LiitoKala Lii-32A 18650 3200mAh Battery

A regular choice for those seeking a reliable power source — the rechargeable Li-ion battery Liitokala Lii-32A in the popular 18650 form factor. This cell combines high capacity, compact dimensions, and enhanced safety measures, making it optimal for flashlights, portable equipment, and other devices with high power consumption.

The battery casing measures 65.5 x 18.5 mm and weighs 46 g, ensuring convenient installation and replacement in devices designed for 18650-size batteries. The nominal capacity is 3200 mAh, guaranteeing long operation without frequent recharges. The nominal voltage is 3.7 V, rising to 4.2 V when fully charged, and the deep discharge threshold is set at 2.5 V — these parameters ensure stable and safe battery operation across a wide range of operating conditions.

One of the important technical advantages is its low internal resistance of less than 35 mOhm, which allows for high current delivery with minimal energy loss and reduces heating under intense load. The battery's lifespan is approximately 1000 charge-discharge cycles without significant capacity degradation, making the Lii-32A a cost-effective solution for frequent use.

To enhance safety, the casing is equipped with a safety (explosion-proof) valve, which reduces risks associated with excessive pressure buildup and provides an additional level of protection against ignition or rupture. This makes the battery suitable for applications where a high level of reliability is crucial.
