Universal LiitoKala Lii-CH4 5V 2A 4-Channel Charger

The LiitoKala Lii-CH4 is a compact and reliable solution for charging various batteries. Manufactured by Liitokala, this device features four independent channels, allowing simultaneous charging of up to four cells of different types and states. It is a universal charger for users working with Li-ion, IMR, LiFePO4, as well as NiMH and NiCd batteries.

Key Features

• Support for Various Battery Types. The device is compatible with Li-ion (3.7V/3.8V), IMR, LiFePO4 (3.2V), and NiMH/NiCd (1.2V). Supported sizes include 26650, 21700, 20700, 18650, 18490, 18350, 17670, 17500, 16340 (RCR123), 14500, 10440, as well as AA, AAA, SC, and C type cells.
• Four Independent Channels with Individual Control. Each channel has its own button for selecting the charging mode and current. This allows simultaneous charging of different battery types without waiting for one cycle to complete.
• Voltage Selection and Automatic Type Detection. The output voltage is selected based on the battery type: 4.35V, 4.2V, 3.65V, or 1.48V. Many cell types are automatically detected within approximately 9 seconds; for LiFePO4 and IMR, the charge type must be selected manually.
• Adjustable Charging Current. For each channel, 500mA or 1000mA modes are available. When charging 1.5V lithium cells, the current is fixed at 500mA.
• LCD Display for Parameter Monitoring. The screen displays the current channel, voltage, battery type, set charging current, charging time, and accumulated capacity.
• Safety and Recovery. The device supports low-voltage activation for recovering deeply discharged cells, automatically detects faulty batteries, and protects against overcharge, overdischarge, short circuit, and incorrect polarity connection.
• Durable Casing and Cooling. The casing is made of ABS plastic and PC, resistant to mechanical damage. Ventilation holes on the back panel dissipate heat, reducing the risk of overheating during prolonged use.
