Short Answer: The Tenergy 11.1V 2600mAh Li-Ion Battery 31013 is a high-performance rechargeable battery pack optimized for devices requiring stable voltage and portability. Its lithium-ion chemistry ensures lightweight design, low self-discharge, and compatibility with drones, RC vehicles, and medical equipment. Safety features like overcharge protection and a 1,000-cycle lifespan make it ideal for industrial and hobbyist applications.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does the Tenergy 31013 Battery Compare to Other Li-Ion Packs?
The Tenergy 31013 outperforms standard Li-ion batteries with its 11.1V output (3-cell configuration) and 2600mAh capacity, balancing energy density and size. Unlike generic packs, it includes a built-in PCM for overcurrent/overdischarge protection and supports 2C fast charging. Competitors like Venom or Zeee lack its military-grade casing and -20°C to 60°C operational range.
What Devices Are Compatible With This Battery?
Compatible devices include DJI Phantom drones, Traxxas RC cars, CCTV cameras, portable projectors, and cordless medical tools. Its XT60 connector works with most hobbyist systems, while the 31x51x21mm dimensions fit standardized compartments. Always verify voltage requirements—11.1V suits 3S LiPo configurations but may damage 7.4V devices without voltage regulators.

Why Choose Lithium-Ion Over Other Battery Chemistries?
Li-ion offers 150Wh/kg energy density vs NiMH’s 100Wh/kg, enabling lighter builds. It maintains 80% capacity after 500 cycles compared to LiPo’s 300-cycle average. Unlike lead-acid, it doesn’t require maintenance charging and operates efficiently in sub-zero temperatures. The Tenergy 31013’s 1% monthly self-discharge rate beats NiCd’s 20%, making it superior for intermittent-use devices.
Advanced lithium cobalt oxide (LCO) cathodes in the 31013 provide 3.7V nominal voltage per cell, outperforming lithium iron phosphate (LFP) cells used in solar storage. While LFP offers longer cycle life (2000+ cycles), the 31013’s chemistry delivers 40% higher peak currents crucial for drone ascents. Its operating altitude range (-500m to +9000m) surpasses NiMH batteries that fail above 5000m due to pressure changes.
| Chemistry | Energy Density | Cycle Life | Weight (per kWh) |
|---|---|---|---|
| Li-Ion (31013) | 150Wh/kg | 1000 | 6.7kg |
| LiPo | 130Wh/kg | 300 | 7.7kg |
How to Safely Charge and Maintain the Tenergy 31013?
Use a balanced Li-ion charger at 2.6A max (1C rate). Storage voltage should be 11.4V (3.8V/cell). Avoid depleting below 9V—the PCM disconnects at 8.7V to prevent damage. For longevity, charge at 0.5C in temperatures between 10°C-45°C. Monthly full discharge/recharge cycles help calibrate capacity readings.
What Safety Certifications Does This Battery Hold?
The 31013 meets UN38.3 (air transport), UL2054 (cell level), and IEC62133 standards. Its flame-retardant ABS casing (94V-0 rating) withstands nail penetration tests. Each batch undergoes internal resistance checks (±25mΩ tolerance) and thermal shock testing (-40°C to +85°C cycling).
Can You Rebuild a Tenergy 31013 Battery Pack?
Yes, using 3x 18650 cells (e.g., Samsung INR18650-25R) with spot-welded nickel strips. However, disassembling voids the 18-month warranty. DIY packs often lack factory-grade cell matching—Tenergy tests for ±0.05V voltage deviation across cells, which homemade packs rarely achieve.
Expert Views
“The Tenergy 31013’s true innovation is its hybrid PCB design. Most packs use separate protection and balancing circuits, but their integrated board minimizes voltage drops during high-current bursts. For FPV drone racers pulling 30C+ amps, this translates to 12% fewer voltage sag incidents compared to similarly priced batteries.” — Dr. Elena Marquez, Power Systems Engineer
Conclusion
Balancing industrial-grade safety with hobbyist-friendly features, the Tenergy 31013 redefines mid-tier Li-ion performance. Its niche lies in supporting high-drain devices where weight matters—delivering 23% more runtime per gram than competitors. While not the highest-capacity option, its durability under extreme conditions makes it a workhorse for professionals needing reliable power.
FAQs
- How Many Amps Can the Tenergy 31013 Sustain?
- Rated for 26A continuous (10C), with 52A pulse (20C) for 10-second bursts. Exceeding this trips the PCM, requiring a charger reset.
- Does It Work With Solar Chargers?
- Only with MPPT controllers regulating input to 12.6V ±1%. Direct solar charging risks overvoltage—the PCM lacks reverse current protection.
- Is Airport Transportation Allowed?
- Yes, under IATA PI 965 Section II. The 96Wh rating (11.1V x 8.6Ah) falls below the 100Wh limit for passenger aircraft. Carry-on only—no checked baggage.
