The Tenergy PCB 11.1V Li-Ion Battery Pack 3A 11A is a high-performance power solution designed for devices requiring stable voltage and extended runtime. With a 3A continuous discharge rate and 11A peak capability, it balances energy density and safety. Its built-in protection circuit prevents overcharging, overheating, and short circuits, making it ideal for drones, RC vehicles, and portable electronics.
How to Prevent Lithium-Ion Battery Fires and Explosions
What Are the Key Specifications of the Tenergy PCB 11.1V Battery?
The Tenergy PCB 11.1V battery operates at 11.1 volts with a nominal capacity of 3300mAh. It supports continuous discharge rates of 3A and peaks at 11A for short bursts. The lithium-ion cells are arranged in a 3S configuration (3 cells in series), and the integrated PCB ensures voltage stability. Its compact design weighs 220g, making it portable for on-the-go applications.
| Parameter | Specification |

| Cell Configuration | 3S1P (3 cells in series) |
| Energy Density | 122Wh/kg |
| Operating Temp | -20°C to 60°C |
How Does the Protection Circuit Enhance Battery Safety?
The built-in PCB monitors voltage, current, and temperature in real time. It automatically cuts off power during overcharge (above 12.6V), over-discharge (below 9V), or short-circuit scenarios. Thermal protection activates at 70°C (158°F), preventing catastrophic failures. This multi-layered safety system extends battery lifespan by 20-30% compared to unprotected alternatives.
The protection circuit employs three redundant voltage sensors that cross-verify readings every 50 milliseconds. This failsafe mechanism prevents false triggers while maintaining rapid response times – critical for high-speed drones where sudden power cuts could cause crashes. The system also features a self-recovery function: after resolving an overcurrent event, it automatically restores power when stable conditions persist for 15 seconds.
Which Devices Are Compatible with This Battery Pack?
This battery powers drones (DJI Phantom series), RC cars (Traxxas models), LED lighting systems, and medical devices like portable oxygen concentrators. Its XT60 connector ensures compatibility with most hobbyist electronics. Always verify voltage requirements—devices designed for 3S LiPo/Li-ion setups (9.9V–12.6V) work seamlessly with this pack.
For industrial applications, the battery reliably operates security cameras for 18-22 hours per charge and powers robotic vacuum cleaners through 3-4 cleaning cycles. Compatibility extends to photography equipment like DSLR camera gimbals, where its low electromagnetic interference prevents signal disruption. Users should confirm polarity matches their device – reverse polarity could activate the PCB’s protection mode despite the physical connector fit.
“The Tenergy PCB 11.1V represents a leap in hobbyist-grade battery tech,” says Dr. Elena Marquez, a battery systems engineer. “Its hybrid NMC chemistry and adaptive PCB algorithms address the voltage sag that plagues RC applications.”
FAQ
- How Long Does a Full Charge Take?
- Using a 2A charger, full recharge takes 2.5 hours. A 1A charger extends this to 4 hours.
- Is This Battery Airline-Approved?
- Yes, it complies with IATA’s 100Wh limit (11.1V × 3.3Ah = 36.6Wh). Carry it in cabin baggage.
- Can It Power Solar Storage Systems?
- No—Li-ion chemistry isn’t optimal for deep-cycle solar applications. Use LiFePO4 batteries instead.
