Before we talk about heat, let us look at the cold, hard numbers from the official Panasonic/Sanyo datasheet.
On the surface, the NCR21700T is a direct competitor to the Samsung 40T and the Molicel P42A. However, unlike its rivals, the Panasonic cell uses a modified NCA (Nickel-Cobalt-Aluminum) chemistry that trades ultra-low resistance for higher energy density. panasonic ncr21700t datasheet hot
The search query “Panasonic NCR21700T datasheet hot” usually comes from one of three user groups: Before we talk about heat, let us look
All three groups notice the same thing: When you push this cell past 25A continuous, the temperature skyrockets. Here is what the datasheet implies but rarely states explicitly: The 35A rating is a "cutoff" limit, not a "comfortable continuous" limit. On the surface, the NCR21700T is a direct
Heat is generated based on internal resistance and the speed of discharge. The NCR21700T is an Energy Cell, not a Power Cell. This means it has high capacity but does not like "hot" (high amp) loads.
