Panasonic Ncr21700t Datasheet [work] Jun 2026

The Panasonic NCR21700T is a high-capacity 21700-format lithium-ion cell commonly used in energy storage, e-bikes, power tools, and high-capacity battery packs. Below is a concise, shareable post summarizing its datasheet specifications, performance characteristics, and usage considerations.

-20°C to 60°C (Low-temperature discharge reduces effective capacity due to increased internal resistance; high-temperature discharge accelerates chemical aging).

The Ultimate Guide to the Panasonic NCR21700T Li-ion Battery: Datasheet Analysis, Specs, and Applications

. This cell isn't just a battery; it’s a solution to the "range anxiety" that haunted the early 2010s. Products for Business - Panasonic Energy Co., Ltd. panasonic ncr21700t datasheet

Offers better thermal stability and capacity retention than standard cobalt-only cells.

While the cell boasts a high nominal capacity of 4800mAh, its internal resistance is optimized to support high-drain applications. It can comfortably sustain continuous discharge currents up to 15A without significant voltage sag. Under controlled thermal conditions (where cell temperature does not exceed 60°C), peak bursts or elevated continuous discharge up to 20A can be achieved, though this may accelerate cycle degradation. Environmental and Temperature Limits

Avoid charging to 4.2V and discharging to 2.5V. Restricting cycles between 4.1V and 3.0V can easily double or triple the cell's lifespan. The Ultimate Guide to the Panasonic NCR21700T Li-ion

The NCR21700T utilizes a standard Constant Current / Constant Voltage (CC/CV) charging profile. Charging Behavior

Reaches ~775 Wh/l, making it ideal for compact battery packs.

The cell can sustain high-drain pulses provided the internal cell temperature does not exceed 60°C (140°F) . Offers better thermal stability and capacity retention than

Avoid storing or discharging the cell in environments exceeding 45°C.

Engineered to strict manufacturing tolerances for predictable performance in multi-cell packs. 2. Technical Specifications Matrix
