But in the battery world, “hot” is a double-edged sword. It can mean desirable (high performance, sought after) or dangerous (thermal runaway, capacity loss).
: Approximately 21.1mm in diameter and 70.4mm in length (Flat top style). Thermal & Safety Characteristics
The "hot" performance or thermal features relevant to this cell include: : Discharge : Safe operation between -20°C to +60°C . Charge : Recommended between 10°C to +45°C .
Capable of sustained high-current delivery, typically rated up to 40A for "hot" high-drain needs. Charge Voltage: Standard 4.20V .
But "hot" is not a marketing term; it is a physical reality. If you build a pack with these, you must design for thermal management—nickel strips wide enough to handle current, temperature sensors, and physical spacing for airflow.
