Panasonic Ncr21700t Datasheet - !!better!!

Q: What is the difference between the NCR21700T and other Panasonic battery cells? A: The NCR21700T is a specific lithium-ion battery cell model from Panasonic, offering a unique combination of energy density, cycle life, and discharge rate.

Understanding the core parameters is essential for safe battery integration. Below are the key nominal specifications derived from the manufacturer's technical documentation. General Cell Architecture

Properly managing charge and discharge cycles ensures optimal cell longevity and prevents thermal runaway.

When pushed to its maximum continuous discharge limits (15A–30A), "voltage sag" occurs. This temporary drop in operating voltage is caused by internal resistance. Proper thermal management is mandatory at high discharge currents to prevent the cell from exceeding its maximum thermal threshold. 3. Thermal Limits and Environmental Operating Ranges

, 3.7V , or 4.2V devices, but must be used with a proper BMS for safety. The cell has no built-in protection circuit (PCM).

15A (with temperature monitoring) Operating Temperature (Charge): 0°C to 45°C Operating Temperature (Discharge): -20°C to 60°C Charge and Discharge Profiles

Lithium-ion cells store immense energy and require strict handling protocols.

When evaluating the Panasonic NCR21700T against other popular 21700 cells, it is important to focus on its energy‑oriented design: Q: What is the difference between the NCR21700T

Typical retail pricing varies by quantity and region:

Cycle life is highly dependent on Depth of Discharge (DoD) and ambient temperature.

Here are the key specifications of the Panasonic NCR21700T:

The voltage is held at 4.2V while the current naturally tapers down. Charging terminates once the current drops below a designated threshold (usually around 50mA to 100mA). Discharge Performance Curves Below are the key nominal specifications derived from

Safety and longevity depend heavily on staying within these thermal windows. 10°C to 45°C Discharging: -20°C to 60°C Storage (1 year): -20°C to 20°C Energy Density: ~263 Wh/kg (Gravimetric) 🛠️ Key Performance Features

To maximize the cycle life and safety of the NCR21700T, strict adherence to the datasheet's electrical curves is required. Charging Profile

When assembling multiple NCR21700T cells into a custom battery pack, a dedicated Battery Management System is mandatory. The BMS must offer the following hardware protections:

Charging below 0°C causes lithium plating and short circuits. -20°C to 60°C Exceeding 60°C triggers accelerated chemical aging. Thermal Runaway Point Exceeding 130°C causes catastrophic cell failure and fire. Storage Temperature -20°C to 20°C (Long-term) Keep at 30% to 50% State of Charge (SoC) for storage. Primary Industrial and Commercial Applications

Optimal charging occurs between 10°C and 45°C , while discharge is safe from -20°C up to 60°C . NCR21700T vs. NCR21700A NCR21700 data sheet
