For anyone delving into the world of high-performance battery applications, understanding the technical specifications is paramount. The Samsung 30t 21700 Datasheet serves as the definitive guide to one of the most sought-after 21700 lithium-ion cells. This document is not just a collection of numbers; it's a blueprint for unlocking the true potential of these powerhouses, ensuring optimal performance, safety, and longevity in a wide array of devices.
What is the Samsung 30t 21700 Datasheet and How is it Used?
The Samsung 30t 21700 Datasheet is an official document released by Samsung SDI, detailing all the critical electrical, mechanical, and safety characteristics of their 30T model 21700 lithium-ion battery cell. It's the go-to resource for engineers, designers, and hobbyists who need precise information to integrate these cells into their projects. This datasheet outlines key figures such as:
- Nominal Capacity (mAh)
- Nominal Voltage (V)
- Maximum Continuous Discharge Current (A)
- Internal Resistance (mΩ)
- Operating Temperature Range (°C)
- Dimensions and Weight (mm, g)
Understanding these specifications is crucial for several reasons. For instance, knowing the maximum continuous discharge current prevents overheating and potential damage to the cell and the device it powers. Similarly, the operating temperature range ensures the battery functions reliably in various environments. This information is essential for designing safe and efficient battery packs that can meet the demands of applications like electric vehicles, power tools, high-end flashlights, and advanced vaping devices. Without this datasheet, users would be making educated guesses, which can lead to underperformance or dangerous situations.
The datasheet typically presents data in a clear and organized format, often including graphs and tables to illustrate performance curves under different conditions. For example, a discharge curve might show how the voltage drops over time as the battery is used, and a temperature graph might illustrate how the cell's performance is affected by external heat. Here's a glimpse of what you might find:
| Parameter | Typical Value |
|---|---|
| Nominal Capacity | 3000 mAh |
| Nominal Voltage | 3.6V |
| Max. Continuous Discharge Current | 35A |
These are just a few examples, but the full datasheet provides a comprehensive overview. Designers use this data to calculate total energy capacity for a battery pack, determine the number of cells needed in parallel and series configurations, and select appropriate battery management systems (BMS) to protect the cells. For example, if a project requires a sustained output of 100A, knowing the 30T's 35A continuous discharge limit, a designer would need at least four cells in parallel to safely achieve that output (4 cells * 35A/cell = 140A capability, providing a buffer).
We strongly encourage you to consult the official Samsung 30t 21700 Datasheet for the most accurate and detailed information. This resource is invaluable for anyone aiming to harness the full capabilities of these exceptional batteries.
