BAK COP 30A 18650 2500mAh Rechargeable Battery

Overview

The BAK COP 30A 18650 is a rechargeable lithium-ion cell designed for devices that accept standard 18650 batteries. Based on retailer listings, it offers a 2500mAh capacity, 3.6V nominal voltage, and 4.2V maximum charge voltage. The cell is also listed with a 20A maximum discharge rating on some product pages, while other retailers describe the same BAK COP series as a high-current 30A cell, so the exact discharge specification should be confirmed against the specific cell marking or datasheet before use. As a bare battery cell, it is intended for compatible equipment that requires an unprotected 18650 format cell. For dependable performance, it should be charged only with a suitable lithium-ion charger and used within the limits specified by the device manufacturer. This makes it a practical option for users needing a compact, high-capacity 18650 cell with a balance of runtime and current delivery.
