The LiitoKala Lii-500 Smart Battery Charger is a professional-grade multi-functional charger and capacity tester designed for Li-ion, LiPo, Ni-MH, and NiCd rechargeable batteries. It supports multiple cell sizes such as 18650, 26650, 14500, 21700, AA, AAA, and more, making it ideal for everyday users, hobbyists, and professionals needing accurate charging and testing.

With four independent charging slots, each controlled separately, the Lii-500 allows you to charge, discharge, test, and analyze battery capacity simultaneously. It features adjustable charging current modes (500mA, 700mA, 1000mA, and 2000mA for 2 slots) and dual discharging modes (250mA and 500mA), providing flexibility for different battery types and capacities.

Its clear LCD screen displays real-time charging data including voltage (V), current (mA), time (h), and capacity (mAh), ensuring complete visibility and control over every charging cycle. The built-in intelligent protection system safeguards against overcharging, over-discharging, short circuits, and reverse polarity. It also includes a USB output function (5V/1000mA) that allows the charger to work as a power bank when connected to AC power, offering added convenience.

How to Use:

1. Connect the power adapter (12V/3A DC) to the charger.

2. Insert batteries into the slots, ensuring correct polarity.

3. Select the mode (CHARGE, DISCHARGE, or TEST) using the “MODE” button.

4. Adjust current settings using the “CURRENT” button (500mA, 700mA, 1000mA, or 2000mA).

5. The LCD will display voltage, charging time, and capacity for each slot.

6. For NOR TEST mode, the charger will charge, discharge, then recharge to measure real capacity.

7. For FAST TEST mode, it discharges first, then charges to calculate the quick test result.

8. When charging is complete, the screen shows “FULL.”

9. For USB output, connect a USB device to the output port (requires AC input).
