Panasonic Ncr21700t Datasheet Hot Jun 2026

If your application demands ultra‑long runtime with moderate power draw, the NCR21700T is hard to beat. For maximum discharge rates, consider the Molicel P45B or Samsung 50S.

This article explores the technical datasheet of the Panasonic NCR21700T, specifically analyzing its specifications, performance, and thermal characteristics (how it handles "hot" or high-discharge conditions). 1. Technical Specifications of the Panasonic NCR21700T

The search for a reliable high-capacity, high-drain cylindrical cell frequently leads engineers and battery enthusiasts straight to the Panasonic NCR21700T panasonic ncr21700t datasheet hot

The cell does not have built-in protection (unprotected), so a robust BMS is required to manage temperature cut-offs. Summary of Thermal Performance

The NCR21700T runs hotter than the Samsung 40T under identical loads. Why? Higher internal resistance. While the datasheet claims <18mΩ, real-world DC internal resistance (DCIR) often measures 20-24mΩ at room temperature. As the cell heats up, resistance climbs, creating a vicious heat loop. including electric vehicles

Master Guide to the Panasonic NCR21700T Datasheet: Specs, High-Drain Performance, and EV Origins

Standardly rated at 15A, but often used up to 30A with proper thermal monitoring; peak bursts up to 40A are possible. Dimensions: 21.1mm diameter by 70.4mm height. renewable energy systems

The Panasonic NCR21700T is a high-performance lithium-ion battery cell designed for various applications, including electric vehicles, renewable energy systems, and industrial power tools. In this guide, we will explore the key features, specifications, and characteristics of the NCR21700T battery cell based on its datasheet.

If your NCR21700T consistently runs hot, you are effectively killing the cell after three months of daily use.
