Datasheet 2021 - Panasonic Ncr21700t
For context, a standard high-quality 18650 cell typically offers between 3000 mAh and 3500 mAh. By switching to the 21700 format and the NCR21700T chemistry, designers gain nearly 50% more capacity per cell. This reduction in cell count (fewer cells needed to achieve a target Watt-hour rating) simplifies Battery Management Systems (BMS) and reduces welding points, increasing overall pack reliability.
Stage 1: Constant Current (CC) | Stage 2: Constant Voltage (CV) (Current is capped; Voltage rises) | (Voltage is locked; Current drops) --------------------------------------|------------------------------------ Current (A) : [====== Capped ======] | Current (A) : [== Tapering Down =>] Voltage (V) : [== Rising to 4.2V ==] | Voltage (V) : [==== Locked 4.2V ===]
The Panasonic NCR21700T is a premier choice for designers looking to maximize runtime and energy density in their products. As seen in the detailed specification overview, its 4800-5000mAh capacity makes it an industry leader for high-capacity 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
The NCR21700T (and the 21700 format in general) was the catalyst for moving away from the classic 18650 standard. Energy Density:
Regularly inspect the outer PVC shrink wrap for tears to prevent accidental shorts.
This comprehensive guide breaks down the Panasonic NCR21700T datasheet, exploring its core specifications, performance curves, safety features, and ideal use cases. 1. Overview and Key Features For context, a standard high-quality 18650 cell typically

Datasheet Analysis and Performance Evaluation Cell Model: NCR21700T Manufacturer: Panasonic Corporation
At ~5000mAh, these are among the highest capacity 21700s you can get. Moderate Power: Stage 1: Constant Current (CC) | Stage 2:
The BMS or mechanical fuses must interrupt circuit flow if the current exceeds the continuous rated limits.
The Panasonic NCR21700T is specifically known for its superior energy density, making it a "long-range" cell rather than a pure high-power cell. A. Exceptional Energy Density
