What Makes the Tenergy 18650 11.1V 4400mAh Battery Stand Out?

The Tenergy 18650 11.1V 4400mAh Li-Ion Rechargeable Battery stands out for its high energy density, long cycle life, and reliable performance. Designed for devices requiring sustained power, it features a 3-cell configuration, overcharge/discharge protection, and a lightweight build. Ideal for drones, power tools, and medical equipment, it balances capacity and voltage for efficiency and safety.

How to Prevent Lithium-Ion Battery Fires and Explosions

What Are the Technical Specifications of the Tenergy 18650 Battery?

The Tenergy 18650 offers 11.1V nominal voltage, 4400mAh capacity, and a 3S1P configuration. Its lithium-ion chemistry ensures up to 500 charge cycles with minimal capacity loss. Operating temperatures range from -20°C to 60°C. Built-in safety mechanisms include overcurrent, short-circuit, and thermal protection, ensuring stable performance in high-drain applications like RC vehicles and portable electronics.

Specification	Value
Voltage	11.1V
Capacity	4400mAh
Cycle Life	500 cycles
Weight	210g

For users requiring precise power management, the 3S1P configuration allows balanced energy distribution across cells. This setup is particularly beneficial for industrial applications where voltage consistency is critical. The battery’s ability to maintain stable output even in subzero temperatures makes it suitable for outdoor equipment used in harsh environments.

How Does the Tenergy 18650 Ensure Safety During Use?

Safety is prioritized through a multi-layered protection PCB, which prevents overcharging (above 12.6V), over-discharging (below 8.4V), and short circuits. The battery’s flame-retardant casing and thermal fuses mitigate fire risks. Users should store it in non-conductive cases and avoid puncturing or exposing it to moisture for optimal safety.

The protection PCB continuously monitors cell voltage and temperature, automatically disconnecting the circuit during anomalies. This feature is crucial for high-risk applications like medical devices, where failure could have severe consequences. Additionally, the battery’s robust casing resists impact damage, reducing the likelihood of internal short circuits caused by physical stress.

How Does It Compare to Brands like Panasonic or Samsung?

Unlike Panasonic’s NCR18650B (3400mAh) or Samsung’s 30Q (3000mAh), Tenergy’s 4400mAh offers higher capacity but slightly lower energy density. It excels in cost-effectiveness and bundled safety features, whereas competitors focus on raw performance. Best for budget-conscious users needing balanced specs.

Brand	Capacity	Cycle Life	Price Range
Tenergy	4400mAh	500 cycles	$25-$35
Panasonic	3400mAh	600 cycles	$40-$50
Samsung	3000mAh	400 cycles	$30-$40

While Panasonic cells offer marginally better longevity, Tenergy provides a 15% higher capacity at a 30% lower price point. This makes it ideal for applications where runtime outweighs the need for ultra-compact sizing. However, Samsung’s 30Q remains popular for high-drain devices due to its lower internal resistance.

“The Tenergy 18650 strikes a rare balance between affordability and reliability. Its multi-protection system is a standout for DIY enthusiasts and professionals who prioritize safety without sacrificing runtime.” — Industry Expert, Power Solutions Sector.

FAQs

Can I Use This Battery for My Vape Mod?

Yes, if the mod supports 11.1V input. Check compatibility with your device’s specifications to avoid damage.

How Long Does a Full Charge Last?

Depending on usage, 4-6 hours in drones or 2-3 days in medium-drain devices. High-drain applications reduce runtime.

Is It Safe to Carry on Airplanes?

Per FAA rules, batteries ≤100Wh (like this 48.8Wh unit) are allowed in carry-ons. Declare them and cap terminals.
