables sharper maneuvers without sacrificing essential runtime.
| Capacity | Weight | Flight Time |
|---|---|---|
| 1500mAh | 125g | 18min |
| 2200mAh | 168g | 28min |
| 3000mAh | 227g | 36min |
What Devices Are Compatible with the Tenergy 31061?
This battery is optimized for devices requiring 9V–12V input, such as FPV drones, RC cars, LED lighting systems, and medical equipment. Its XT-60 connector ensures compatibility with most hobbyist electronics. Always verify voltage requirements and physical dimensions before use to avoid damage.
How to Safely Charge the Tenergy 31061 Battery?
Use a Li-ion-specific charger with a 0.5C–1C rate (1.1A–2.2A). Full charge time is ~2.5 hours. Never exceed 12.6V total voltage. Terminate charging if the battery exceeds 40°C (104°F). Storage should be at 50% charge in fireproof containers, away from flammable materials.
What Are Common Signs of Battery Degradation?
Look for reduced runtime (below 70% of original capacity), swelling, or voltage drops below 9V under load. The Tenergy 31061 typically lasts 2–3 years with proper care. Avoid deep discharges below 9.9V to prolong lifespan.
Can the Tenergy 31061 Be Repaired if Damaged?
Lithium-ion cells cannot be safely repaired by end users. If physical damage, leaks, or PCB faults occur, recycle the battery immediately. Replacement costs ($25–$35) are lower than fire risks from DIY repairs.
Expert Views
“The Tenergy 31061 fills a critical niche in mid-power applications. Its nickel-plated steel casing resists corrosion better than aluminum counterparts, and the multi-layer separator prevents internal short circuits. For hobbyists, it’s the sweet spot between cost and performance.”
