Liitokala 1x18650 3400 mAh Green with protection (LII-34B-PCB)

High-capacity lithium-ion battery in the 18650 format, offering an optimal combination of significant capacity and enhanced operational safety. Unlike standard models without protection, this power cell is equipped with an integrated protection circuit board that prevents critically dangerous operating modes—overcharging, deep discharge, and short circuit. The Liitokala 1x18650 3400 mAh Green with protection battery stands out with an impressive capacity of 3400 mAh, which is one of the best indicators for cells of this size and provides significantly longer autonomous operation for connected devices between charging cycles.

The standard operating voltage of 3.7 V ensures compatibility with a wide range of devices using 18650 format cells. This model is perfect for devices where long runtime and safety are priorities—portable LED flashlights, digital audio players, compact radios, measuring devices, as well as various household and professional battery-powered devices. Thanks to the built-in protective electronics, these batteries are an excellent choice for novice users who have not yet had experience working with lithium-ion cells, as they minimize the risk of damage from improper use or application in suboptimal conditions.
