The LiitoKala Lii-202 is a highly versatile, dual-slot smart charger capable of charging nearly all types of cylindrical Li-ion, NiMH, and LiFePO4 batteries. It features an intelligent microcomputer management system that automatically identifies battery types (Li-ion 3.7V and Ni-MH 1.2V) while allowing manual selection for LiFePO4 and 3.85V Li-ion batteries. The charger is powered via a standard 5V Micro USB input and can also function as a portable power bank using a charged lithium battery. With its clear LED indicators and multiple safety protections, it is an essential tool for maintaining high-performance battery cells.
