New Functions & Upgrades
1. Touch Buttons
Physical buttons are canceled, and touch buttons are adopted for more convenient and responsive operation. A beep sound will be emitted when the button is touched, prompting successful operation. There are 4 touch points in total: mode selection (MODE), channel 1-2 query, channel 3-4 query, and current selection (CURRENT), which also have the function of turning on the LCD backlight.
2. HD LCD Screen
Equipped with an HD LCD screen, featuring high definition and 175-degree wide viewing angle. All key data (voltage, current, power percentage, time, capacity) is displayed on a single screen, making it clear and easy to monitor the working status of the charger and batteries at a glance.
3. Added Functional Modes (Discharge & Storage)
- Storage Mode: A functional mode designed for safer battery storage. When the battery is not used for a long time (e.g., more than 1 week), this mode can be used to adjust the battery voltage to 3.8V (either charge or discharge to 3.8V), returning the battery to the factory voltage range (3.65-3.8V). This effectively extends battery life and ensures safer storage.
- Discharge Mode: Simply discharges the battery until it is empty, then automatically stops. This mode helps detect the actual discharge capacity of the battery and can also be used to activate over-discharged batteries appropriately.
Key Advantages
- 4 independent charging channels, supporting mixed charging of different types and specifications of batteries without mutual interference.
- Multiple adjustable charging and discharging currents, adapting to different battery capacities and usage needs.
- USB power bank function, which can be used as an emergency power supply for small digital devices (subject to usage conditions).
- Multiple safety protection functions, including overcharge protection, over-discharge protection, short-circuit protection, 0V battery activation, reverse battery detection protection, and intelligent identification of defective batteries.
- Compact and lightweight design, easy to carry and store, suitable for home, travel, and outdoor scenarios.
Package Includes
- 1 × LiitoKala Lii-M4S Battery Charger
- 1 × USB Cable
- 1 × User Manual (Chinese, English, Russian)
Safety Notes
- This charger is only suitable for cylindrical Li-ion and Ni-MH/Cd batteries; do not charge LiFePO4 batteries or disposable batteries (e.g., alkaline batteries) to avoid damage or danger.
