Liitokala Lii-500 4-Slot Lithium Battery Charger

The Liitokala Lii-500 is a four-slot smart charger designed for cylindrical lithium-ion and Ni-MH batteries including 18650, 26650, AA, and AAA sizes. It supports independent charging, capacity measurement, internal resistance detection, and USB 5V power output. Built-in safety features include overcharge, short-circuit, temperature, and reverse-polarity protection, plus zero-voltage battery activation. The device uses a single LCD screen to show real-time voltage, current, time, capacity, and internal resistance.
Key Features:
- Four independent charging slots with selectable currents (300mA / 500mA / 700mA / 1000mA)
- Supports simultaneous charging and testing of mixed battery types (Li-ion and Ni-MH)
- LCD display shows voltage (V), current (mA), time (h), capacity (mAh), and internal resistance (m)
- Three operating modes: CHARGE, FAST TEST (2-step), and NOR TEST (3-step) for accurate capacity measurement
- Built-in 5V/1000mA USB output powered by 1-4 Li-ion cells (not compatible with Ni-MH for USB output)
Ideal For:
- Recharging batteries used in flashlights, power tools, digital cameras, and instrumentation
- Testing battery health and remaining capacity before reuse or replacement
- Users needing portable, multi-battery charging with real-time diagnostics
Specifications:
- Input: DC 12V/2A (adapter included)
- Compatible battery types: 18650, 26650, AA, AAA (Li-ion and Ni-MH only)
- Not compatible with LiFePO4 batteries
- Operating environment: indoor use only
- Safety protections: overcharge, over-discharge, short-circuit, thermal, reverse-polarity, and low-voltage lockout (1.65V-2.2V range disabled)
