The All-in-One Solution for Battery Management
At Sun Cheong Computer, we understand that reliable power is crucial for everything from gaming mice to high-end flashlights. The LiitoKala Lii-M4S isn't just a charger; it is a complete battery management system designed to extend the life of your rechargeable cells.
Smart Touch Control & Real-Time Monitoring
Gone are the clunky buttons of the past. The Lii-M4S features a sleek, responsive touch control panel. The high-contrast LCD screen provides real-time data for each slot independently, displaying Voltage (V), Current (mA), Time (h), and Capacity (mAh). You will know exactly how much power your battery holds.
"Storage Mode": The Battery Saver
Most batteries degrade because they are stored fully charged or completely empty. The Lii-M4S features a professional Storage Mode.
- How it works: It automatically charges or discharges your Li-ion battery to the optimal 3.7V voltage.
- The Benefit: This prevents battery swelling and capacity loss during long periods of non-use—perfect for seasonal gear like drones or backup flashlights.
Professional Capacity Testing (Test Mode)
Do you suspect your old batteries are losing their edge? The Test Mode runs a full "Charge-Discharge-Charge" cycle to measure the actual discharge capacity of the battery. This allows you to identify weak cells and match healthy ones for balanced performance in multi-battery devices.
Universal Compatibility & Power Bank Feature
Whether you use 18650, 21700, 26650 Li-ions, or standard AA/AAA NiMH batteries, the independent 4-channel system handles them all simultaneously. Plus, by inserting a charged Li-ion battery into Slot 4, the unit converts into a 5V USB Power Bank to charge your phone in an emergency.

FAQ Section
FAQ Section
Q: Can this charger charge 1.5V AA Lithium batteries?
A: No, this model supports 3.7V Li-ion and 1.2V NiMH/NiCd batteries. It does not support 1.5V constant voltage Lithium or 3.2V LiFePO4 batteries.
Q: What is the difference between "Test" and "Storage" modes?
A: "Test" mode fully charges and discharges the battery to measure its total capacity (mAh). "Storage" mode adjusts the battery to 3.7V (approx. 50-60% charge), which is the safest voltage for long-term storage to prevent degradation.
Q: Does the package come with a wall adapter?
A: The package includes the Lii-M4S charger and a high-quality USB-C cable. You can use any standard 5V/2A USB phone adapter (Samsung, Apple, etc.) to power it.
