For mechanical design, the datasheet provides exact dimensions:
Your load exceeds 5A continuous, or you need fast charging (<1 hour).
The Panasonic NCR21700T‘s combination of high capacity and moderate discharge capability makes it suitable for a wide range of applications, particularly those where runtime is more important than peak power. panasonic ncr21700t datasheet
The Panasonic NCR21700T is typically available in a flat-top configuration, making it suitable for assembly into battery packs. ≤ 21.35mm Height: ≤ 70.3mm
Stage 1: Constant Current (CC) | Stage 2: Constant Voltage (CV) (Current is capped; Voltage rises) | (Voltage is locked; Current drops) --------------------------------------|------------------------------------ Current (A) : [====== Capped ======] | Current (A) : [== Tapering Down =>] Voltage (V) : [== Rising to 4.2V ==] | Voltage (V) : [==== Locked 4.2V ===] ≤ 21
Due to its high energy density per unit volume, the Panasonic NCR21700T is a primary choice for several industries:
Lithium Nickel Cobalt Aluminium Oxide (NCA) Anode Chemistry: Carbon / Silicon-based Package Style: Flat top (Unprotected industrial cell) Electrical Performance Nominal Capacity: 4800mAh (Typical) / 4700mAh (Minimum) Nominal Voltage: 3.6V to 3.7V Standard Charging Voltage: 4.20V (±0.05V) Discharge Cut-off Voltage: 2.50V Voltage rises) | (Voltage is locked
A mandatory hardware or software BMS must monitor individual cell voltages to prevent overcharging (>4.25V) and over-discharging (
