Panasonic Ncr21700t Datasheet 〈2026 Update〉

The voltage is held at 4.2V while the current naturally tapers down. Charging terminates once the current drops below a designated threshold (usually around 50mA to 100mA). Discharge Performance Curves

The lithium-ion battery market has been dominated by the shift from the standard 18650 form factor to the larger, more energy-dense 21700 format. Leading this charge is Panasonic, a Tier-1 supplier whose cells power everything from electric vehicles (EVs) like Tesla to high-end consumer electronics. panasonic ncr21700t datasheet

Data parsed from official testing documentation yields a distinct profile for the bare cell: NCR21700 data sheet The voltage is held at 4

When building battery packs, a Battery Management System (BMS) must be wired to monitor over-charge, over-discharge, and over-current conditions. Leading this charge is Panasonic, a Tier-1 supplier

Providing maximum range for city commuting. Portable Power Stations & Energy Storage Systems (ESS). High-End Flashlights: Requiring long runtime.

The Panasonic NCR21700T requires a CC‑CV (Constant Current / Constant Voltage) charging algorithm, which is standard for lithium‑ion cells:
