The is an excellent, high-capacity, 21700 lithium-ion cell capable of high-drain tasks up to 15A continuously. While it can handle higher momentary loads, keeping the cell below 60°C is crucial for preserving its longevity and safety, as highlighted by its datasheet specifications.
If you exceed 35A (say, a dead short or a mod malfunction pushing 50A), the internal separator melts. This causes an internal short circuit. That heat, combined with the NCA chemistry, leads to "venting with flame."
Because Panasonic primarily supplies these to OEMs like Tesla, official retail datasheets can be elusive. Many users rely on community-tested models and digital twins from providers like Batemo for precision engineering. panasonic ncr21700t datasheet hot
The cell accepts an optimal charge envelope between . Forcing energy into the cell below 10°C induces a high risk of lithium plating on the anode, creating dangerous internal dendrites. 2. Discharge Thermal Boundaries
Because the Panasonic NCR21700T operates in a unique and dangerous gray area. On paper, it looks like a monster. In reality, pushing this cell to its limits generates significant heat—and sometimes, a fiery disaster. The is an excellent, high-capacity, 21700 lithium-ion cell
for high-drain performance, though standard industry cut-off is often cited at : Maximum of Промелектроніка Performance & Thermal Limits Discharge Rate
Due to its 5000mAh capacity and moderate (15A) discharge rating, this cell is ideal for: This causes an internal short circuit
The is a high-performance lithium-ion battery cell originally popularized as a primary component in Tesla Model 3 battery packs. While often difficult to find through official retail channels as a standalone consumer product, it is highly sought after in the DIY EV and flashlight communities for its balance of high capacity and discharge capability.
